@keychain is probably the most used Hive Wallet and I think it could step a bit more with this feature.
I will ping @stoodkev, @cedricguillas and @theghost1980
As far as I know it seems that Hive and HBD payments are starting to be a reality, even if it is for a few people and small community business, it might be the beginning of something bigger.
The win feature for Hive Keychain
This can be used to Hive and HBD payments or for example to tip users.
A payment or tip in Hive will always be a transfer.
My idea is, instead of using Hive Keychain in traditional way to transfer Hive or HBD, fill the amount and receiver account, it could be generated a QRCode.
Features inside QRCode
For tips
It could be generated a dowlodable QRCode that the account could use in post.
If someone wants to tip, it could just open Hive Keychain, scan the QRCode, fill amount and memo (if necessary) and that's it, tip send!
For payments
This requires some more info, let's see a real example.
A coffeeshop account sell 2 coffee for 3 HBD.
Let's generate the payment method easely
The coffeeshop account open Hive Keychain APP on mobile phone and create a QRCode where it is filled, amount and memo (where memo could be the list of items consumed, in the example, 2 coffees).
The QRCode generated include on bottom, outside of read area, the receiver account, amount and memo.
After QRCode generated it will be showed in the App, all the consumer have to do is also open Hive Keychain in his mobile phone and scan the QRCode in coffeeshop mobile phone.
