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.

NFC Chip Types
An NFC tag has an NFC chip inside of it which performs the NFC interactions. There are several NFC chip types available and the choice of which NFC chip type to use is important. Each NFC chip has its own characteristics, features and cost. If you are not sure which NFC chip to use, our recommendation is to get a couple of each type to test with. The NXP NTAG series is typically what customers use. The NXP NTAG series comes in a variety of data capacity sizes and they offer the best device compatibility, speed, availability and cost.
