How to Model Digital Membership Cards in XML for Multi Platform Integration

[aaaditya]

Hello everyone, I am implementing membership card solution that uses QR codes. I will be creating a way for multiple mobile devices and web services to access member data by storing the information in XML format. My goals are to

1. Ensure the member's data is stored securely

2. Ensure the data can be accessed by mobile devices, web services, etc.

3. Have a way to easily generate a QR code from the data.

I'm investigating ways to design an XML schema in a way that captures digital membership card details as well as a membership ID and the level of access provided by that ID. I'd like to see how other developers build their respective XML documents that represent the same type of information.

Furthermore, I am looking at potential methods of using XSLT or FOP to generate either printed or digital QR codes that represent XML data. Any input you have regarding process examples, handling dynamic data, and generating secure QR codes would be greatly appreciated!
