ACR123U
Intelligent Contactless Reader

The ACR123U is the USB version of the ACR123S, a cost-effective, flexible and intelligent contactless reader. It can be integrated to existing (Point-of-Sale) terminals or cash registers, to offer the convenience of a cashless payment system. The ACR123U speeds up movement in checkout counters, by enabling customers to complete payments by simply tapping their cards.

The ACR123U is equipped with a large graphical LCD that allows merchants to display messages, as well as a large tapping area with backlight, which guides customers in carrying out their payment transactions. Developed based on 13.56 MHz contactless (RFID) technology, it supports any contactless card following the ISO 14443-4 standard. It is also equipped with a large graphical LCD, as well as a large user-controllable tapping area with backlight.
