Could you let me have some details of the new legislation or any web links that could send me to somewhere that could provide technical details?

No joy on Google or HMSO.

PCI Data Security Standard

The information you need is the Payment Card Industry (PCI) Data Security Standard.

This is a roll-up of all the programmes run by all card providers (e.g. in Europe, Visa's progamme was originally known as AIS (Account Information Security), in the USA as CISP - and by other names globally).

It applies to all card providers worldwide.

Visa has a good page which summarises all the requirements plus has a link to the standard. All other providers and most banks have similar pages, but like this one they may be somewhat buried!


The PCI standard is actually a very good document. Normally these kind of standards are very woolly, and years out of date written by committees with little or no technical knowledge. This one actually covers most of the risks pretty succintly, and is well worth reading!


Here is a Mastercard International link as well:


Hope this helps,

Kind regards,
