PIN codes, security or insecurity?

A little while ago, I didn't have even one credit card. Now I have two, and a debit card. And the biggest problem is to remember all of the PIN codes. Really, there should be something done about PIN codes. They cause trouble when you have to remember more than one. Everything requires a PIN code or a password nowadays. It needs to be made more simple.

I like the idea of fingerprint scanners, but I guess they still have that security issue that was noticed some years ago. That the fingerprint can be spoofed easily by taking it from a coffee mug or something that the owner used. Hopefully if and when they get it secure, it will replace PIN codes.

Or you could use a iris scan, that should be pretty reliable. Or just insert a small chip under the skin, although it wouldn't be too hard to cut it out. Of course doing that without the owner noticing it, is pretty difficult. But cutting out a small chip from under the skin is still more of a security risk than someone cutting off your finger or eye(s).

But all in all, we need to find a better replacement for those damn codes. No matter if they are passwords or PIN codes, they have to go. In this world where people have all kinds of devices and services that require a code, it is impossible to remember them all. Yet, you still must have a secure access to the services and devices, so your neighbour can't buy a new car using your credit card and browse through your collection of kinky porn on your PC. It is not secure by any means of the word when you write down some of the codes. That is, and always will be, a security issue. We need a replacement, period.
