This app is part of the not-for-profit rCredits project, an alternative community credit system designed to be the framework for a Common Good Economy -- that is, a community-centered economic system that puts people and planet first. See [url removed, login to view] for details.
Identify a customer by scanning a QR code on their member ID card (using Zxing open source subroutines). Post that code to the server. Receive an XML response, including name, city, state, and photo. Display these along with a simple transaction input form (one drop-down list, two text fields, one pair of radio buttons, one submit button). Post to the server, display error message or success message. Repeat.

Payment terms are negotiable. Successful completion of this app is highly likely to lead to additional work opportunities for Common Good Finance.
