KeyCAPTCHA Unique Technologies:
* Instead of guessing symbols, our CAPTCHA offers visitors to complete an easy interactive task.
* If KeyCAPTCHA hasn't been solved correctly, page refreshing doesn't take place that allows the user not to fill in the form repeatedly. It occurs since there is an initial checkup of CAPTCHAs in the KeyCAPTCHA servers before sending a filled-in form to the protected web server.
* Our CAPTCHA also can be used even if your hosting provider blocks all outgoing connections.
