ACR122L VisualVantage Serial NFC with LCD

ACR122L is a contactless NFC reader with serial interface and LCD. It was developed based on 13.56 MHz RFID technology and the ISO / IEC 18092 NFC standard and supports ISO 14443 type A and B cards, MIFARE and all four types of NFC tags.

ACR122L is a plug-and-play device that requires no driver installation. It comes with 4 LEDs, a buzzer and an LCD that give the user a clear indication of the status of the reader. The 2-line graphic LCD supports multiple languages, including language support for Chinese, English, Japanese and some European languages. The graphic LCD enables interactive operation, such as scrolling up and down, left and right, etc. In addition, it is equipped with three integrated SAM slots for increased security in contactless operation.

The reader can read and write faster and more efficiently by using up to 424 Kbit/s tag access. Depending on the type of tag used, it also has a distance of up to 50 mm. The integrated anti-collision function and direct card type polling commands ensure smooth operation, allowing the device to access just one card even when multiple cards are present and detectable.

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