Apple Pay launches in the U.K.9
Currently, limitations with software prevent Apple Pay from being used on purchases over $31 USD. In September, merchants will update their POS software allowing the cap to be raised to $46 USD. These point of sale systems will be updating all day today as individual stores start connecting to the system.
Apple Pay can be used with the Apple iPhone 6, Apple iPhone 6 Plus and the Apple Watch. Using the card's security code, add the credit or debit card you use for iTunes into Passbook. After that is accomplished, other cards can be stored by snapping a picture of the card using your iPhone's rear-facing camera. Or, you can enter the information manually. To use Apple Pay with your iPhone, select the card you want to use, then hold the device near the reader with your finger on Touch ID.
While Apple Pay is just starting in the region, other banks such as Halifax, Lloyds, and the Bank of Scotland will be added this fall. And now that the service is available in the U.K., we expect it to roll out to Canada, China and other markets in the future.
