NatWest has temporarily suspended its Get Cash smartphone app that allows users to withdraw cash without a debit card, following customer complaints of stealing of money from accounts.
The bank has also confirmed that reports of fraud is behind its decision to withdraw the application, according to BBC.
The application allows users to select an amount between £10 and £100 and then a secure cash code will be offered by NatWest which will be valid for three hours to withdraw the selected amount.
However, users have registered complaints that the app has been used by frauds to take out money from their accounts without their consent.
NatWest said in a statement that the firm has been fully committed to the prevention of fraud and have stringent security procedures in place in this regard.
"The Get Cash app is only available through the mobile banking App, not as a standalone application," NatWest said.
"Enrolment for the app requires the customer to first register for online banking, then mobile banking and can then proceed to download the app for their mobile."
NatWest has currently halted the service for a ‘planned update’.
