AbstractThe development of a nation is determined by the robustness of its economy and the relative strength of its national currency compared to key global economic powers. Currency serves as a means of conducting transactions for goods and services, as well as a medium of communication that represents a nation's wealth. The Reserve Bank of India (RBI) determines the quantity of legal tender currency notes and coins to be circulated. Additionally, there is a new kind of currency known as E-currency, which is in the form of debit or credit cards. Throughout the history of cash, from its first circulation to the most recent technological advancements, there has always been a persistent risk of counterfeiting and distributing counterfeit money. The advancement of currency printing technology also contributes to the emergence of technological disparities in counterfeit currency production. In order to examine or identify counterfeit cash, it is essential to have a comprehensive understanding of the currency's evolution, including the raw materials used, substrate composition, printing techniques and methods, specialty inks, their unique characteristics and parameters, as well as the post-production processes employed in currency manufacturing. This article examines the generation and evolution of currency, with a specific focus on enhancing security features, printing techniques, and ink-based security measures. The goal is to strengthen currency and improve methods for investigating and detecting counterfeits, ultimately leading to the creation of an ideal currency.

1. INTRODUCTION

   The Reserve Bank of India (RBI) oversees issuing money in India. The demand for currency from the public and the requirement to keep an acceptable quantity of currency in circulation all play a role in determining the amount of money that the RBI prints each year. The RBI uses a variety of instruments, including open market operations, bank rate policy, and cash reserve ratio, to control the amount of money in the economy. These instruments are employed to carry out the monetary policy goals of the RBI and to affect the amount of credit available in the economy. The RBI also has an inflation objective, which it utilizes to inform its choices about monetary policy. The reserves the RBI has with it determine how much currency is issued throughout the nation.

   Currently, reserves refer to the following:

   1. Reserves of currency

   2. Reserves of foreign currency

   3. Receivables for just the Balance of Payment (BOP).

   Now, only the value of the nation's reserves may be used to produce currency; moreover, this reserve is owned by the government and not by the general population. For this reason, the government only prints the amount of money that can be supported by substantial reserves rather than merely printed paper. Any currency note has the phrase "I guarantee to pay the bearer the sum of xxx rupees" printed on it. This claim has significance tied to it and is not merely a statement. It implies that you will receive xxx rupees' worth of products or services. There wouldn't be any unpaid debts that governments must make to other nations, sometimes known as the "Balance of Payment," if money were merely a piece of paper.

   This payment represents the amount that the government must give to other nations in exchange for the commodities and services that it has imported or utilized. For the same reason, hostile nations attempt to spread counterfeit money to ruin our economy.For a genuine hundred rupee note, they give you a thousand rupee note. They will do this to remove the original, we immediately lose Rs. 900 due to the false Rs. 1000 note that is being circulated in its stead, while the nation that stole the Rs. 100 note gains Rs. 100. They will accumulate INR reserves in their nation, which may then be used to either buy or pay for goods that India offers to that nation.The International Monetary Fund, or IMF, which keeps an eye on both our currency and the currencies of all other nations. This group monitors all nations' reserves, economies, GDPs, net worths, BOPs, growth rates, inflation rates, etc. All the above easily comprise is that currency plays an important role for development of nation at all grounds viz GDP, foreign exchange, agricultural growth, and economic interaction between other financial bodies. While talking about the currency it is expected to have the legal physical tender sustain different handling conditions at individual level as well as the machining part involved in banking sector and retail distribution of customer and buyer end. According to annual report published by reserve Bank of India for financial 2022- 23 it shows over aur 34000

