ACR122U

USB NFC Reader

The ACR122 is specially developed based on 13.56MHz contactless smart card (RFID) technology, supporting not only Mifare®, ISO 14443 A and B cards but also NFC and FeliCa contactless technologies.

About ACR122U

The ACR122U NFC Reader is a PC-linked contactless smart card reader/writer developed based on the 13.56 MHz Contactless (RFID) Technology. Compliant with the ISO/IEC18092 standard for Near Field Communication (NFC), it supports not only Mifare® and ISO 14443 A and B cards but also all four types of NFC tags.

ACR122U is compliant with both CCID and PC/SC. Thus, it is a plug-and-play USB device allowing interoperability with different devices and applications. With an access speed of up to 424 kbps and a full USB speed of up to 12 Mbps, ACR122U can also read and write more quickly and efficiently. The proximity operating distance of ACR122U is up to 5 cm, depending on the type of contactless tag in use.

In order to increase the security level, ACR122U can be integrated with an ISO 7816-3 SAM slot. Furthermore, the ACR122U NFC Reader is available in module form, permitting easy integration into bigger machines, such as POS terminals, physical access systems and vending machines.

The ACR122U NFC Reader is ideal for both secure personal identity verification and online micro-payment transactions. Other applications of the ACR122U include access control, e-payment, e-ticketing for events and mass transit, toll road fare collection and network authentication.

ACR122U NFC Contactless Smart Card Reader Software Development Kit

The ACR122U NFC reader is the world’s first NFC reader compliant with the CCID specification. The ACR122U and its token version, ACR122T, are designed to support not only Mifare® and ISO 14443 Type A and B cards, but also FeliCa and NFC tags.

Comprehensive SDK - ACS provides a comprehensive collection of sample codes for device and contactless card programming using the latest versions of powerful object-oriented programming languages namely, Java, Delphi 7, Visual Basic 6, Visual C++ 6, Visual C++ 2005 (x64), Visual C# 2005 and Visual Basic .Net 2005. The extensive set of development tools and reference materials in the SDK allows one to use the ACR122U/ T for RFID-based solutions, such as e-payment, access control, personal identity verification, mass transit and toll road fare collection. With this complete ACR122 NFC Card Reader Software Development Kit, users can optimize the use of ACR122U/T for their contactless and NFC applications.

Peer-to-Peer Capability - As an additional SDK feature, ACS provides users with the option to experience a simulation of a real-world NFC peer-to-peer application - Smart Poster application. Two ACR122U/T NFC readers are needed for the peer-to-peer demo since one ACR122U/T acts as the smart card poster and the other one as the NFC device. The demo shows the capability of these two devices to exchange data via the peer-to-peer operating mode.

The development kit is priced at only US$149.
