And cash certainly wins availability by a long shot, it can't be blocked by any kind of outage. If you don’t have enough cash in your wallet then you don’t have any availability. If you have a internet outage your debit/credit cards still work offline. Also security does not equal privacy. If you are living in a state where this is true, you have bigger issues with the entire system than ATM skimmers. > Credit cards don't have a PIN, that's a debit card. Everywhere I have lived bar the US has PINs on all card types. It’s only a matter of time before it becomes ubiquitous in the US too.
