Interfacing RFID to 8051microcontroller

praveen July 29, 2015 1 Comment
Interfacing RFID  to 8051 . RFID or Radio Frequency Identification is a method in which electromagnetic waves are used for transmitting data for the purpose of identifying tags attached to objects. An RFID system consists of a transmitter (tag) and a reader.The tag is encrypted with a unique code and the reader scans this code for the identification purpose. The tags are generally of two types: active and passive. Active tags have a battery fitted to it and it transmits the unique...
