We do not understand what is in fact can ask those people who know, so we can get a progress, not because they do not understand something because you feel shy, afraid of people joke not to ask, so what time do you have no progress, remember the time I met RFID solutions when I don’t know exactly what RFID solutions do, but I will find some information to understand the RFID knowledge of solutions, and then ask those who may know this thing, so to the end you will understand what is going on, so you can’t say anything just because give you to do one thing, then what you do not succeed, this is my experience.
