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. ACR122U Card Reader Beware of the many bogus products, of questionable quality and reliability, being offered under the ACR122U product name that aren’t genuine ACS readers – these should be avoided. The ACS products listed below come from official and certified channels Smart Cards & Smart Card Operating Systems ACS offers a line of mobile smart card readers to work in conjunction with most tablets and smartphones on the market Smart card modules 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.

Unfortunately (it took me some time to figure it out), the data managed by one thread can not directly be accessed by another thread. So, I use a little workaround. Available in the following programming languages: Java, Delphi 7, Visual Basic 6, Visual C++ 6, Visual C++ 2005 (x64), Visual C# 2005 and Visual Basic .Net 2005

These smart card reader modules are designed to be integrated into embedded systems. 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.

In our original code, it is an object created on the class ACR122U (be aware of the casing). We will make our own class, derived from this class, in which we will add a property in which we will store the data. For purposes of demonstration, the ID will be used.
