ResuPress's Coincheck Payment Gateway Integration Asp.net/PHP/Java site

Tokyo's Storys.jp(ResuPress), announced it has launched a bitcoin(Payment Gateway) exchange called Coincheck.

Users can buy, sell, or send bitcoins after depositing money into a bank account designated by the company. ResuPress charges a commission of 1% on bitcoins bought, withdrawn, or remitted through the platform. To prevent fraud or money laundering, users must submit identification to withdraw more than 10,000 yen ($100) per a day.

Coincheck offers three advantages:
Sign-up can be completed in as little as one hour
Available 24 hours a day
Easy-to-use interface

Can any one help me how to integrate it in our site? Asp.net/PHP/Java site?