   billion worth currency tenders are in Indian market and for production of one currency tender it cost about average 2.2 rupees edition to the value of currency tender. If considering the cost of production of legal tender material required, the manpower assigned for the production and authorized value of currency in an economic market the currency note must remain in market if that denominator is in exchange or use and after demonetization of that denominator from regular use it must get extinct value as it represents in economy. It is also expected that all number of legal tenders given in market must be tracked and return for complete life cycle, in case the denominator of any value get damaged and cannot be get exchange then it is the loss for denomination value as well as the production cost of legal tender.With the loss of currency due to physical damage, on the other hand there is a one constant threat which cannot be avoided that is forged currency included in economy. Nowadays every national or Reserve Bank which owns Central authority for issuing currency decided to control circulation of physical tenders by controlling distribution points like Automatic Tailoring Machines (ATM) and distribution mechanisms at unit levels. In current economy currency consists combination of legal tender's that is Bank notes coins which may be common with denominator of Bank notes or separate series, and the new one is electronic medium like Debit or credit Cards. All these modes always have shadow of counter fitting even after continuous technological advancements. The strong Technology used for currency manufacturing gives confidence to issuing authority and general public for having secured and robust currency. This confidence level is directly related to security features and security mechanisms involved in currency manufacturing. For detection of currency counterfeiting or investigation there are many challenges because the first detection or investigation done at public level with visual glance based on general awareness about currency. The reserve Bank of India takes many actions to spread awareness about different security features and characteristics of every denominator at public level by means of publications, advertisement in public interest, press notes and volunteer campaigning by celebrities. Te first investigation at public level is totally depend on circulation and percolation of this information among public at grassroot level for all security features. To control circulation of duplicate currency reserve Bank controls distribution with automatic tailoring machine and Bank sorting machines located at different unit points. These dedicated machines have a combination of image processing, printed pattern recognition and mechanical readings software which acts as machine guidelines for detection of original and duplicate note. The bank has certain machines having image processing software which works on print quality, sharpness of geometrical designs, threshold values for position of elements and dimensions of currency at different denominators. The dedicated software is designed to recognize printing processes and compare print parameters with genuine print quality. It works on target value for all recorded parameters with respect to print quality, ink deposition color and spectral values. Printed images defining printing process by which it is reproduced, mechanisms give detailed reports about substrate

   characteristics, ink characteristics, their performance, and signatures of printing process like offset lithography or intaglio used for currency manufacturing.

   The new development of electronic medium gives option for currency securities like RFID tags which helps to identify, investigate and authenticate the genuine currency also the other electronic mediums are nowadays becoming popular for financial transactions authorized by banking platforms like card payment, UPI payments, Net banking transactions and E-mode of lockers. The use of electronic mediums requires definite amount of financial literacy, resource availability about gadgets, power resources and networking facilities to perform the transactions. The wide spread of currency in India it is hard to control all transactions on E- platform with all conditional challenge. The physical transaction of currency notes will remain the main mode to drive the economy.

   The currency issuing authority always faces the challenge to avoid counterfeiting and detection of counterfeiting before it hammers on economy. The issuing authorities have dedicated manpower which is trained for investigation and detection of counterfeit documents at different levels of forensic investigation. There is always scope for research and development to give strength to security features and secured feeling to public. The security document identification and verification at initial level done at three stages at first glance the visual inspection play than important role for identifying authenticity and genuineness of document by physical touch and optical appearance of colour design interaction of elements at visual level with viewer like microtext, microlines, raised elements the physical sensation of letter or design element printing, OVI printing raise element. The second line of inspection for security documents includes the devices which authenticate documents and genuineness like ultraviolet booth or pen, conductive pens, magnification glass thickness gauge etc. The third line of inspection involves forensic investigation based on scientific methods, confirmed at laboratories. The standard operating procedures are given for testing physical properties of security documents like thickness, tear resistance, coob, folding property. On the other hand the standard procedures and patents are given for identifying security documents on chemical ground. The third line of inspection maybe a destructive which can damage the value of a security document and its use.

5. CHARACTERISTICS OF IDEAL CURRENCY

   1. Strong Design to prevent imaging duplication.

      Designing currency that is extremely difficult to duplicate is a complex and ongoing challenge for central banks and governments around the world. They employ a combination of advanced security features, specialized printing techniques, and materials to make it as challenging as

      possible for counterfeiters to produce fake currency. Designs that cannot be easily duplicated or counterfeited often incorporate a combination of intricate security features, specialized printing techniques, and advanced technologies. These features make it challenging for counterfeiters to replicate the design accurately. Scanners can be used for duplication purposes in various scenarios where you need to create multiple copies of a document, image, or object in a digital format. Here are some common uses of scanners for duplication:

      1. Document Duplication: Scanners are commonly used to duplicate printed documents, such as reports, forms, and letters. You can scan the original document and save it as a digital file (e.g., PDF or image), and then print as many copies as needed from the digital file. This can save time and resources compared to making physical photocopies.

