What is Address Verification Service (AVS) and does it work?

0

What is AVS?

AVS verifies if the billing address is the same as the billing address the cardholder’s credit card company (visa, mastercard, etc).  More specifically, the street number and the zip code is verified individually and the results are reported back.  Use AVS (address verification service) through your gateway such as authorize.net.  Firstly, require the customer to provide two addresses – the billing address their credit card company has on file and their shipping address.

Does AVS work?

Most thiefs are dumb.  They’ll acquire stolen credit card(s) and start using them with little regard to the billing address b/c they don’t care about the billing address; they only care about the shipping address of the order.  I’d say 85% of transactions the billing address the customer provides matches the billing address on the credit card completely.  Most mismatches occur with college aged students who are off to college or anybody that has moved recently and the billing address at their credit card company hasn’t changed yet.  AVS is not a foolproof.  There are a few ways the thief could have your billing address such as by acquiring data from another online purchase you made, looking you up in the phone book, or they’re somebody you know personally that is aware of your address once they’re obtained your credit card details.

What can I do?

As a merchant, you have the ability to automatically decline transactions that fail one or both of these tests during the authorization process.  This method is not fool proof by any means, but will help you deter some fraudulent transactions.

Is AVS worth it?

AVS will cost the merchant usually between 5-10 cents per authorization.  To me, I’d say yes, it’s worth it.  AVS a tool I check on a daily basis when scanning for fraudulent transactions.  Below is an excerpt from the email I receive from my online merchant outlining details of the transactions.  The AVS results are included.

Selenium IDE – How to follow links that open a new window

9

While building another test case, I ran into a situation that wasn’t working with the standard point and click navigation. Clicking on a dynamic link opened a new window where I needed to continue my test, but selenium didn’t follow the newly opened window. There are a few ways to do this, but what made this one difficult was that the link and new window was a dynamic url each time.
The fix was to store the link in a variable, then open the variable link with selenium using “open”. To store the variable I used “storeAttribute” and the target used xPath to grab the hyperlink’s href attribute from the url and save the variable as “ticketUrl” as in the image below:

How to get remote desktop to span multiple monitors

0

I run Windows XP with dual monitors and it’s really annoying to be able to use only one monitor when using remote desktop. It’s like trying to eat steak with a spoon!
Anyway, to have the remote computer’s desktop span multiple monitors, type “Mstsc /span” at a command prompt on your local computer prior to making the connection. The connection prompt will appear when this is run. The catch is that both monitors must be the same size, same resolution, and positioned side by side.
