How Can I Read RFID Using Wi-Fi?

Posted By RFID Journal, 11.23.2017

Is this a feasible setup?




There are many different types of RFID systems. One type of active RFID technology sends signals to Wi-Fi access points, so that tags can be located. These systems need to be set up and installed by professionals. I think what you are asking is how to read a passive RFID tag using a Wi-Fi router or access point. This is not possible. They operate on different frequencies, use different protocols and are not designed to work together.

David, I would add something more to what Mark has mentioned. If a fixed reader with WiFi connectivity is installed, a middleware can communicate with fixed readers on WiFi, read tag information and then send it to backend system. A handheld scanner also can read tags and then send them to backend using web services. Naresh

Thank you for the feedback. Which means to use/integrate Wi-Fi technology, only an active tag is allowed?

Can I ask two questions. 1) There are no possibility of using passive tags and wifi technology together (to locate and read passive tags)? 2) Is a RFID reader a must to read passive tags? Can they be read by other means than RFID readers?
