Doesn’t bank account information have to be exchanged for an ACH transfer? Seems good between people you really trust (although definitely less convenient), but I’m not sure I’d be comfortable exchanging bank info with an acquaintance.

Thanks for the suggestion. At first glance it does seem “less bad” than most of the other options, assuming it works on custom ROMs. I think the problem will be finding others that also use it, since it doesn’t seem as popular as the other options.

I think you missed the part of my post where I said “it isn’t always a reasonable option to use cash or mail a check.”
