Installing an ATM machine on one’s premises

Your answer on installing an ATM refers : "since it is possible for one to withdraw interest bearing loans through this medium, it will not be permissible to install an ATM on one’s premises as one will be aiding in the sin of riba (interest)."

Question: 1) Will it not fall in the category of having a dual purpose as it is possible to withdraw halaal savings also. The property owner cannot be responsible for someone that uses the ATM for a wrong purpose similar to the sale of grapes?

2) If the illat is "the possibility of withdrawing interest bearing loans" then till point credit card machines should also be impermissible as a person whose account is already in overdraft is in fact paying by using "interest bearing loans " irrespective of using the budget or straight option of payment.
