Most of the time you need to enter your credit card information when shopping online, and it is a hassle to enter long numbers on mobile devices. Therefore, the Safari in Apple iOS 8 introduces a new feature, which allows users to use device camera to scan credit card, and then automatically identify the number and enter the corresponding information, thus avoiding trouble of manual entry.
Before, apple also has provided other convenient input methods, for example, user can preset credit card information in the” password and automatic filling” program in Safari, then to have a quick choice in the subsequent online shopping. It is still effective now, but iOS 8 will provide an additional “scan credit card” option. Its principle is to use the camera to capture credit card, and then use OCR (optical character recognition) technology to input digitals to the corresponding Safari text boxes.
