Yep, good point.
Another interesting use case would be using the card as part of a crypto escrow.
The problems being solved here are:
- walking around with a device that can access a large wallet that could be accessed under duress or coercion
- Key Pairs are hard to remember and type
___
- pre-pay an escrow online with $100
- have a payment card in your pocket
- meet person with another card
- set a payment amount
- touch cards
- escrow unlocks the amount as soon as either card pushes the update online - which if online could be immediately
- card confirms the transaction??
- can also delay the transaction, and if both cards are lost in the meantime, the transaction doesn't go through
- can also specify the payment amount as "set later"
- receiver can also request an amount
- escrow can be funded after the meeting
- good for 1:many payments too, eg splitting a bill
____
cards could also be Key Pair generators, for transferring public keys to other cards, with the exchange recorded for later use. No escrow required. A lot of benefits over handing out printed QR codes of addresses.
- altmanaltman 17d agoOkay so everytime I need escrow I will have to do all this? And use a different account anyway? Does not seem more convenient than current systems. Seems like you're trying to make the problem meet the solution instead of making the solution meet a problem and not considering actual user experience.
- adrianwaj 17d agoI don't know a lot about this area, but I like the [1 doge = 1 doge] thing where people completely stop thinking about dollars and crypto-to-fiat conversion. The card can work with Lay-buy/lay-by: _____ You go into a store, pick something out. Get a crypto address for it and the amount required with your special card. They set the thing aside. You leave and return to the store when the transaction has gone through and get your stuff. You don't pay immediately because you don't want to be walking around with a crypto wallet or a crypto debit card. The merchant doesn't want to pay fees either when dealing with an intermediary. There's no fiat conversion either, at least not as a given. _____ Gemini says this: "If you want to do this today, ask the merchant to print or email you a dynamic checkout invoice/QR code so you can complete the transfer on your own device later." But how widespread is that? "It is virtually non-existent at retail scale. While the underlying technology exists, you will practically never encounter this specific workflow in the wild." https://share.gemini.google/ZBHVZo47ZSn1 https://share.gemini.google/ZBHVZo47ZSn1 The "special card" is an evolution of that use-case and organizes it better. You can leave home without thinking about dollars, ready to pay with crypto and not worry about being robbed. No worrying about stockpiling a bunch of receipts either. It's just a 2-step buying process, that's the downside. The shop also has to hope you end up paying once they set it aside. Maybe they'll need a deposit. They can offer deliveries? Another idea is to pay online and collect it later. Use the card to authenticate yourself when you collect. That would need some decent tech backing it. Make it non-committal where if you don't collect within a certain time frame, you get your money back but lose a penalty chunk. Isn't this what smart contracts are designed for - crypto transactions tied to real world events? The "special card" provides those events. [ conversation continued via link above ]
