Let's start by cutting through the job title. A Radio Frequency Identification Device Specialist - typically called an RFID specialist or just an RFID tech - is not a scientist inventing the future, and it's not a desk job buried in code all day. It's a hands-on, systems-thinking role that sits somewhere between hardware technician and data analyst.

When it works, nobody notices. When it breaks, you're the name everyone calls.

To understand the job, you have to understand the basic tech - and the best way is to picture a typical supermarket checkout without a human scanning a bar code.
