SAN FRANCISCO -- A technical problem affecting the Visa network barred people from using their credit and debit cards for about 45 minutes on Sunday, the cards company said.
The outage was caused by a recent update Visa has made to its system and the company had trouble processing some transactions as a result, but the system was operating normally by the end of the day.
Consumers and merchants reported having Visa cards rejected on Sunday. The outage appeared to occur between 2:40 pm and 3:20 pm EDT.
Sunday’s glitch was unrelated to the security breach potentially affecting Visa and MasterCard customers that was reported Friday by credit card processor Global Payments Inc.
