ACR122L VisualVantage Serial NFC Reader

The ACR122L is an LCD-equipped PC-Linked NFC Contactless Reader with RS232 serial interface.

ACR122L is an LCD-equipped PC-Linked NFC Contactless Reader with RS232 serial interface.  ACR122L is developed for 13.56 MHz RFID technology and the ISO14443 Type A and B cards, Mifare, FeliCa and all 4 types of NFC tags.

ACR122L is a plug-and-play device that does not require any driver installation. It comes with 4 LEDs, a buzzer and an LCD, which both provide users with a clear indication of the reader's status. The 2-line graphic LCD has multiple language support. Moreover, it is equipped with three built-in SAM slots for enhanced security in contactless operations.

The reader can read and write more quickly and efficiently by using up to 424 Kbps of tag access. It also has a proximity operating distance of up to 50 mm, depending on the type of tag in use. Further, its built-in anti-collision feature and direct card type polling commands ensure a smooth operation, allowing the device to access only one card, even in cases where multiple cards are present and detectable.

Typical applications of ACR122L include e-payment, loyalty programs and access control.
