What technology do you support?

So far, only PHP and Java are supported on the backend.

In both versions the viewer needs a website in order to place the CaptchaAd, as well as Flash plug-in version 10 or higher. That’ll get you your CaptchaAd.

Users will also need to have JavaScript installed.

Should one of these two conditions not be met, reCAPTCHA kicks in, providing a minimum of security.

Security Variant vs. Advertising Variant

Basically we offer two versions of CaptchaAd.
The security variant is to be understood primarily as a replacement for CAPTCHAs, while the advertising variant is to be understood as an innovative, interactive form of advertising.
