NatWest is inviting customers to send a personalised video to remind friends and contacts about unpaid bills as part of a viral campaign to promote its mobile payments app.
The campaign, developed by advertising agency M&C Saatchi, runs on a special microsite which enables users to send a personalised video message to friends about an unpaid IOU.
Users can choose from a selection of seven eccentric characters to send the message, which will be personalised with their name and the outstanding amount.
NatWest has been heavily promoting its new mobile payments tool, released over Easter, that lets customers send money to anyone with a Visa card and UK phone number.
The bank was forced to issue an apology to customers last week after a technical glitch shut down its mobile banking app for the second time in as many months.
