Citibank debit card customers can now use Quick Lock feature to temporarily lock and unlock their debit cards through online or mobile app to prevent unauthorised transactions.
The functionality was first made available to credit card members last year and it has been extended to debit card customers.
More than 1.6 million locks and unlocks are completed by credit card members since last year.
Since the extension of lock/unlock feature to debit cards last month, debit card customers have used it at an average rate of 900 requests per day.
Citi Quick Lock to debit cards complements a suite of new mobile app features such as ATM/debit card PIN reset and activation of new or replacement cards, Mobile Check Deposit with increased limits and user experience enhancements.
Other features include personalised contact information for Citigold Relationship Managers and Citi Personal Wealth Management Advisors to request an appointment from the mobile app.
Citibank Digital, Client Experience, Marketing & Analytics head Elyse Lesley said: “Citi is constantly looking for ways to make banking more convenient by connecting with our customers when and how they want to be served, especially with respect to security and protection.
“Since our customers are increasingly active on mobile or online, we’re giving them another tool to directly control their account activity across the bank.”
Citi has reported that the number of active digital customers in the North American Consumer Bank rose 13% year over year in the third quarter, while the number of active mobile users increased by 22% during the same period.
