MFRC522 RFID Reader-Writer Leave a comment

RFID is the abbreviation of Radio frequency identification. RFID modules use electromagnetic fields to transfer data between card and the reader.

Different tags are attached to objects and when we place that object in front of the reader, the reader reads that tags.Another benefit of RFID is that it doesn’t require to be in a line of sight to get detected.  As in barcode, the reader has to be in the line of sight to the tag and then it can scan but in RFID there’s no such restriction.
