The Value of an HF EPC Standard
Although GS1's ratification of a high-frequency standard did not generate a lot of buzz, it is good news for end users.
For these reasons, some companies might opt to use HF tags on individual items, and UHF tags on pallets and cases. Since tags based on the new HF EPC standard will employ the same data structures and reader commands as the UHF standard, you could use a single reader with a UHF and HF module to communicate with both tag types.
HF tags based on the new protocol will have a transponder ID (TID), an EPC and user memory option, and a similar command set to UHF tags. If, for example, your company has developed a system for saving information in user memory regarding which store an item should be shipped to, you can employ the same system with both UHF and HF tags.
Will the additional features be enough to encourage adoption of the EPC HF standard? It's difficult to say. It will depend on whether vendors embrace and promote the standard, and on whether any large end users adopt it. My guess is that the HF standard might catch on over time as pharmaceutical manufacturers and other end users deploy UHF systems at the pallet and case levels, and then eventually replace 2-D bar codes with RFID tags at the item level.
Regardless of how quickly or slowly the standard catches on, it offers another choice for end users—and that's good news.
