Recently mobile banking has become very popular with apps such as Barclays Ping it or 02 Wallet, it makes paying people a dream, for example going out for a curry having a designated payer and the rest sending their payments via these sort of apps. Seems like mobile phones will be used in the future as some sort of scanning device as shown in the video in the link which is quite interesting.

I'm in favour of this, I fucking hate money, I try to carry as least coins as possible as they just end up cluttering my pockets and weighing me down. I just carry notes if I have to and only use coins for things I have no choice for. I much prefer card and find it so much more convenient. I wouldn't be surprised in the not so close future card becomes permanent, it's also a much safer option.

Opinions?

Card becomes permanent? The fuck does that mean, it's not like it's temporary now.
