Unless RFID tags are already built into the boxes that you use you will need to add an RFID tag to existing boxes. These are the so-called smart boxes that will begin to be available sometime around 2015.
Many people have discovered that spending millions of dollars on an automated tagging equipment for packaging lines is an investment that will never payback before they become obsolete (around 2015).
Others have considered running dual inventories, but that requires at least a doubling of warehouse floor space and inventories as mandates scale out over then next few years.
ADASA customers have learned that the best way to ramp up tagging operations during these times is to integrate tagging into their existing order picking processes. This allows you to keep your existing warehouse operations intact and add a highly efficient tag commissioning step for mandate compliance.
If your use case is to tag automobile windshields, or fixed assets then you already know that you have to write data to the RFID tag at that location. ADASA performs that task flawlessly, writing the right data to the right tag on the spot. The physics of UHF RFID tags is such that the programming fields have to be very carefully controlled to prevent more than one tag from being programmed at any one time. ADASA has perfected this process and incorporated it into each and every mobile tag encoder.
