Messaging app company Line announced today that it’s buying WebPay Holdings with an eye toward boosting its abilities in mobile payments.

WebPay built a payment service aimed at developers.

“The company is highly praised both at home and abroad for its cutting-edge technology, as well as service which offers easy to integrate API, short review period (3 working days in the shortest), secure payment system that does not process, transfer and store card data at member stores,” Line said of WebPay in a statement about the news.

Ultimately, the deal should help Line grow its Line Pay mobile payments service, which launched in December.

The mobile payment world has been exciting lately, following the release of Apple Pay, a mobile payment system for iOS. Meanwhile, Google keeps expanding the reach of its Google Wallet service.

Tokyo-based WebPay started in 2013. Investors include CyberAgent Ventures, Architype, and GMO Payment Gateway, according to The Bridge.
