ACS - ACR1251U

The ACR1251U is the second-generation NFC Reader from ACS, which offers advanced features such as firmware upgradeability, a SAM (Secure Access Module) slot, and support for NFC tags and devices. It is ideal for contactless applications with added security functions. Through the SAM, key diversification and mutual authentication are made possible, restricting the exposure of keys and limiting the possibility of keys being stolen, providing a high level of security in contactless operations.

ACR1251U is suitable for any contactless smart card application such as personal identity verification, network login, online banking, and micropayment. With enhanced NFC features, ACR1251U-A1 is also ideal for non-conventional NFC applications like Smart Posters for advertising and marketing, and communication with most-NFC enabled mobile phones.

Furthermore, ACR1251U is PC/SC-compliant, allowing interoperability across different applications and platforms. ACR1251U also supports remote post-deployment firmware update, which eliminates the need for additional hardware modification. With its compact size, trendy design and rich features, ACR1251U enables you to fully enjoy the convenience of using NFC applications.
