entry points security

My friend some time ago moved to a new home, I wanted to look inside their home, we can’t met for a long time, although before going to listen to my friend said the family atmosphere is very small, and the use of long advanced technology products, but still was shocked by the installation they entry points security in the cell door, I have to say this community friends choose security is terrific, the installation of entry points security that don’t have to worry about what is bad when they enter, and access is especially convenient, not like before that everyone had to do a card, is now fully into the fingerprint, hey, if my friend is not down to open the door for me but I really can’t go into.
