The ACS ACR122S is a serial NFC reader and writer that comes with a built-in ISO 7816 SAM slot for enhanced security, plus a buzzer and two LEDs for rich user interaction. The reader can also read and write faster and more efficiently by making use of up to 424 Kbps for tag access. The proximity operating distance of ACR122S is up to 5 cm, depending on the type of tag in use. The ACR122S uses a serial port for communication which allows for greater flexibility of device integration. For example, a vending machine, parking meter or retail self-service terminal may need direct Serial (RS232) communication with the NFC reader. No device driver is required and an available USB port is required for power supply only.
