We've made GUI POS & Wallet application work with the RTA testnet, so people can start testing and playing with the functionality based on the Point-of-sale use case.

At this point it's limited to Android ARM64 (there's also a POS version for Ubuntu x64). You can download the clients here:

(the CLI version is available on the Github as well)

Please open up a github issue if you run into any problems with transactions.  Please describe the setup and steps you took.

P.S. Current state of the project is to get the end-to-end functionality working using RTA on the testnet, flush it out, then based on the data, feedback, and interest proceed with fortifying the solution and addressing any real and potential vulnerabilities before moving to the mainnet.
