changing credit card security code hourly

[#1]

I've been watching the news on tv this morning, some news about a new credit card with a constantly changing security code, may be coming sooner or may be later, what i'm wondering is, what of those people who use there card like with amazon or here with plus net who pay there monthly broadband or fibre connection bill, with a security code changing every hour it won't be able to take a payment automatically, i know it will combat credit card fraud yes, but it will make online payments very inconvenient i can imagine, unless plus net makes some sort of a system so the user needs to be prompted to enter the security code each month, there will be a lot of people getting cut off.

PN has been promising a new payment system for years

i doubt this will make them work any faster

[#3]

Cash or cheque?    long time since those words have been heard.... but they are most secure methods of payment !!! ..

Cheques bounce, cashier cheques and cash can be forged all too easily. So not really secure.

At last an optimist.   Plusnet have been forecasting an update of their billing system for more than 5 years.

"Cash or cheque?  long time since those words have been heard..."

Both were promissory though, credit card is the real deal machine even though it's invisible.... at least until the bailiffs turn up! 

Rarely if ever carry cash these days, offer a cheque and they'll assume you've wandered off from an old people's home.

I'm surprised they haven't been fined, like a few other companies, considering the never ending stream of ex customers who still get billed and money taken from their accounts.

Banks have been trying to do away with cheques for some years, because of the need for manual handlng. The are not that secure, they often slip through with no signature. My own bank refused to accept one I had written, because they said they didn't have a copy of my signature on file - they did, but simply had not realised.

I don't suppose you have a link to this story? Just that I'd like to see how they propose it would work.

The technique has been around for ages. You carry a token (card) which has a "random" number generator with an accurate time clock built in.  A new number every 30 seconds or so.The central server, knowing your card id and the time can generate a number to match your unique  "random" number. Thus it verifies the correct card is being used. There's normally a second password known only to the card holder, so to access the system you need to have both.

@Mook - thanks muchly - refreshed my mind that I had read that (or a very similar article) in the past.

It's basically the same rolling codes system that is used in most car remotes but adapted for use in the financial services.

And we all know that the rolling codes system can be cracked don't we.
