Bit-Pay has now incorporated the standard bitcoin: URI into our desktop and mobile invoices, for one-click payments from the most popular wallet apps.
By clicking on the "Touch to Pay" link on the invoice, if you have a bitcoin client or app that has registered the bitcoin: protocol, it will automatically launch a Send Bitcoins command and pre-fill in the amount and the bitcoin address. All you have to do is press SEND in your wallet. No more copy and paste! No more fat-fingering the amount!
This feature has been tested and verified with the following wallets:
PC: MultiBit, Armory
Android: BitcoinSpinner, Bitcoin Wallet, Blockchain Wallet
Apple: Blockchain Wallet
EDIT: Try it with your wallet! Click the blue "Touch to Pay" button on this page.
