Description Author

This class can display and validate digits for the user to enter.

It can take code made of digits from 0 to 9 and renders a pad arranged randomly made of 16 buttons that the user needs to click on the right buttons to match the validate code digits.

The class can also check if the user has clicked on the right buttons with digits that match the code that was provided initially.

Depending on the configuration of the class, the code can be typed on the keyboard or necessarily with the mouse. It can optionally be used to avoid robots.

Some times it is necessary that applications verify if a user accessing the site is a real human, rather than a robot script that its trying to abuse from the system resources.

This class provides a solution that consists of a key pad that displays on a Web page. Then the users need to click or touch on keys that appear on the screen to demonstrate that they are real humans to enter the right codes by the right order.

This way this solution can work well on computers on which people can use the mouse to point and click in the buttons in the right order with the codes that appear on the page.

It also works well on devices with a touch screen like mobile phones, tablets or computers with a touch screen, as the users just need to touch the buttons to achieve the same effect as clicking on the buttons using the mouse.
