“As a result, we have blocked card swipes (of our customers) in Mexico for the next three months,” Sanjay Ghosh, DGM -Credit Cards, Andhra Bank told Business Line here on Thursday.

“We have received some complaints from customers about swiping of their cards in Mexico, even though they were in India. This must have happened due to fraudulent cloning of cards,” the official explained.

Andhra Bank promptly sent messages to its over 1.40 lakh card holders informing them that all transactions in Mexico have been blocked for three months.

“This is a precautionary measure as there were some stray cases earlier too. If somebody is visiting Mexico, they can approach us,” he added.
