 The scheme component ("algorand:") is case-insensitive, and implementations must accept any combination of uppercase and lowercase letters. The rest of the URI is case-sensitive, including the query parameter keys.
 
+Note 1: the first `app=` in the presence of the method interprets as the destination app ID and the next ones in sequence would be considered app array members.

+Note 2: the `asset=` in the presence of the method interprets as an asset array member.

 !!! Caveat
     When it comes to generation of an address' QR,  many exchanges and wallets encodes the address w/o the scheme component (“algorand:”). This is not a URI so it is OK.

+If the URI is constructed for templating only so that other dApps, wallets or protocols could user it for any user then the account address in URI must be ZeroAddress ("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY5HFKQ").
