Replying to Avatar Reichard Könige

I thought you were using an on-chain satscard from Coinkite. The bolt lnurlw cards can be problematic. Granted same problem a visa would have only they have checks for things like double billing and fraud. You're also relying on someone else running an lnbits or lnurl service and hosted wallet.

I believe lnbits let's you throttle transactions to any preset timeout you like. To avoid, their words, ass milking 🤣🤣🤣

But that would just delay a bad actor.

NTAG4XX cards have a chip that prevents double billing and fraud with internal counter and extra parameters for every spend. True, we didn't use it Riga, but we can get this setup for future conferences... then the problem you mention will be solved.

I have also spoken with Vivek from Coinkite on getting SatsCards working with on BTCPay POS... can be done, just if enough time in the day can be found for coding...

Although the cards in Riga were issued as static LNURLw (gift cards). They were not locked down.

We ran workshops with nostr:npub1n2ph08n4pqz4d3jk6n2p35p2f4ldhc5g5tu7dhftfpueajf4rpxqfjhzmc to help people get their cards set up as bolt cards with replay protection and a lot achieved self sovereign bolt card activation ✨
