Signature Pad

Using signature pad for payment process is a new cash payment method.

Basic Functionalities

Basic functionalities of display on signature pad are:

• Show the advertising slide images on signature pad one after another according to de slide delay predefined in Mcompany( in our example, for company FoodMart, the slide delay is defined as 2000, which means 2 seconds).
• When the customer signature is required, the display image on the signature pad will switch to the signing image, additional 3 buttons will be shown under the signing image: done, cancle and delete.(these labels could be translated with I18n)

= Functionalities after signing

The following image is the signing image in our example.

• Customer signs, and then select “done”, the signature of customer will be saved as a blob-mapping data, saving as thousands of points with x,y, pressure... the display of signature pad switch to the advertising slide images.
• Customer signs, and then select “cancle”, the signature process will be broken, switch to the advertising slide images.
• Customer signs, and then select “clear”, the signature will be deleted, and waiting for the next action of customer.
