The new feature is integrated directly into Safari on iOS 8 where users will be prompted with a “Scan Credit Card” feature when presented with a credit card field on websites. Apple then uses character recognition technology to auto fill data fields from the snap shot. From the sounds of it, Apple will not require support from retail websites and others that require credit card number input. The feature, not unlike what Apple is currently doing with iTunes gift cards and Apple IDs, will also work for expiration date and CVV fields.
For some, this may not seem all that useful considering in many cases users simply enter their credit card data once and have Apple’s Passwords & AutoFill system take care of it from there. However, Apple is also introducing the camera scanning feature inside its AutoFill system to allow users to use the new tech to input data from there as well, according to the report.
