It encountered the system error on Tuesday, a day before the Senate initiated an inquiry into recent issues in the banking sector.

On Wednesday, BDO Unibank confirmed at a Senate hearing that seven of its automated teller machines in three undisclosed locations were compromised by "skimming devices," which copies data from an ATM card for replication.

Reports of skimming of BDO accounts came Friday, just a week after an "internal error" paralyzed electronic services of Bank of the Philippine Islands (BPI).

The June 6 BPI "internal glitch," which saw incorrect postings of withdrawals and deposits, suspended transactions at automated teller machines, cash acceptance machines, and point of sale systems for two days.

At the Senate hearing, BPI assured the public that the error did not lead to any data breach.
