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?

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.
