Learn English – Abbreviation for “last four digits”

abbreviations

I'm now developing a web site at which users can purchase something. Users can also register their credit cards on the site. For security reasons, we show only last 4 digits of their registered cards.

Here is a problem. Our web site should support extremely small displays, so we cannot say "last four digits". Is there any good abbreviation for it?

Best Answer

Most of the time when I see this is says:

"xxxx-xxxx-xxxx-1234"

That may not be better than "last four digits".

So how about:

"X-X-X-1234" ?

The practice of doing this to give people the information that they are using the correct card is commonplace at the moment in industry - so, depending on your demographic, people should understand what is being conveyed.
