The harder problem is how to do transaction submission.
LoRa for submission has enough bandwidth, however:
- No user has a wallet that can interface nicely with LoRa.
- LoRa -> 802.11 is unacceptable because "customers shouldn't be forced to connect to a sketch wifi AP", and "the typical mobile phone will overload the LoRa network with bullshit unrelated to Tx processing".
A more promising approach would be one of the QR code based airgapped wallet solutions (https://monero.town/post/223593 https://github.com/BlockchainCommons/crypto-commons/blob/master/Docs/ur-1-overview.md). Workflow would be the customer produces a QR code that encodes the Tx signature, POS system submits it over LoRa. This isolates the payment network from the customer, a hard requirement in both directions.
