Ask HN: Is there an easy way to transfer money to people?
Or suppose I'm at a bake sale and I don't have any cash on me. I can just enter the name of the person running the sale and quickly transfer $2.50, with a note for my records saying that it was for a bake sale treat.
The reason I ask is: I haven't found such an app, and if there is one, it's not well-publicized. It seems like an interesting idea for a side-project. Thoughts?
