I think, if we understand the RFID applications with knowledge, if we do not understand, we can discuss the solution, so we went together to learn this knowledge, hear my friends say, I think he said yes, now the RFID applications is really is too broad, if we don’t understand it, it is too outdated, but I found all of our lives also met a lot of people on the RFID applications knowledge, so learn some knowledge of RFID applications we use is really a lot, so we now have started for the school, until we find the right school, we can learn this knowledge.
