User experience is what poses the biggest challenge to QR (Quick Response) code payments today, according to attendees at the recent Money 20/20 Asia conference in Singapore.

And the experts agree.

“It always comes down to user experience,” said Milind Sanghavi, head of digital payments at OCBC Bank, at a panel session alongside Jenny Zhao, co-founder of Singapore-headquartered aggregation payment platform UnPAY; and Chen Yu, president of Beijing-based payment service provider YeePay.

Responding to a live poll at the panel session, one in two attendees ranked user experience (50%) as the most significant challenge for QR code payments to go mainstream, followed by existing payment infrastructure (31%), security (9%), QR-enabled features (5%) and business models (4%).

“The challenges in the short term are going to be security and probably regulation,” said Yu.

“But in the long term, it is going to be user experience.”
