Description |
A simple regex to check for only Visa and MasterCard with no dashes or spaces. Visa starts with a 4 and is 13 or 16 digits long, MasterCard starts with a 51 through 55 and is 16 digits long. I noticed that some of the other formulas don't account for Visa being valid with only 13 digits. I used this for a PayPal processor (which doesn't allow dashes or spaces) and modified it from others on this site. Enjoy.
