This month's SD Times included two little RFID articles regarding the work of Oracle and iBOLT with huge implications.
iBOLT's (IBM strategic partner/love fest) RFID can track as much as 1MB of XML. One common example, the RFID tags becomes a live record of what's happening with the shipment.
Oracle's Sensor-Based Services (supposedly bundled with the next version of their Application Server) contains a Compliance Package and a Pilot Kit to meet U.S. Dept. of Defense, Wal-Mart, European supermarket chain Metro, and British supermarket chain Tesco... All of which have mandated that their business partners replace barcode systems with RFID.
Oh yeah... GlobeRanger (Microsoft strategic partner/love fest) provides RFID software built on the .NET Framework.
