Apple Pay, the feature in the Passbook application, can now turn an iPhone into a wallet by preloading customer’s debit and credit cards.
I think this new technology will explore a brand new market for Apple with the extreme convenience and the large number of iPhone users. Image that you no longer need to take your cards with you everywhere and do not need to worry about losing them when you are going out with your friends, all you have to take with you is your iPhone. Simply swiping your iPhone can get the payment done, this would definitely provide customers with a better shopping experience.
However, the limited locations for Apple Pay that compatible will be the weakness of this high-technology way of payment. There are only 22,000 compatible sites in the world. Although more stores are getting started to upgrade their terminals, the number of available shops will not be large in a short time, which means it will be the limitation of this technology somehow.
I believe the weakness will not limit Apple Pay in a long time, and it will be one of the major ways of payment in the future.
