"AVS and CVV2/CVC2 fraud protection"
Posted by dan on Oct-29-02 at 01:26 PM (EST)
Since MULTICARDS started with collecting the
CVV2/CVC2 numbers - Fraud is not present anymore -why can this 3 digit number not be collected in the UShop ? Or can it ?
Almost all card processing systems include this possibility ..

There are various ways that this information can be collected.

The creditcard_template.html file currently allows for 5 credit card fields:
1. cc_type
2. cc_name_on_card
3. cc_number
4. cc_expiration
5. cc_issue

If you are not already utilizing the "cc_issue" number field - then the easiest thing to do would be to just add that "cc_issue" field to your template and give it any label you want.

I am already using the cc_issue field for Switch Cards - Streamline have just started to ask for the verification number on ALL Customer Not Present transactions (including Switch).

How can I add an additional input field?

TIA,

Tom Chapman

The easiest thing to do would be to just choose a label for the "Issue" field so that it requests both the issue number and the CCV number, such as: "Issue Number and CCV Number:". This will store both values in the issue field... but all you are really looking for is a way to collect that information anyway.

Or as a slightly more involved (yet more elegant) option, below are instructions on how to add an extra field to the Credit Card form:

STEP 1: Make a backup of your ushop-lib.pl script... just in case.

STEP 2: Open the ushop-lib.pl file with any text editor such as WordPad.

STEP 3: Do a search on the following line:

$cc_issue = &validate_string($cc_issue);

STEP 4: Immediately AFTER that line, add these three lines:

$cc_code = $form_text{'cc_code'};
$cc_code = &validate_string($cc_code);
$cc_issue .= " / " . $cc_code;

STEP 5: Save the script... as TEXT if your editor asks.. and try it out!

This will allow you to add a new text field to your creditcard_template.html called "cc_code" and will append that value onto the issue number.

Note: Before making this modification, you may want to check the laws in regard to collecting the CCV numbers. I think I read somewhere that CCV numbers cannot be stored in any electronic form. (ie. you have to call and verify the number unless you are using a payment processing system that validates the CCV number in real-time and does not store it.)

4 . "Not writing to .order file"
Posted by Tom Chapman on Jan-07-03 at 09:03 PM (EST)
Bill,
Many thanks for the quick reply.

I made the following changes to the script:

# From Credit Card Template.
$cc_type = "";
$cc_name_on_card = "";
$cc_number = "";
$cc_expiration = "";
$cc_issue = "";
$cc_code = $form_text{'cc_code'};
$cc_code = &validate_string($cc_code);
$cc_issue .= " / " . $cc_code;

I didn't have the complete cc_issue entry in my original script so I just added the new lines underneath.

The new form field (cc_code) is not writing to the order file - I have checked this both through the order reader and by looking at the text of the .order file as well.

Any suggestions? I have double checked the form to make sure the form field names are correct.

Thanks,

Tom

It doesn't look like you added the lines to the correct place in the script. Look for the line:

$cc_issue = &validate_string($cc_issue);

... within the "validate_credit_card_parameters" subroutine... and add the additional three lines there.

NOTE: You may have to do the search on just "&validate_string($cc_issue);" to locate that line because there are some additional spaces after the "=" sign... but they are not showing up in this forum.

7 . "cc_issue field"
Posted by Norma Scott on Jul-25-03 at 06:45 PM (EST)
I need to implement the CVV2/CVC2 support. I do not seem to have the cc_issue field in my credit card template file. It mentions it in the header, but when I look in the body of the file, it's not there. Am I supposed to add it and how so? Thanks.

8 . "getting there"
Posted by Norma Scott on Jul-25-03 at 06:59 PM (EST)
I think I at least partially answered my own question. I copied the "name" lines and just changed the text and used the cc_issue designation. Will this automatically write correctly to the order so I will be able to retrieve it using the Order Reader? Or do I still need to do something else? Thanks.

9 . "more questions"
Posted by Norma Scott on Jul-25-03 at 07:18 PM (EST)
Ok, I have a related question for you. I need to be able to collect that CCV code (we recently switched from a PC based process to a card swipe process to speed things in our brick/mortar store, and in order to do internet orders, that security code is required), but I don't want it to print out on the Order Reader form because we print that as a packing slip for the customer's order. I wouldn't want that slip to fall into the wrong hands, who would be able to use the credit card info "legally" because they have the CCV number. Any ideas for a solution?
