Oddbean new post about login | logout I have a bar in Charlotte that will accept Bitcoin as tips. I'd like to this with a static QR code - not using their POS system. What would be the best way to accomplish this? #asknostr
I'd prolly generate a BTC addy offline using your preferred method, taking care to stow away the corresponding private key in safe location. Feed the addy into your choice of QR code creator, display, then sweep the private key into electrum wallet or such when time comes.
Has to be lightning or ecash for tips. Can't be do onchain for these small tx.
I guess top pretending that sending 30 cents with 0 fee is showing your bartender appreciation then, or just drink Michelob light at home alone.
You gonna send $5 with a $1 fee on chain? Send them $5 over LN with basically zero fee.
I'd say a QR code to a lightning address.
Yes, thanks.
Hosting a node as base settlement; then running a web-server (either a vps or one self hosted too) which can run webpage's and lnbits' services pointed towards customer final screens (qr codes, although lnbits also has pos and some other useful stuff for businesses). The con is you ought to work lil extra to link devices and networks, the pro is that the web-server is what the client `sees' so you gain privacy by obfuscating your node as well as it's easier to give it maintenance without losing the front-end
I had an idea to create a tip jar using nostr native tools, but I think it might be too advanced for new coiners. https://habla.news/u/bloggingbitcoin@iris.to/the-nostr-tip-jar I suggest onboarding each bartender onto minibits.cash wallet. Each 12 word wallet is also a nostr key so you can pay them like venmo right away. It is cuatodial like WOS, but uses cashu + lightning.
Qr code to a BTC PayServer website. We have different payment solutions, but not all wallets support everything, so having a webpage that provides the optionality and can change as tech improves over time too is probably best.
Getalby.com i think you can make a qr of an lnurl. This is custodial but thats the only practical way for LN.
Okay, I just confirmed this: Create an account with getalby.com You'll get an ln address like babeswhobitcoin@getalby.com Now put that into any QR generator and print it out. I just tried this sending from MutinyWallet to my seperate account at Alby and it worked! https://image.nostr.build/ Here, I've even made the QR for you. 7b4b8a56f59e968d62c7f5a9034f0893b0591cb5144ef665dc59e42cebabfc64.png
Actually, you can do this same approach with any place that can create an LN address. I would actually recommend getting a mutiny plus address. @OpenSecret Get https://www.mutinywallet.com/
How did you make the QR code? Unsure how to do that with the ln address
One way, if you're on Debian/Ubuntu or similar, is from the terminal: qrencode --type png --size 256 --output <filename>.png "lightning:<user>@<domain.tld>" There are other output types such as "ansiutf8" that can output to the terminal.
LOL
Just type "qr code generator" into any search engine. Paste in your ln address. There's no risk of sharing or uploading an ln address.
I did that and it didn't generate 😬 I was using vipsats app
Huh, vipsats? No, use Google or duckduckgo, any search engine will give you links to websites where you can paste text and spit out a qr code image for free that you can save.
Ya, I did that with an address from vipsats https://vipsats.app/
It doesn't matter where you create an LN address. A QR code is just a machine readable format. You can put any text you like into a qr generator. Qr.io
ok yep! that one worked. the other generators I used did not work! thank you!!!
BTW, it super pisses me off that people can't answer this type of question clearly and directly. The thing you've asked for, a simple QR code to allow for easy bitcoin payments, is probably the #1 question of anyone that has learned about self-custody and is now ready to do some business with bitcoin. "How the fuck do I incorporate bitcoin into my business?!" Well I think custodial LN addresses are the simplest way. Self-custodial LN fucking sucks and is impractical for 99.9% of people. Eventually when the account starts to fill up you can send to on-chain address. You can do this directly from Mutiny Wallet. EASY. FUCKING. PEASY!!
