I’d like to connect a reader to a computer as small as a cellphone, and I need it to provide reading and writing functions. Does such a reader already exist, or would I need to create one?
I don’t think it makes sense to connect a computer to a passive ultrahigh-frequency (UHF) RFID reader. Most fixed and handheld readers are computers and have the ability to filter data that is read, as well as write information to tags. There are tiny readers, such as the Tertium Blueberry iS UHF, that can be linked to a cell phone via a Bluetooth connection. This device can write to or read tags, and the data captured can be displayed on the smartphone. You could connect the Tertium iS reader, or a similar device, to any minicomputer equipped with Bluetooth capability.
