user3029: Which wallets support merchant message transactions such as bip 70 - 72? I want to build static html page where a user can just send their btc to my address with a message attached to it. The message would just be their email address so I can send them an order confirmation.
From my understanding the URI: "bitcoin:1zsfkje2034908234" would just have the r parameter and you would just specify a url for the wallet to goto. This url would just be something like this I'd assume: http://www.example.com?phone=83282829323
Let me know if this is even possible or if this is even correct?

user42587: I've been searching for the same and found this article. Below I put the wallets that support Bitcoin URIs (BIP 21) and Payment Protocol (BIPs 70, 71, 72,73). For more info please check the link.
+-------------------------------+--------------+------------------+
|            Wallet             | Bitcoin URIs | Payment Protocol |
+-------------------------------+--------------+------------------+
| Bitcoin Core (Satoshi client) | V            | V                |
| BitPay Wallet                 | V            | V                |
| Breadwallet                   | V            | V                |
| Mycelium                      | V            | V                |
+-------------------------------+--------------+------------------+

And add Copay to the table, which also supports BIPs 70-73 and is not in the link. For your URI question check this answer.
That's all I can do for you. Hope it helps!
