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.
