Singapore-based banks have revealed plans to introduce a series of new measures to all ATM cards to prevent security fraud, online media outlet jakartaglobe.com reports.

OCBC Bank will add new options which allow customers to switch on or off ATM withdrawals overseas, as well as send out SMS alerts for local and international ATM transactions. OCBC has already installed anti-skimming features on all its ATMs since July 2007.

Citibank has also revealed plans to upgrade its Citi Alerts service to include transaction alerts for ATM withdrawals. Citi Alerts is a free service which allows customers to receive instant SMS or e-mail alerts when transactions or other activity happen on their credit cards or banking accounts, including cheque, Giro and online payment transactions. In addition, customers will be able to receive their account balances and details about the last four transactions on their banking and card accounts via SMS on demand.
