The United Nations currently coordinates international postal services through the Universal Postal Union, but it feels that the speed of deliveries could be increased with the use of RFID.
Unlike private delivery services such as FedEx, regular postal delivery is not operated by a single organization. Consumers buy stamps in one country that have to get a piece of mail into another country and through the domestic mail system there to a particular destination. The UPU sets quality-of-service rules for how long that should take, as well as standard origination and termination fees for countries to settle the cost of getting the mail where it’s going.
So far, the UPU has monitored letter delivery by sending special test letters. Independent analysts record the departure and arrival of these test letters, but at the gateway offices where letters leave and enter countries, postal workers themselves record the time. That leaves the process open to manipulation, said Akio Mayiji, quality of service coordinator at the UPU.
The RFID system instead will use tags hidden inside envelopes, which will be read automatically as they pass through RFID portals at the international gateway offices. Reva Systems’ TAP (Tag Acquisition Processor) servers will collect the letters’ unique tracking numbers and pass them on to be correlated into delivery reports. The UPU wants countries to pay each other based on the quality of service their letters receive, and more detailed measurement will help it do so, Miyaji said.
RFID is already used to monitor mail in some developed countries, but the systems they have deployed use “semi-active” tags that cost US$20 each. A relatively new global standard for RFID, called Gen2, allowed the UPU to introduce passive-tag systems that cost far less: Each tag only costs about US$0.30, and the UPU considers them disposable. The lower cost should make RFID accessible to all of the UPU’s 191 member countries. The scope of quality testing can also be expanded, so tens of thousands of test letters are moving through the system at any time.
21 countries will be testing the new tags, including India, South Korea, Switzerland and Togo. Countries with the older RFID tags will also be participating. These include Mexico, Norway, and Saudi Arabia.
