Usually is not how to like to understand and life does not have the knowledge of the relationship, which is good, I have encountered some embarrassing things. Just a few days ago, our downstairs area door is broken, we can always see the import door open, I think this is the case, our lives are really not safe ah, then find someone to repair the property, I said back to the people is to repair the doors are so difficult well, after the man told me that now the doors are RFID by using applications technology, the RFID applications technology to use is very safe, they are already and this aspect of the personnel contact, can be repaired very quickly, then heard the RFID applications, I really do not know what to say and because I had really never heard of RFID applications.
