CC checker

CC checker is a simple-to-use application whose sole purpose is to verify the validity of credit cards. The tool is safe to use, as it does not require additional secured information beyond your credit card number.

The installation procedure is quick and uneventful, and doesn't require special attention from the user. Once it finishes, you can check out a Readme file and the single window with a plain layout, representing CC checker's interface.

All you have to do is write your credit card number in the dedicated dialog, and verify it with the simple click of a button.

The tool displays the status right below this field ("valid" or "not valid"), along with the type of credit cards it supports. You can clear the field to restart the process. Unfortunately, there are no other options available through this app.

CC checker uses a low-to-moderate quantity of CPU and system memory, has a good response time, and didn't hang, crash or show error dialogs in our tests. In one case, it failed to list a credit card as invalid, though. We must also keep in mind that CC checker has not been updated for a very long time.
