 RFID TID Print & Log: POSTEK OX Script Demos

 This is a simple demonstration of how OX Script can be used with RFID 
 applications. The TID is just one of the many data points that can be 
 retrieved and can then be easily written to databases, logged inside 
 the printer, used to fetch specific data from databases, or help encrypts 
 the data.
