NatWest bank customers have taken to X (formerly Twitter) to complain about problems scanning QR codes on the bank's app.

Website has indicated that the application is experiencing problems with a huge surge in reported outages since around 7am.

According to the service 59 percent of the reported problems are related to onlin logins and 41 percent are related to specifically online banking.

The difficulties appear to be linked to NatWest Bankline, which is the premium online banking platform tailored for businesses.

Significantly, the system allows businesses to initiate payments of varying sizes and types, including domestic and international transactions.

X user @_LucyHannahC posted: "What is going on with Bankline? The QR code isn't scanning from the card readers, there's no notice or information anywhere, please assist urgently!"

@lanceeofthelane tried to seek help from the NatWest twitter account. They posted: "myself and another account administrator can't scan qr codes with our card readers on our bankline account? Is there a Bankline issue?"

Another said: "@NatWest_Help Bankline is not reading QR codes. Have a completion today."

He added: "Been on hold for Bankline for 45 mins."

One user said: "I tried phoning them as online chats are very busy, there is automated message that they know there is a problem logging in that they are trying to resolve but that mobile bankline is working."

The issue appears to also be affecting businesses, with one user complaining that the "technical issue" is particularly bad for a business account as it is "month end".

The NatWest customer service website indicated the bank is aware of a problem and said it is working on a solution.

A message states: "Bankline users may experience issues with logging in. Our Bankline mobile app is still available.

"We apologise for any inconvenience this may cause and endeavour to restore service as quickly as possible."

A NatWest spokesperson said: "Some Business Banking and Corporate customers experienced difficulty when attempting to log in and make payments via our Bankline service this morning. This has been resolved and we apologise for any inconvenience caused. There were no issues with our Online Banking and Mobile Banking services for our personal banking customers."
