By transfer would still need check-like(cheque-like) details, however it would need the bank information to be displayed as well, and unless properly secured by your banking institution to prevent fraud there could be larger consequences in putting the details for a wire transfer online.
I mean transfer just as an example. Isn't there a way to put something else other than cheque or cc? Should I use cheque then? Is there some customizable text for that?
There is check(cheque), CC, Paypal, 2checkout. Cheque can allpy in very general terms as you have to manually credit them anyway, so in the point you apply that credit you can note the real method.
