Today, there is a gathering of students, I went there, there are still a lot of people, we have arrived early, I looked at, there are a few I can call the name of it. We talked together. My deskmate is now doing software development. The feeling is very good, she said now passive RFID, very wide, I listen to her to tell me something about passive rfid. It’s really good. I like it too. Passive tag contains data stored electronically, you can read and decode the use of RFID reader and so on, the passive RFID, the application is also getting wider and wider. A few minutes later, all of us are here.
