Furthermore the intelligent digital button security systems are mounted to the refrigeration units in indoor and outdoor environments that can even perform operations for the various data logging tasks in the digital intelligent button.

1. Introduction

   The intelligent button device is a durable container chip which makes up-to-date information electronically, which is stored in a key with help of the key objects which is accessible anywhere. The durable of the intelligent button key micro can package is the highly resistant module which protects the device from the environmental hazards like dirt, moisture and the shocks. It is compact as like a small coin shaped button profile and is self- aligning with the mating receptacles in the system which is allowing the device to be used easily in any digital locking systems by the

   operators. Its accessories will permit the device to be mounted on the plastic key tabs with a button shaped device, in the photo Id badges, in the printed circuit boards of electronic devices and in any smooth surface of the object which is compatible. The applications can be included in the access control system which is in the work in the progress of the tracking system of a device, the security device tool management and also the digital security inventory control system.

   • Intelligent button device varieties include as follows:

     Digital secure Address Only, That Guaranteed with the unique 128-bit serial numbers in the system i.e., address of the ibutton & ROM id of the ibutton, it is ideal for getting access control to the route verification of the various digital key applications. The models will be of different types that the data can be stored in the NVRAM of the ibutton device, EPROM with the write at once read many and flashing with EEPROM.

     The different models range from 31K bits to the 128K bits. The Real Time Clock also supplies the unique way to maintain the timings in the digital applications such as digital calendar, digital stopwatch, digital meters and digital Time Stamps.

     The secure data connection can be protected with the help of the algorithm called SHA-1 Secure Hash Algorithm or with the password protection depending on the various level of the security is required.

2. Intelligent Button Components

   An Intelligent Button device uses the stainless steel for making the device which acts as an electronic communication interface device system and is resistant to the weather and other environment conditions. Each can have the digital data contact with the source called lid and the ground contact with the device is also known as the base. The each of the contacts is connected to the unique silicon chip located inside the steel interface. The lid is only the top of the base forms in the device of the different sides and the bottom of the device button also includes the flange in order to simplify the attaching of the digital button to adjust the digital button about anything. The two different contacts are also separated by the polypropylene grommet in the silicon chip device.

   • 1-Wire Interface

     By simplifying touch of the intelligent button device to the two different contacts as described above, you can communicate within and with through the 1-Wire protocol and the interface. The 1-Wire protocol and interface has the two- way communication speeds that is standard speed mode at 28kbps and the over drive speed mode at the 156kbps.

   • Intelligent Button Address

     Each intelligent button device has the unique and the unalterable address in the form of laser etched code onto its microchip inside the device. The address looks like e.g. 8200000095A33878 can be used as a key for the identifier for each ibutton device.

3. Intelligent Button Devices

   The intelligent Button devices are very small and durably packaged with various modules with the globally unique digital key addresses. It offers a range of the functions in order to deliver the records and the record data values where the other products cannot do it, such as the harsh environments. Our intelligent Button products will lower the cost of the ownership in various cost reducing methods for the temperature and the humidity of the digital data logging, digital

   access control, asset digital tracking and the electronic cash or eCash transactions. The connected devices are also available for the various systems that requires the near field communications with NFC and RFID compatibility in the system.

4. Asset Management

   Intelligent Button devices bring the unparalleled durable to asset the digital data management applications to even in the harsh industrial and the harsh outdoor environments.

   • Asset Management Tag

   It provides a simple and the secure way of identifying the assets of each digital intelligent button device has a unique 128-bit address that can be used for the electronic generated serial number that can be never duplicated by others. Additionally, the on-board memory is up to 64kB gives the assets to customize and own the personalized database. This current database enables the storage of the unique information about the each asset is integrating and including the maintenance records of the inventory management in the information that can be permanently affixed to the each asset which is defined.

5. Access Control Key

   Intelligent Buttons requires a physical or electrical connection to whatever it is writing the data or reading the data. However, the novel digital communication scheme is also known as 1-Wire interface which reduces the number of electrical contact points in the system to just one with ground reference. Only single conductor for the both power and the data communications is all which is needed. Devices that always read data and write data to the Intelligent Buttons seal all the electrical components inside the chip and then expose the only two electrical contact points in the chip and then get separated by the wide gap.

   • With the connection are simplified to get very durable to the dust and the moisture immune that probes the interface to the most surfaces.

   • An intelligent Button reader draws the virtually the no power in the standby mode and which is less than 3mA during the communication.

   • For the battery powered devices such as the electronic door locks etc., Reading the intelligent Buttons unique address that takes no more than 15ms.

   • A typcal intelligent Button lock can also operate more than 60,000 openings in single unlock procedure on a set of four AA batteries for the device.

   • Memory with Time Dependent Access

     The intelligent Button has the on board real-time clock that can be armed in order to expire at a future date and the time. This also feature that can be used to disable the access to the data inside the intelligent Button. Access can also be denied which is based on the elapsed time in a device or chip or number of accesses in the chip.

   • Memory with Password Protected Access

     When the user or customer want to a limit access to the secure data, an intelligent Button can also require the local host to know the local password for any read data or write data operation. The intelligent button has three service data pages in the chip. Each has 58-byte page and it has its own 128-bit access to the password and the service ID. The intelligent button has 38kB of EEPROM memory in the chip. Access to internal memory can also be password protected with the different

     unique passwords for the read only and the full access for the iButton.
