What is Captcha? A CAPTCHA is a type of challenge-response test used in computing to determine whether or not the user is human. You might have seen a blurred image or a question such as 2+2=? And you have to right the answer in a box while you are filling up a form on any website. This is used to check that you are a human and not a bot as there are many bots (software) which are used to overload the web page with queries etc.
There are many such websites which provide money in exchange of solving the captchas. You can earn somewhere b/w $ 1 to $ 2 depending upon your typing speed.
