- parse encoded data to a JSON object
- If data is an URL, convert it's querystring to a JSON object
Best Practices
ZXing webservice can be use to generate a QRCode.
Generated QRCode should contains an URL with parameters.
- Anyone using the QRCode will be redirected to that URL (that could explain the webservice)
- Decoding the QRCode will still works
