Choose CAPTCHA type:

Our system Flox uses an anti-spam form reCAPTCHA powered by Google. Nowadays is possible to activate 1 type of CAPTCHA from 3 different options. 

1. reCAPTCHA v1- is an image with special code visible under the website forms. Before the user sends form has to re-write the security code. The humans can fill in CAPTCHA but the robot doesn´t. The code is usually covered with a special watermark which robots can not read. The form is sent just in a case the security code is re-write correctly.

reCAPTCHA with text code

attention bulbAttention: reCAPTCHA v1 supports only one verification code per page. In a case, you use more than one form the security code will be visible just for that one form let´s say registration form. Contact form on the same page will be not possible to use and send, the security code is missing there. 

2. reCAPTCHA v2- instead of the text field option, the system shows button "I´m not a robot". When a user clicks on the button Google verifies a user's identity.  

A. If the user is logged into Gmail account,  system just verifies his identity
B. If not, the system shows an image puzzle which has to be solved by a user.

3. Invisible reCAPTCHA- is a special way of form verification. There is no text, no button or image to re-write. A verification process is based on the button click for sending forms. If the user is verified and logged into his Gmail account, the system sends a form directly. If the user is not verified the image puzzle is shown. And needed to be solved for verification. To make sure it is not automated robot.

Please, in a case you are using a third option- Invisible reCAPTCHA place this info into your footer space or into terms and conditions. It is mandatory to inform your customers about this action.
