But they said the RFID solutions, I think I still do not know there is such a thing, so, I think it is or I will learn some of this stuff, anyway, I think the RFID solutions is really very useful, because I heard them say is a lot of things used in real life, and I watched the RFID solutions what they do, I think, that if I do it, I certainly did not do such things, so I should hurry to learn about this stuff, like this if you encounter such knowledge, I also know how to deal with, but I also love this knowledge.
