That's a really good point you are bringing out here. There are many analogous sytems out there but most of them use special hardware for it and whats even worse is that almost all store chains try to build their own Self-service platform basically from scrach or on outdated tech and methods.

There are countless of stores using those scanners you mentioned, but why should we use extra hardware, if we have our phones?

In China, there are cashierless kiosks, where you can use your phone to pay for the products but traditional stores cant really implement this system.

In the US, Sam’s Club, is currently using their own custom build system thats gaining popularity, a system that basically works the same way as ours, but its not in any way standardized and really difficult for other stores to connect themselves with this system even if it were made available to others.

The main issues come down to the developing and integration costs as well as implementation time. Smarts has built something that is really easy to integrate and quick to set up, so even a small store can use it because of its cost-effectiveness.

Furthermore, we give the stores another method of payment to accept - cryptocurrencies. All the risks of crypto are covered by us - we will take the crypto form the customer and the store will get their money in fiat from us.

So in a nutshell:

• Very quick implementation
• standardized system that any vendor can use in a matter of hours
• cost-effective
• supports crypto

We've actually heard alot that "i've heard this thing in use somewhere", but never have they actually used it themselves.
