It's really not such a far-fetched idea. For years, hotels have had a sensor-based application that records when someone removes a product from the mini bar.
Madison, Wis.-based Terso Solutions introduced a UHF Gen 2 RFID medical cabinet Wednesday that manages inventory of high-value products like orthopedic supplies, cardiovascular products, reagents, Class II pharmaceuticals, specimens and bio-samples, as well as products that have environmental restrictions.
This storage system combines RFID, secure access control technologies and the Internet for item level inventory management. System hardware, software and services like technical support complete the package. Once the cabinet door is closed, the RFID system records the items that were removed and communicates the information back to the hosted database.
