Clever! So how do you add the phone number to the receipt?
It is in the item's description. For example, if I buy 1.2 BTC for the address 'fooBitcoinAddress' and my mobile phone number is +123456789, the item I'm buying is described as follows:
"Position in Hall of Fame.Address 'fooBitcoinAddress'. Units: 1.2. Phone: 00123456789"
You can place an order an check it for yourself
