OCBC's Mobile Banking app has a Pay Anyone feature, which allows users to transfer money to friends by identifying them by their Facebook account, mobile number or e-mail address.
While the sender needs to have an OCBC bank account, the recipient does not have to be an OCBC customer, or even use the app.
Since the app launched in May last year, the monthly transaction volume of the Pay Anyone feature has increased sevenfold, "signalling customers' receptivity towards such payment modes", said Mr Aditya Gupta, OCBC Bank's head of e-business Singapore.
The app also offers a suite of payment services, such as bill payments, topping up ez-link cards and overseas telegraphic transfers.
OCBC also introduced OneTouch in March this year for iPhones, which uses Apple's Touch ID fingerprint identification system to allow users to access their bank balances using just their fingerprint. Since this service was launched, one million log-ins have been made with it, according to OCBC.
DATE LAUNCHED: May 2014
USER BASE: The bank declined to reveal absolute numbers, but said that there were 52 per cent more registered users in June 2015 as compared to May 2014.
TRANSACTION LIMIT: $100 per day for the Pay Anyone feature, and $50,000 daily or $300,000 monthly via Internet Banking funds transfer.
Aside from its Mobile Banking app, the bank also has a separate Open Account app, which was launched in September last year.
This app allows both OCBC and non-OCBC customers to open an OCBC 360 account via the app.
