When a 900 MHz tag is attached to a storage server, is there any possibility that reading the tag could cause an error in the server—for instance, killing service or corrupting data?
Passive UHF RFID readers use relatively low levels of RF energy to power up and communicate with passive tags. There is not enough energy to have any impact on storage servers or any kind of computer device. To my knowledge, there has never been any incident reported of an RFID system affecting the performance of servers or laptop PCs, and tags have been placed on hundreds of thousands of such devices during the past few years.
I hope this answers your question, and I look forward to seeing you at RFID Journal LIVE! in May.
