iOS 8.1 Public Release Coming on 20 October: What's New and Everything You Need to Know
Make contactless payments across hundreds of retailers and banks via Apple Pay in iOS 8.1

Another major Apple product launch, another problem blowing up on the twittersphere.

Apple Pay, the company's long-awaited NFC mobile payments platform, went live on October 20 and in the days since some users of the service claim to have been charged twice for every purchase.

The glitch has only affected people who have registered Bank of America cards to their Apple Pay accounts, with the bank promising to refund double charges.

Spokesperson Tara Burke said: "We apologize for this inconvenience and are correcting this issue immediately. All duplicates will be refunded."

Bank of America, however, has pinned the blame on Apple, a company still reeling from widely-reported scandals on its latest line of iPhones and recent operating systems iOS 8 and 8.0.1.

An Apple statement read: "We're aware of a Bank of America issue impacting a very small number of Apple Pay users.

"They're working on a fix that will be available shortly and reversing any duplicate transactions."

The problem was first reported by CNN tech reporter Samuel Burke, who discovered he himself was being double charged for Apple pay purchases.

A cursory glance at Twitter revealed he wasn't the only one.

Rohan Thompson said: "Problems with #ApplePay - it looks like my @bankofamerica account was double charged by @Walgreens"

A Twitter account under the name 'victor' said: "Just use apple pay with Bank of America got charge twice 75 cent product got charge 1.75 #ApplePay" (sic)

Apple Pay, released as part of iOS 8.1 earlier this week, allows iPhone 6 and 6 Plus users in the US to pay for products in or out of store using just their device, where they'll have stored credit or debit card details.

The new feature has major retail and banking partners, prompting many to believe it represents the breakthrough of mobile payment technology.

Just how Apple will fix the problem is not yet known; it could be a new software update to the iOS 8.1 or a hotfix.
