Apple’s NFC based mobile payment service — Apple Pay — launched in the U.K. earlier today. However, the launch of the service was not as smooth as the company might have hoped for, with technical problems leading HSBC — one of the banks supporting Apple Pay — to delay support for the service by two weeks.

It was only 24 hours earlier that HSBC’s UK account on Twitter had accidentally confirmed that Apple would be launching the service in the United Kingdom on July 14th. On the positive side, Barclays — one of the largest banks in the country — today confirmed that it is working on supporting Apple Pay sometime soon in the future.

The launch of Apple Pay in the U.K. has been crippled with issues and setbacks. While the service did go live within the promised time frame from Apple, it will be crippled to £20 per transaction, with the limit increasing to only £30 in September. While retailers can increase this limit by upgrading their point of sale terminals, they are not particularly interested in doing so because of the added investment associated with it.
