Chipless second generation (Glossary of Printed Electronic terms)

The second stage of chipless RFID, which can lead to sales of billions to trillions yearly, is its use in open RFID systems i.e. where many service providers are involved with any one system. This stage has been delayed not by lack of suitable technology but by the fact that the chipless proponents involved were undercapitalised, let the standards be written around more expensive chip tags and were often poorly managed, chasing the wrong opportunities. The standards in question were the operational standards defining frequencies, signalling protocols etc. Chipless labels have no problem with the numbering conventions, though versions with more than 24 bits have tended to be stuck in the laboratory with the exception of SAW tags.
