Integrating QR Codes or URIs

Zent Cash Mobile supports two kinds of QR codes.

• Standard addresses / integrated addresses - This is simply the address encoded as a QR code.

• zentcash:// URI encoded as a QR code.

Your uri must being with zentcash:// followed by the address to send to, for example, zentcash://Ze4qSTYgPABXiyh3Qak2gLRUXXCZzNaCC7qDDCdBqpLVjVduz6e6SFC16Eh9bd1cju9JDPhBDFRGz8HaAym5qvYV2fvQkkxtW

There are a few optional parameters.

• name - This is used to add you to the users address book, and identify you on the 'Confirm' screen. A name can contain spaces, and should be URI encoded.
• amount - This is the amount to send you. This should be specified in atomic units.
• paymentid - If not using integrated address, you can specify a payment ID. Specifying an integrated address and a payment ID is illegal.

An example of a URI containing all of the above parameters:

zentcash://Ze4qSTYgPABXiyh3Qak2gLRUXXCZzNaCC7qDDCdBqpLVjVduz6e6SFC16Eh9bd1cju9JDPhBDFRGz8HaAym5qvYV2fvQkkxtW?amount=10000&name=Starbucks%20Coffee&paymentid=e1b0bb215fb4b7af6f41f0a325b59252f2836ec831c528d75703ffbf8966fe0d

This would send 100 ZTC (10000 in atomic units) to the address Ze4qSTYgPABXiyh3Qak2gLRUXXCZzNaCC7qDDCdBqpLVjVduz6e6SFC16Eh9bd1cju9JDPhBDFRGz8HaAym5qvYV2fvQkkxtW, using the name Spanish Coffee (Note the URI encoding), and using a payment ID of e1b0bb215fb4b7af6f41f0a325b59252f2836ec831c528d75703ffbf8966fe0d

You can also just display the URI as a hyperlink. If a user clicks the link, it will open the app, and jump to the confirm screen, just as a QR code would function. (Provided all the fields are given)
