The whole technical implementation of a credit card is flawed. The banking industry desperately needs another solution, magnetic stripe and pin is toast, magnetic stripe, pin and chip is also toast (man in the middle attack) and to do an online payment you have to provide a card number, pin code and CCV. On an internet which is full of personal information, provided by users or hacked out of badly secured databases. And instead of replacing what is flawed, insurances pay for the losses which are then charged back to users of the cards, by increasing fees or whatever. Yet, several institutions and countries mark Bitcoin as dangerous, it's a strange world we live in.
