Is it possible to develop merchant credit card processing facility for a chain of grocery stores on stellar? In many ways, grocery store payments are high volume micropayments and I thought Stellar may have a solution? We would like to move away from our current payment solution and reduce our costs by developing a solution on an emerging blockchain protocol. How big of an undertaking is a project like this? Is it even possible? What would it cost to develop a proof of concept?
Any thoughts or comments are much appreciated. Please way in. Thanks
