ARM Based RFID Attendance System Radio-frequency identification (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almostparallel reading of tags. RFID can be used in many applications. A tag can be affixed to any object and used to track and manage inventory, assets, people, etc. For example, it can be affixed to cars, computer equipment, books, mobile phones, etc. The Healthcare industry has used RFID to reduce counting, looking for things and auditing items. Many financial institutions use RFID to track key assets and automate compliance. Also with recent advances in social media RFID is being used to tie the physical world with the virtual world. RFID in Social Media first came to light in 2010 with Facebook's annual conference. RFID is a superior and more efficient way of identifying objects than manual system or use of bar code systems that have been in use since the 1970s. Furthermore, passive RFID tags (those without a battery) can be read if passed within close enough proximity to an RFID reader. It is not necessary to "show" the tag to the reader device, as with a bar code. In other words it does not require line of sight to "see" an RFID tag, the tag can be read inside a case, carton, box or other container, and unlike barcodes RFID tags can be read hundreds at a time. Bar codes can only be read one at a time. In 2011, the cost of passive tags started at $0.05 each and special tags, meant to be mounted on metal or withstand gamma sterilization, can go up to $5. Active tags for tracking containers, medical assets, or monitoring environmental conditions in data centers all start at $50 and can go up over $100 each. Battery Assisted Passive (BAP) tags are in the $3–10 range and also have sensor capability like temperature and humidity ARM7 is a generation of ARM processor designs. This generation introduced the Thumb 16bit instruction set providing improved code density compared to previous designs. The most widely used ARM7 designs implement the ARMv4T architecture, but some implement ARMv3 or ARMv5TEJ. All these designs use a Von Neumann architecture, thus the few versions comprising a cache do not separate data and instruction caches. RFID is most widely used system we mostly use it will computer or embedded devices. Use of RFID system reduced time to action and keeps data in more proper way as we needed. We have also decided to implement an attendance system that is based on RFID technology but this system will no need to any PC to store data all information will be stored upon I2C memory. The system will be based upon ARM technology which works instead of a personal computers right here.

Advantages of RFID Technology RFID technology has a number of advantages. • RFID tags are very simple to install/inject inside the body of animals, thus helping to keep a track on them. This is useful in animal husbandry and on poultry farms. The installed RFID tags give information about the age, vaccinations and health of the animals. • RFID technology is better than bar codes as it cannot be easily replicated and therefore, it increases the security of the product. •

Supply chain management forms the major part of retail business and RFID systems play a key role by managing updates of stocks, transportation and logistics of the product.

Barcode scanners have repeatedly failed in providing security to gems and jeweleries in shops. But nowadays, RFID tags are placed inside jewelry items and an alarm is installed at the exit doors.

The RFID tags can store data up to 2 KB whereas, the bar code has the ability to read just 10-12 digits.

Disadvantages of RFID Technology The RFID technology, though very beneficial, is expensive to install. Small and medium scale enterprises find it costly to use it in their firms and offices. • Interference has been observed if devices such as forklifts and walkie-talkies are in the vicinity of the distribution centers. The presence of mobile phone towers has been found to interfere with RFID radio waves. Wal-Mart, the retail sector giant, has installed billions of RFID tags in their products throughout the world and they have encountered such problems. • RFID technology has been referred to as invasive technology. Consumers are apprehensive about their privacy when they purchase products with RFID tags. Once the radio chips are installed in the product, the customer can be tracked and his Abs Computers - Courses – Projects – Implant Training for Diploma - BE - ME - B.Tech - M.

personal information can be collected by the RFID reader. However, many stores have a facility that deactivates the RFID tags after the product has been purchased.
