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 Interfacing with PIC Microcontroller

RFID stands for Radio Frequency Identification. RFID module can read or write small amount of data into a Passive RFID tag, which can be used in identification process in various systems like Attendance system, security system, voting system etc. RFID is very convenient and easy technology. To read the Passive RFID cards and tag, we need a microcontroller with UART …

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) …
