Low Level Reader Protocol

LLRP is a "low level" protocol between software and a reader. LLRP provides very fine control over the operation of a single reader. It composed of almost 100 standard commands and provides an interface to low level functionality that is uniform across different reader vendors. Reader vendors don’t have to throw away their existing vendor-specific command language. Instead, many reader vendors support LLRP commands in parallel with their vendor-specific interface. If middleware or application software uses the LLRP interface, portability will be increased.
