Polish Post Completes RFID Testing at Distribution Center

ProxiGroup's UHF RFID system may next be installed across all distribution sites, in order to make parcel shipping more efficient, as well as boost customer satisfaction.

When a parcel was received for shipping, staff members at the receiving area could simply scan the bar code that came with that package (from the digital order), and the SATO printer could use the ProxiGroup software to encode the UPC with the EPC number. The label was then attachecd to the parcel.

Once the parcel began moving throughout the facility, the data was collected without requiring a bar-code scan. However, Polish Post also scanned bar codes for redundancy purposes. Those scans, Sękowska says, could cause delays—sometimes requiring an hour to scan each 200 parcels, as well as the time for the data to be uploaded. The RFID reads, on the other hand, could be accomplished within seconds.

Initially, the technology company delivered the parcels in open carts, but Polish Post indicated that it wanted to test the RFID tag reads in metal-enclosed cages. Therefore, it tested them that way so as to make the tag reads more challenging. The tag read rate was higher than 98 percent in the metal cages, Sękowska says. As the tagged parcels moved throughout the facility along with the other untagged parcels, the tag IDs were read at each zone.

The ProxiTrak system collected a total of 60,000 read points during a span of two weeks. The postal company could then view the parcels' movements around the facility. The software showed an icon indicating the location of any specific parcel, and users could view a line tracing the history of its movement. In this way, they could view not only where parcels were in the distribution process, but when bottlenecks occurred, or if a parcel was potentially being routed incorrectly.
