Palm PR, Intertraff number plate recognition software, runs on any Microsoft Windows 2003 PDA. Through a Compact Flash Camera, Palm PR analyses continuously the live picture looking for number plates. Once a vehicle plate is detected, the number is recognized using a series of complex template-matching algorithms and a full image picture of the vehicle and its plate patch is stored on the SD memory card. The reading results are also compared with the local database to find out if the vehicle is stolen, authorized, etc.

PalmPR does not need a starting trigger to attempt to find a number plate in one single picture. On the contrary it simply analyses the Compact Flash Camera video signal at the speed of 5 frames per second and if a number plate is found, PlamPR recognizes it in 0,5 seconds.
