The ACR1281U-C2 Card UID Reader is a contactless card reader that automatically and efficiently retrieves the Unique Identifier (UID) number of any ISO 14443 Parts 1-4 Type A and B compliant contactless card.

When a contactless card, such as a MIFARE card, is presented, the ACR1281U-C2 retrieves the card's UID and automatically returns it to the PC. The reader allows for the direct output of the UID into any editor, such as Notepad, MS Excel, MS Word, etc. With the UID, cardholders can be accurately identified in various applications such as identity verification, time tracking, and access control. The ACR1281U-C2 also features an anti-collision function that ensures only one card is accessed when multiple cards are presented simultaneously.

Since the ACR1281U-C2 Card UID Reader complies with the HID (Human Interface Device) standard, issues with driver installation during integration into PC environments are minimized. It supports most operating systems, including Microsoft Windows, Linux, and other embedded systems.