      2. Photograph Duplication: Scanners are useful for duplicating printed photographs. You can scan old family photos or artwork and create multiple digital copies to share with family and friends or for archiving purposes. Digital duplicates can also be easily retouched or edited.

      3. Art and Design Reproduction: Artists and designers often use high-quality scanners to duplicate their artwork or designs for printing or digital distribution. Scanning preserves the details and colors of the original work, ensuring accurate reproduction.

      4. Legal Document Duplication: Law firms and legal professionals use scanners to duplicate legal documents, contracts, and case files for electronic storage and sharing with clients or colleagues.

      5. Fabric or Pattern Dupliation: In the fashion and textile industry, scanners can be used to duplicate fabric patterns, clothing designs, or templates for mass production.

         Scanners play a crucial role in the digital transformation of documents and images. They help individuals and organizations transition from paper-based workflows to digital ones, providing numerous benefits, including improved document management, accessibility, and collaboration. The choice of scanner type and features depends on the specific scanning needs and desired output quality. While using a scanner for duplication, it's essential to consider factors such as the scanner's resolution, color accuracy, and the file format in which the duplicates will be saved. Additionally, you should be aware of copyright and intellectual property laws, ensuring that you have the appropriate rights or permissions to duplicate and distribute the scanned content. Currency designs and security features vary from country to country and are periodically updated to stay ahead of counterfeiting techniques. Central banks also collaborate with law enforcement agencies and international organizations to combat currency counterfeiting. Public education on how to recognize genuine currency and report counterfeit notes is another important aspect of currency security. Counterfeit deterrence remains a continual process,

         and central banks strive to stay ahead of counterfeiters through research, innovation, and the incorporation of advanced security technologies.

   2. Unique Printing Methods

      1. Intaglio Printing: This technique involves the use of engraved plates to create raised ink on the surface of the banknote. Intaglio printing produces a distinctive tactile feel that is difficult to replicate with standard printing methods.

      2. Microprinting: Tiny text or patterns are printed in locations on the banknote where they are barely visible to the naked eye. Counterfeiters struggle to reproduce these minute details accurately.

      3. Color-Shifting Ink: Some banknotes feature ink that changes color when the note is tilted. This effect is created using specialized inks and adds a dynamic and challenging-to-replicate element.

      4. Holography: Holograms or holographic images can be incorporated into the design of banknotes. When viewed from different angles, holographic elements produce shifting, three-dimensional effects that are extremely difficult to duplicate.

      5. Optically Variable Ink: Optically variable ink (OVI) changes color when the banknote is tilted or viewed from different angles. It is a highly secure feature that is challenging for counterfeiters to reproduce accurately.

      6. Security Threads: A thin, embedded security thread runs vertically through the banknote. This thread can be partially visible on the surface and may display text or symbols when held up to the light.

      7. Watermarks: Watermarks are images or patterns embedded into the banknote's paper or substrate during manufacturing. They are visible when the note is held up to the light.

      8. IR-Ink Printing: Infrared (IR) ink printing involves the use of ink that is only visible under infrared light. This feature is difficult to detect or reproduce without specialized equipment.

      9. UV-Reactive Ink: Some banknotes include ink that fluoresces or changes color when exposed to ultraviolet (UV) light. This is a useful feature for quick authentication using UV lamps.

      10. Micro-Optics: Micro-optic features, such as micro- lenses or diffraction gratings, can be integrated into banknote designs to create unique visual effects that are challenging to replicate.

      11. Micro-Embossing: Tiny raised patterns or features are added to the banknote's surface, enhancing its complexity and security.

      12. Transparent Windows: Modern banknotes may incorporate transparent or partially transparent windows with intricate designs or holograms, adding an extra layer of security.

      13. Laser Perforation: Precise laser perforation can be used to create intricate patterns or images on banknotes, which are difficult for counterfeiters to reproduce.

      14. Custom Printing Inks: Unique ink formulations, including specialty inks like magnetic inks, may be used to print specific elements on the banknote.

      15. Specialized Materials: The use of proprietary materials and substrates that are not readily available to counterfeiters is common in currency printing.

