How Converters Can Make RFID Labels

Such problems are opportunities of course, with companies such as Trierenberg Holdings seeking to be first to print HF antennas at high speed. Do not believe the more strident enthusiasts for UHF RFID who argue that it will be used for almost everything. Indeed, in contrast to HF, it will always have serious limitations. There will never be a single signalling protocol, frequency, power level, or bandwidth for UHF RFID across the world. Vested interests in the military, mobile phone ,and other industries will see to that. Near-field UHF for short range and small items has yet to be sold in volume and it has limitations and challenges to offset its undeniably cheap antenna construction.
