Is Captcha really required in your form?

Captcha is used in forms to make sure that the form is submitted by a user.

There are software tools that can 'read' your web page, parse your form and automatically submit the form just like a human user would. Usually, such 'form submission bots' post spam advertisements, expecting clicks from you.

Captcha prevents such submissions by displaying an image that can be read only by a human user. So the Captcha images are difficult to read. There are random lines and dots, characters are turned and skewed so that the 'automated bots' can not read it.

Captcha does not add any other security to your form or your website.

Adding Captcha to your form considerably increases the difficulty for your user to submit your form. A very good percent of your web page visitors will abandon the form itself fearing the Captcha.

Simfatic Forms has security features to prevent automated submissions without using Captcha.

Save your users from trouble; do not add captcha to your form.