      16. Customized Printing Plates: Central banks often use custom-made printing plates with intricate designs and security features that are hard to duplicate.

      17. Machine-Readable Features: Some banknotes incorporate machine-readable elements, such as magnetic ink or security threads, that can be detected by currency counting machines.

   3. Size and Material

      Physical size and material are crucial security features in currency design. They play a significant role in deterring counterfeiting and ensuring the authenticity of banknotes. Here's how size and material contribute to the security of currency:

      1. Non-Standard Size: Distinctive Appearance: Currency notes often have non-standard sizes or dimensions, which make them stand out from regular sheets of paper or other documents. This distinctiveness helps individuals and machines quickly identify currency. Incompatibility with Standard Printers: The non-standard size of currency notes means that standard printers cannot produce them accurately. Counterfeiters would need specialized equipment to replicate the size accurately.

      2. Specialized Material: Unique Substrate: Currency is typically printed on specialized substrates, such as cotton- based paper or polymer materials. These materials are not readily available and are difficult for counterfeiters to obtain. Cotton-based paper is often used because it has a unique texture and durability.

      3. Durability: Currency materials are chosen for their durability to withstand wear and tear in circulation. These materials are engineered to last longer than regular paper, and they can resist damage from folding, tearing, and moisture. Security Features Integration: The material itself can incorporate security features, such as watermarks and security threads. For instance, watermarks are created during the papermaking process by varying the thickness of the paper, making them difficult to reproduce.

      4. Tactile Attributes: Texture and Raised Printing: The texture of currency paper and raised printing techniques used on banknotes create tactile features that can be felt when touched. Counterfeiters often struggle to reproduce these distinctive tactile qualities accurately.

      5. Weight: Distinctive Weight: Currency notes have a unique weight compared to regular paper. This weight is due to the use of specialized materials and printing techniques. Authenticating the weight of a banknote can be an additional security measure.

      6. Size Consistency: Consistent Dimensions: Genuine banknotes are manufactured with consistent and precise dimensions. The size of each denomination is standardized and remains consistent across all notes of the same denomination. Any deviation from these standardized sizes can raise suspicions of counterfeiting.

      7. Material Authentication: UV and IR Features: Some currency materials have UV-reactive or IR-reactive properties that can be detected using specialized equipment. This allows for quick and accurate authentication of banknotes.

   4. Consequences of Counterfeiting or Duplication Duplicate currency, often referred to as counterfeit currency, can have significant negative effects on individuals, businesses, and economies. Counterfeit currency poses various risks and consequences, including:

   1. Loss of Value: Counterfeit currency creates a loss of value for individuals and businesses. When counterfeit money is accepted as genuine, the recipient essentially receives nothing of value in return, leading to financial losses.

   2. Financial Losses for Businesses: Businesses that unknowingly accept counterfeit currency as payment suffer direct financial losses. They are unable to deposit counterfeit money in banks, and it reduces their profitability.

   3. Damage to Reputation: Businesses that frequently accept counterfeit currency may face damage to their reputation. Customers may become hesitant to do business with establishments known for accepting counterfeit money, impacting trust and credibility.

   4. Inflationary Pressure: Counterfeit money injected into the economy can lead to inflationary pressures. When counterfeit currency circulates alongside genuine currency, it can cause the prices of goods and services to rise, eroding the purchasing power of legitimate money.

   5. Reduced Confidence in Currency: Frequent counterfeiting can erode public confidence in the national currency. People may become wary of accepting cash transactions, preferring digital payments or alternative forms of currency.

   6. Increased Costs: Central banks and governments must invest in measures to combat counterfeiting. This includes designing and producing more secure currency, conducting investigations, and implementing anti- counterfeiting measures. These efforts result in increased costs for governments.

   7. Potential Legal Consequences: Handling counterfeit money, even unknowingly, can lead to legal consequences. Individuals and businesses caught with counterfeit currency may face investigation, fines, and even criminal charges.

   8. Impact on Financial Institutions: Financial institutions, such as banks and credit unions, may suffer losses if they inadvertently accept counterfeit money from customers. They must bear the cost of replacing the counterfeit notes with genuine ones.
