Will they ever run out of credit card numbers?

Just been having a think and I was wondering, with all the chip and pin technology out now, I was wondering if credit card companies could ever run out of credit card numbers?

Millions of them must be in circulation and I can't seen two card numbers ever being the same with different start dates, so how would they tackle this problem if it ever come about?

maybe add another number? but surely this would have to be implemented onto existing systems and cost the earth.

Another thought also is why can't home users (like us all) have some kind of credit/debit card reader that saves the hassle of typing the details every time we buy something on line and running the risk of having key loggers or other nasties out there.

Shops have em, so why can't we? Surely it would take the time out of ordering online.

Not in the foreseeable future. I'm not good at maths but I believe there are something like 1000 trillion combinations of numbers with the 16 digits in a credit card number (10 to the power of 16).

As for the second part of your question I have seen some businesses proposing to do just that. Home users would have a scanner for their credit card. I'm not sure if you would enter a merchant code or something so it would know where to send the money.

I suppose if you had a reader plugged into your phone line or something then it could read the cards and send the info to their end in white noise, like the old modems, and then de-code the info from that. It'd save trying to give numbers over the phone. Something which sent numbers/text over the phone would save a lot of hassle saying "there' no H!!" or "15, not 50".

I think they should make something USB wise which uses encrypted software that protects any card details and interacts with verisign or something, still have the option for manual entering, but have a button on the payment but that says "to pay via electronic reader press here".

One thing it would banish is incorrect entering of numbers or not knowing if to type in your issue number or not on visa debit cards.

They could even build the card reader with some kind of keypad on (like mobile scanners they used in resturants) that you can type your chip and pin number into.

yea I heard about the thing with shell, I'm always careful with garages tbh, I tend to pay for fuel with cash everytime, even more so, if I'm in a town center I tend to see what I want first then goto the cash machine for the cash, that way i know exactly what is going out of my account, another thing I might start to do is change my pin number every couple of months, just to make it extra hard. lol
