Recently I bought a set of Arduino-compatible components including RFID sensor (RC522).After short search I've found good tutorial telling how to use this sensor, downloaded a library and connected sensor to my Arduino (be careful there is a typo in original blog post):
- MOSI: Pin 11
- MISO: Pin 12
- SCK: Pin 13
- SS: Pin 10
- RST: Pin 5
- GND: Gnd
- VCC: 3V3
