CARD AND STICKERS SYSTEM USING UHF RFID NFC IN PAKISTAN

Several technologies like Biometric, RFID, NFC, etc can be used to simplify and improve the attendance system, since user identification is the most important aspect that needs to be handled cautiously in this type of applications. In this work we propose a web based attendance system using Near Field Communication (NFC) technology. NFC is a new, short range, high frequency, low bandwidth, and wireless communication technology. NFC communication is activated by touching two NFC enabled devices together, or bringing them into close range. The range is usually few centimeters, and it operates at the frequency of MHz. The maximum data transfer rate is 424kbit/s. NFC is based on Radio frequency Identification (RFID) thus its communication involves initiator and a target, the initiator actively generates a Radio Frequency (RF) field that can be used as a signal to power a passive target. The initiator (active) has its own internal power that can be used to power the ICs that generate the outgoing signal; while the target (passive) has only ICs with no internal power, which makes it to be in different forms like tags, stickers or cards.
