Tap and go

The tap and go feature on the current crop of credit cards is more than concerning, this lack of security to increase convenience is just madness.

Credit cards previously had PIN security and signature security that the vendor was required to check, none of that now exists. If someone physically has control of your card, they are able to run up multiple bills on your account to the value of $100 each transaction unabated - the cardholder can be liable. You can't even opt out, there is no choices, the card has tap and go for convenience - security is not an issue anymore. Let's face it, the banks are not making a loss - they are back charging the consumer.
