## Description

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.

Review: NFC scanner works great - After a few of these NFC devices this one actually works, with PC and Mac intel and silicon. Make sure you are on a tech level to change the mode to scan the cards and program them.
Review: Good for FIDO authentication - Works perfectly for my use case: authenticating to websites running in Chrome on Windows without having to plug my YubiKey into a USB port. This worked out of the box with no configuration/special drivers. Has an LED which constantly flashes while the device is plugged in for some reason.
