Never ever have I seen a credit card number XXXed out. Are you sure about that? I am in Canada.. maybe this has changed and we are a little behind the times.
Good thing there is such a device as a passive RFID chip, where the VCC is powered via inductive coupling with the chip itself. The range can be "configured" to be quite small - thus you are safe.
The scary thing is the credit card receipt copy that the merchant keep that actually contain your number and expiry date!
