I have a business account without a telephone number displayed. Anyhow, a business account is the way to go, and it's free. They just have to verify your bank account. PP takes a little % of each sale, but it's quite a handy service, anyhow. There are other services around for taking payments, though, so it's worth checking them out too. I use PayMate, which is nicer than PP, but I'm not sure how how widely available it is outside Australia.
