RFID-RC522 RF IC Card Reader Sensor Module
RFID (radio frequency identification) systems use data strings stored inside RFID tags or transponders) to uniquely identify people or objects when they are scanned by an RFID reader. Because passive tags require a strong RF field to operate, their effective range is limited to an area in close proximity to the RFID reader. Perfect for use in various electronics projects in India, RFID RC522 13.56 MHZ Reader/Writer SPI S50 Card and Keychain ensures reliability and performance. Ideal for various electronics projects, RFID RC522 13.56 MHZ Reader/Writer SPI S50 Card and Keychain offers quality and performance.
