The coupon app will be released on July 2 (KST) as a beta version.

Here are the results of implementation.

Adding customer benefits

A seller can add benefits that a custom will get on purchase.

These benefits will be stored in the steem blocckhain so that a seller cannot deny his/her promise.

The benefits will be shown in the coupon details page.

Drafting and Editing coupon

I have implemented drafting and editing coupon registration.

Dashboard for purchased coupons

You can see the purchased coupons in the profile screen.

If you click on a coupon, then a coupon that can be used appears:

Supported Countries

I noticed that mobile coupons are not common in most of European countries.

A real mobile coupon looks like this:

Some mobile coupons are able to be used in different countries but most are not.
To my knowledge these countries have mobile coupons:

• Korea
• China
• Australia
• New Zealand
• United States

Regarding this issue, there are limited numbers of countries to select when registering a coupon:

If your country uses mobile coupons, please let me know.

In terms of internalization the will at first support Korean and English

What will be open in July 2nd?

• No sign-up required (What you need is a steem account)
• Free account creation (for new comers)
• Coupon Registration
• Coupon purchasing
• Commenting on a coupon post
• Coupon dashboard
• Fancy UIs including dark mode
• [Stretched goal] General posting for users (which will be 'Community' menu)

Even though this app looks simple, there are so many things to be implemented. So please bear with me, I am doing my best to make this happen! Thank you for your support.
