The Universal Postal Union, the intergovernmental network of national postal services, recently announced global implementation of a new tracking program for international letter mail as part of its Global Monitoring System. It hopes to enable post services around the world to improve delivery quality with improved metrics. The Tag Acquisition Processor (TAP) product, provided by mailing technology company Reva Systems, allows the UPU to track delivery times for every mail piece sent from one country to another through RFID tags automatically, rather than requiring manual barcode scans or active tracking.
