The SDK for our RDR products has just been released. It concerns the following devices:
Complete programs are included : for example, a program that monitors a lits of readers, and talk to each one independantly (to set a buzzer, or a LED).

The SDK provides both source code (in C, C# and java) and the compiled binaries.
