LLRP (Low Level Reader Protocol) is an interface protocol used to facilitate the communication between software and the hardware reader. It was designed as a means for developers to have a standard method to access multiple readers from different manufacturers, without having to custom develop for each one. ClearStream RFID employs the use of LLRP to be compatible with as many hardware systems as possible. As long as your hardware reader supports LLRP, it should be compatible with ClearStream RFID.
