Apple got Visa, MasterCard, and American Express to team up for its mobile payments system, but now Citibank and Wells Fargo are joining the mix.

Wells Fargo sent an email to customers on Friday, telling them that Apple Pay will be possible within the iPhone 6. Citibank has told its users that Apple Pay will only be available in mainstream US territories as well as Hawaii.

In addition to these top banks that’ve joined Apple’s payment system, Walgreen’s, Staples, Toys ‘R’ Us, Target, Starbucks, Disney, Whole Foods, Macy’s, McDonald’s, Petco, Uber, and Panera Bread, as well as Bank of America and Chase have teamed up with Apple also.

One thing we’ve learned about Apple’s new NFC tech is that NFC will only work for Apple devices and near field communication will only work when iPhone 6 users are making purchases in Apple Stores. Android devices have contained NFC chips for the last few years, but Apple is likely to bring mobile payments mainstream with its 800 million iTunes accounts.

Apple has said that Apple Pay will allow users to ditch the thick and bulky wallet experience where users must carry multiple credit cards and a debit card when they visit local retail stores to make payments. Apple Pay will also prevent customers from being trapped by the use of plastic cards if they leave their cards at home. The iPhone will become the only device they need to pay for food, groceries, clothes, and other commodities.

How long will it take Apple Pay to succeed?

The implementation of Touch ID in iOS 7 and now iOS 8 is important because it will also prevent smartphone theft and thieves from attacking iOS devices. Thieves will be forced to utilize the fingerprint scanner to gain access, which will prove to be a formidable deterrent to smartphone robberies as they have occurred in the past. Maven says that physical bank cards could prove obsolete within two or three years.

PayPal recently took a swing at Apple in an ad in which the company said that “we want our money safer than our selfies.” Apple’s iCloud data breach has some concerned and worried about how secure Apple Pay may or may not be in the coming days and months.

Apple Pay will also prove compatible with the company’s new Apple Watch that’ll allow payments from the user wrist. Apple announced its iPhone 6 and iPhone 6 Plus on September 9, with sales commencing on September 19 and the release of iOS 8 two days earlier on September 17. A recent report has said that Apple will keep a small percentage of all sales conducted via Apple Pay (0.15%).
