Could be, build a gift card with a private key so it can sign the transaction.
I think this is a cool idea actually, I don't know if it technically could work.
Topic: Could multi-sig replace gift cards? (Read 571 times)
Here is the situation:
13 year old Jenny wants to go to the movies with her friends. She texts her mom asking to send her a few ubtc to go see a movie. Her mom instantly sends the money directly to Jenny's phone but with a Multi-sig so she can only spend it at the movie theater. Jenny groans and says her mom doesn't trust her. Goes to movie with friends.
Couldn't businesses have some kind of code or software that allows you to instantly multisig with that business so the bitcoin can only be spent there? Could this replace the giftcard industry we have today?
