Effective immediately new bot security measures have been added to the payment pages for StoreSecured merchants. After multiple credit card declines a captcha will be shown to the user for them to prove that they are a human and not a bot. As the declines continue the captcha will be shown each time and verification required to continue. If there are several more declines the user will be temporarily blocked from processing a new payment for a period of time.
The captcha was added due to bots who are trying out credit card numbers on a few of our merchants websites resulting in high numbers of declined charges. The captcha implementation is meant to keep the checkout process easy for real users but tough on bots.
If you are not familiar with what a captcha is you can read more about them at the link below:
