RFID Based Attendance System Circuit Working Source Code

RFID Based Attendance System – Circuit, Working, Source Code

Attendance in colleges is generally paper based which may sometimes cause errors. Taking attendance manually consumes more time. So the proposed attendance system uses RFID technology to take attendance. In this system, each student is issued an RFID tag. Controlling unit is in the institute. Whenever the card is placed near the reader, it will …

RFID with PIC

How to interface RFID with PIC18F4550 Microcontroller

RFID (Radio Frequency Identification and Detection) is widely used everywhere from highly secured defense laboratories to school attendance system. By employing RFID, much secured entry systems can be developed without incurring huge costs. These are the reasons of excessive use of RFID technology. In this article, interfacing of an RFID reader module has been explained …

Toward hack-proof RFID chips

Toward hack-proof RFID chips

MIT researchers have developed a new type of radio frequency identification (RFID) chip that is extremely difficult to hack. If such chips were widely adopted, it could mean that an identity thief couldn’t steal your credit card number or key card information by sitting next to you at a cafĂ©, and high-tech burglars couldn’t swipe …

Ultralow-power RFID transponder chip in thin-film transistor technology on plastic

Ultralow-power RFID transponder chip in thin-film transistor technology on plastic

At this week’s IEDM 2014, held in San Francisco, California, nanoelectronics research center imec demonstrated an ultra-low power RFID transponder chip. Operating at sub 1V voltage and realized in thin-film transistor technology (TFTs) on plastic film, the chip paves the way for universal sensing applications, such as item level RFID tagging, body area networks (BAN) …
