HAPPY GO is a lifestyle app that combines the fun of earning rewards with the convenience of a digital wallet. It lets you use your phone to make a variety of purchases at a variety of stores. Once you're registered, you can log in and make purchases using your HAPPY GO card, which will be linked to your phone number.

HAPPY GO also offers rewards for a number of activities, including walking and taking healthy habits, and it lets you earn points by uploading a photo of the receipt for your purchases.

HAPPY GO is a free application. There is no monthly fee. You can also use the service without registering for a HAPPY GO card, but you will have to pay for the purchases you make.
