You must provide the buyer with the number that identifies your bank (I can't remember what they call that but it's not the same as the routing number on your checks) and your account number. Anybody can get the bank number, and your account number is on every check you write as well as being transmitted to every payee when you make an electronic payment.
Since neither one of these is a secret I see no danger. If you are really worried open a new checking account with the minimum and use that for the transfer.
