Thanks for the reply - this wasn't a knock against you guys per se, just my sense of distrusting anything that wants to connect to banking details.

For example, transaction knowledge is often used as a verification system by banks, and in general the more knowledge a phisher/scammer has about you the more able they are to socially engineer their way into your life.

I'm perfectly prepared to believe that I'm being far too paranoid about this kind of thing, and that many (or even most) other people wouldn't be as concerned as I am
