Hi. My name is Luis and I'm the co-founder of cloudwalk.io, a software payment company who created a platform to develop and create applications to pci pts pos terminals.
We already have a integration with the coinbase.com service, but it can be easily customisable to other sass exchange. Using these terminals you can sell and buy bitcoins in an easy and secure way.
Please ping me at
