What is the Third Type Related to EAS Systems that can Identify Specific Products?

There is a third type of an EAS system that we did not previously mention. It’s called RFID (which stands for “radio frequency identification”). This is not technically an electronic article surveillance system, although it is sometimes used as one.  The primary purpose （and biggest benefit） of an RFID system is to identify a specific product that passes by the antennas. For example, while AM and RF systems only detect that an EAS tag or label just passed through, an RFID system can detect that the tag or label is attached to Levi’s jeans, dark blue, size 34.  In other words, an RFID tag or label carries some identifying information letting the system know what’s leaving the store. We will discuss RFID systems more in a future article.
