![]() ![]() The range is typically 100 feet or more.Data can be read or write from the cards as they consists of EEPROM.RFID Cards can be either active type or passive type. ![]() RFID Card or Tag consists of an antenna and an IC for storing the data. It radiates a 125 KHz signal through its antenna and hence a similar frequency based RFID Card must be used. The RFID Reader module used in this project is EM – 18. ![]() RFID readers can read and/or write data in to the RFID cards (depending on the type of the card). A simple RFID reader consists of an antenna, demodulator, data decoder unit and some filters. RFID Reader Modules are basically radio frequency transceiver (transmitter and receiver). Hence, it contains two components: RFID Cards or Tags and RFID Reader.
