Barclays claims that less than 10 customers were affected, the problem occuring when two users logged in to the service at exactly the same time. According to the bank, no fraudulent transactions would have been possible. A spokeswoman for Barclays said:
“Barclays views this compromise of the security and integrity of the on-line service as unacceptable. The security of customer information is paramount. The new service will not be re-released until we are satisfied that the particular issue experienced has been rectified.”
