In the beginning I was really in rfid applications is not clear, because I did not at all, so I think I want to get familiar with the rfid applications, or after I go to work to a new unit, not the program, will also bring a lot of trouble to my work, so I thought I might as well go to the bookstore to buy a book about the rfid applications, so I went to the bookstore still have books like this really, really a great help to me, I am very happy, not too much I will use rfid applications for a long time, I am very happy, because it is of great help to my work.
