It has been about four or five years since i stopped bringing my wallet, taking my wallet with me all the time. When i go out, it's just keys and mobal ton. And nowadays we turn to use intelligent locks. So no kes any more. Just one mobile fone and you're good everywhere. But what if you run out of battery? You charge it. The interesting thing well, is that some beggars, beggars in the street would have a cu arcode in front of them. Oh, wow. That's a new kind of begging, like high tech begging.
