Experiencing the Cashless, Walk-through Flow

Both the cashless and walk-through purchase flows were simple and sophisticated, so they seemed like they would be useful references when I implement something myself.

Through the store inspection, I took screenshots of every step, but I’ll omit them from this article. If you want to know, please experience the store yourself.

Articles That Show What the Cashless Store is Like

For a list of articles showing what the store is like, it’s good to read from the latest article in Developers.IO CAFE Newsletter | Series | Developers.IO in order.

If you want to know about the store’s condition as of November 2020, I think reading the following three articles will give you a general sense of the atmosphere.

Technical Articles About the Cashless Store

For technical articles, it’s good to read the articles in Developers.IO CAFE | Featured Category.

As the first article to read, I recommend I talked about Developers.IO CAFE’s backend at ServerlessDays Fukuoka because you can understand the technical overview.

If you want to catch up on more detailed technical overview, it would be good to also read the following slides.
