Google is your friend!
Note that the algorithm presented at these sites does not actually verify the credit card itself, it simply checks the card number against the card security code to see if they work together as they should. As far as validating the card against the official databases, that may be a bit more complex...

Hi Richard,
I'd like to create a very simple custom browser to process one quick credit card subscription that requires filling out only three fields: the credit card number, expiration date and 3-digit card code. Our access device (a kiosk) does not provide a mouse. It does have a small numeric keypad.
What are the options for doing this through Rev today.. I'd like to know the simplest way possible!
create 3 fields and set their "autotab" to true (check it in the inspector)...
This will cause the cursor to go to the next field when the user hits the RETURN
and/or ENTER key...
To make sure that only numbers are being entered in the fields put this into the
script of the credit card number and 3-digit fields:
on keydown t_key if t_key is a number then pass keydown end keydown
Add this to the script of the 3-digit field:
on closefield if the num of chars of me <> 3 then put empty into me select text of me end if end closefield
To make sure that the expiration date field contains a valid date, put this into the script of that
field, supposed you demand the xx/xx/xx format for your date:
on keydown t_key if t_key is a number OR t_key = "/" then pass keydown end keydown
on closefield if me is not a date then put empty into me select text of me end if end closefield
That will delete the wrong date and sets the cursor again in that field...
Sorry no idea how to validate a credit card number ;-)
Hope that helps...
Thanks. Richard Miller Imprinter Technologies
