A number of Nationwide customers have had their debit card payments declined in shops and online. A technical glitch was detected at around 1pm today and has reportedly been causing problems across the country.
The building society confirmed it was experiencing issues in a tweet on social media. Replying to one customer on Twitter, it said: "We're sorry, a small number of debit cards are being incorrectly declined online and in shops at the moment - we're working to fix this as quickly as we can."
According to data breakdown by outage tracker DownDetector, almost half the complaints (43%) are to do with online banking, reports The Mirror. Some 32% of people said they have experienced trouble transferring funds, while 25% are complaining about mobile banking.

In a tweet to Nationwide earlier today, one customer said: "Is there problems with account balances? I made a purchase but the money in still in my account and hasn’t been taken."
Another said: "I am trying to make a withdrawal from my Sky betting account to my Nationwide account its not going through.
"It is being declined from your side has there been some issues blocking this just I used my card to make a deposit."
A third tweeted: "I need to go grocery shopping but can't as my card declining - every month there is something new."
Nationwide has advised customers who have used their cards today to be patient, as "it might take longer than usual for the pending transaction to appear". It isn't the first time the building society has been hit by technical issues, however.
Customers saw payments going into their accounts delayed on New Year's Eve - just days after a separate outage in the run-up to Christmas.
Are you entitled to money back for bank glitches?
If your bank services have gone down, you aren't automatically entitled to any compensation - it instead depends on how badly the outage has affected you.
For example, if it made you miss a bill or some sort of payment.
It also depends on how long the service disruption lasts for and how quickly the bank worked to resolve it.
Nationwide has a dedicated page on its website to help you make a complaint.
If you're considering making a complaint, you should gather evidence about how the service issues affected you and for how long.
If you're in desperate need of access to your money but your online services are down, you should be able to go to your local bank branch to withdraw your funds as normal.
If you don’t have a local bank branch nearby or you're unable to get there, try and call your bank or contact it on social media to ask what to do.
