The RC522 RFID Reader/Writer Module operates at 13.56 MHz, which is the standard frequency for MIFARE Classic cards and ISO 14443 tags used in access control and attendance systems worldwide. The 50mm operating distance means a card held near the module triggers a read — no tap or swipe contact required. The rfid module connects to microcontrollers via SPI at up to 10 Mbit/s data rate. At 3.3V supply with 13–26mA operating current and under 80 µA in sleep mode.
The rc522 rfid reader suits battery-powered access systems running for extended periods. The rfid reader module can also write data back to writable MIFARE cards — storing custom IDs, access levels, or user data directly on the card rather than only in the system database. Idle current drops to 10–13mA when no card is present, keeping power consumption low between reads.
The rc522 rfid reader writer arduino combination is one of the most documented beginner projects available — the MFRC522 Arduino library installs in one click and the wiring uses six SPI pins. The rfid reader writer module ships with one RFID card and one tag, giving two different form factors to test immediately. Available from StemVolt.
