Will Class 1 Gen 2 become the dominant EPC UHF standard?

yRFID » RFID FAQs » Electronic Product Code »

The arrival of Gen 2 does not signal the retirement or obsolescence of other RFID protocols. Gen 1 tags will likely be used through 2007 until existing supplies are exhausted. And RFID technologies are very likely to rapidly evolve into future generations in the coming years. In addition, different protocol standards can be used for different applications, just as numerous bar code symbologies are used today. Organizations should build their RFID infrastructure with multi-protocol printer/encoders and interrogators. Multi-protocol equipment provides investment protection and simplifies upgrades because it can simultaneously support different RFID standards and tag types.
