Overview
- CVN (Sometimes referred to CVC, CVC2, CVV or CVV2).
- A 3 digit verification number that is found on the back of a MasterCard or VISA
credit card, or a 4 digit number for AMEX cards.
- The CVN is not stored on the magnetic strip of a credit card.
- The CVN cannot be determined from the credit card number.
How it works
- The customer enters their CVN at the same time as entering their credit card number.
- Your bank checks that the CVN entered matches the CVN on the card.
- If the numbers do not match, the transaction will fail.
Technical Details
- MasterCard supported.
- VISA supported.
- AMEX supported.
- Supported by most banks, both nationally and internationally.
- CVN is NOT stored by eWAY.
- Diners is not currently supported.
Benefits
- Minimise the risk of charge-backs, if the credit card has support for CVN and an
incorrect CVN is entered then the transaction will fail. This means there is no
need to request a refund as the transaction is unsuccessful. This SAVES YOU TIME
AND MONEY.
- Use this information to determine if you should send your goods or services.
- If the purchase failed and a CVN was provided then the credit card is possibly fraudulent
and should be handled with vigilance.
- If you have doubts, then ask your customer to fax the front and back of their credit
card to you.
- Not all banks currently check the CVN - an incorrect CVN may be entered and the
transaction may still be processed successfully. However if a CVN is entered and
the transaction does fail this means that the CVN entered may be incorrect and should
act as a warning for you when dealing with the customer.
An example of how to explain to your customer where to find the CVN:
1. Turn credit card over.
2. Find the printed credit card number.
3. See the last digits? That's your CVN!
NB. The CVN is found on the front of AMEX cards, and is 4 digits long.

If you want to enter credit card details on your website and NOT be transferred
to the eWAY payment page then this is the solution for you. There is a minimum amount
of information that we require to process your transaction. You POST an XML document
to eWAY using your own valid
SSL certificate.
We then POST the resulting transaction in XML back to your website.
eWAY works in the background! Your customer never leaves your website!
Which platforms are supported?
The eWAY XML Solution uses XML which is platform independent. ANY operating system
that supports XML can use this solution, e.g. Windows, Linux, Mac etc.
Note: For other operating systems please consult your web server manual or web administrator
for information on enabling and configuring XML.
How Does It Work?
The
sample code
provided builds an XML document from an HTML Form. For the purpose of the demo they
are text fields. They can easily be made into hidden fields or server-side variables
so the users cannot modify the values. The information stored in the fields is converted
into a valid XML document that then communicates with the eWAY XML payment gateway.
The transaction is processed and an XML document is returned. Using the returned
information you can then update a database, send an Email, send an SMS or whatever
you like.
The shared solution does NOT require any components to be installed on your web
server or any SSL certificates to be installed. We let you use the eWAY secure 128
bit encryption for FREE. This solution can be used on almost any hosting solution
in the world.
If your website has a
Shopping Cart
already or you don't wish to use one of the many shopping carts supported by eWAY,
then you need to link your Shopping Cart to eWAY. We also offer an XML payment solution
for linking to eWAY.
Which platforms are supported?
The eWAY Shared Page Solution uses HTML <FORMS> which is HTML specificnot
operating-system specific.
Any web page that can POST an HTML FORM can communicate with the eWAY Shared Payment
Solution, on any operating system, eg Windows, Linux, Mac etc.
How Does It Work?
Your website transfers the user from your domain to the secure eWAY domain, where
all credit card information is captured and encrypted. Your site is only required
to pass order information such as customer name and other purchase details to the
eWAY Shared Payment page. Once eWAY completes the transaction, your customer is
automatically transferred back to your website.
The eWAY Shared Payment solution has an Auto-Redirect feature - your customer can
be automatically redirected to your site once a transaction is complete. This allows
you to easily update payment information on your site. There is no need to wait
and hope for your customer to click the"continue" button, so to speak.
You can then use the information eWAY returns and update your database, send an
Email, send an SMS, or anything else you like!
