In SEA, we pay to traditional QR a lot, and it is very fast, if do it right, less than 1-2 secs. So, 92 sec suggest to cause long queue to popular stores.

https://plebqr.com/ does it in decentralized way, while Koral (https://btcln.app/koral, done by an Indonesian - https://x.com/roaringstars) does it centralized way. This is very similar to how some Africans do it, some e.g. Tando (https://x.com/tando_me) and a few more.

Fun fact:

Fedi - one can add Koral as plugin (extension) into Fedi wallet, which you can then use Fedi wallet to pay Indonesian QR (named QRIS - Quick Response Code Indonesian Standard) directly. That's amazing isn't it?

I can imagine a day that there will be 3 groups of entities:

1) LSP

2) Wallet developer

3) plugin developer - which developers from different regions can build the bridge between Traditional QR and LN payment, such that these plugins can be adopted by different wallet developers easily (like how Fedi does it).

E.g. Kilat wallet (Lightning in Malay language) uses Breez backend (nodeless) as their LSP, while it itself is a LN wallet, it also let users to optionally add Koral as plugin.

Use case: One travel from Africa to Indonesia can use Kilat wallet to store their sats in non-custodial way and without changing from Africa currency to Indonesian Rupiah, they can spend using Kilat wallet right away by scanning traditinoal QR code (QRIS) and pay.
