ADASA Inc. develops intellectual property and solutions using radio frequency identification (RFID). Brick and mortar retailers are striving to compete with online retailers like Amazon for customers, competitive prices, and same-day delivery. To win they must use in-store inventory to fulfill online orders. That requires efficient and accurate inventory counts, preferably on a daily basis. RFID-reading flying robots that cruise stores at night without incurring errors or labor costs. All of this requires RFID tags with globally unique serial numbers that are based on GS1 standards; which is entirely based on the ADASA ‘198 patent.
