Alipay, a China-based online payments provider, has launched its travel card service, named Alipay Overseas Transportation Card, in Singapore, Thailand and Macau to step up its expansion in the overseas travel sector.

The service will allow Chinese travelers, who account for a collective spending of $128.6bn abroad, to purchase public transportation passes in the three Asian destinations in yuan through Alipay’s mobile application, Alipay Wallet.

The transit card service will enable travelers to collect the transport passes at designated booths at the airport by scanning a barcode on their mobile phone with the option of getting the unused credit refunded back on their Alipay accounts when they return the physical cards.

Alipay will roll out the service for Chinese visitors to South Korea in the near future.

Sabrina Peng, head of Alipay International, said: "With nearly 100 million outbound Chinese tourists, Alipay is excited to be working with our partners to offer this new transportation card service to travelers.

"The convenience of our users is of paramount importance to us, and we hope to be a useful travel partner to them as they explore the world."
