ACR122U NFC Contactless Smart Card Reader Software Development Kit
Software Development Kits

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.
