ACR1252U
USB NFC Reader III (NFC Forum Certified Reader)

The ACR1252U USB NFC Reader III is an NFC Forum-certified PC-linked reader, developed based on 13.56Mhz contactless technology. It has a SAM (Secure Access Module) slot which can be used together with a SAM card for key diversification and mutual  authentication, providing high-level security in contactless transactions. Post-deployment firmware upgrade is also supported, eliminating the need for additional hardware modification.

ACR1252U is capable of the three modes of NFC, namely: card reader/writer, card emulation and peer-to-peer communication. It supports ISO 14443 Type A and B cards, MIFARE®, FeliCa, and ISO 18092–compliant NFC tags. It also supports other NFC devices with an access speed of up to 424 Kbps and proximity operating distance of up to 50mm (depending on tag type used).

Compliant with both CCID and PC/SC, this plug-and-play USB NFC device allows interoperability with different devices and applications. It is thus ideal for unconventional marketing and advertising applications like smart posters.

The ACR1252U comes with an optional stand to hold the smart card reader at an optimal angle, so that users can tap contactless cards or NFC-enabled devices onto the ACR1252U with ease. For more information, click here to download the brochure of this special accessory.

There are two connector type available for order now, USB Type-A (ACR1252U-M1) & USB Type-C (ACR1252U-MF).

 

Fido Support

The ACR1252U USB NFC Reader III also supports FIDO (Fast IDentity Online) authentication protocols, making it compatible with FIDO-enabled devices such as PocketKey and YubiKey. This enables secure, passwordless login and strong 2FA authentication for online services. By leveraging the NFC capabilities of the ACR1252U, users can conveniently authenticate themselves by simply tapping their FIDO-enabled NFC device on the reader.


Integrating FIDO support enhances the security of online transactions and access control systems, making the ACR1252U an ideal choice for e-Government, banking, e-healthcare, network security, and other applications requiring high-level security.
