in reply to Golf: Replacing part of a string with "*"

More fuzzy (the result)

substr($string,rand length $string,1,"*") foreach 1..12;   # 5****23**
+*34**7*

Update: No guarantee included :-)

That's bad for readability (harder for the user to figure out which one of his cards was used), and it's bad security (since the number could be obtained over time or if multiple retailers did this). And of course, there's are times when two, one and even no digits are hidden.

I know one bank that use it... but I agree with you...

Actually a couple issues with this, 1) not guaranteed to use any asterisks (usually will), 2) since they are different each time with enough receipts you could get the whole number.
