The answer is no. It's a highly secure, closed-loop, private network. While Interac operates the infrastructure, Interac also has the operating regulations and governance through which the transactions transfer from each financial institution. What we are facilitating is the financial institution that wants to employ the question and answer or Q and A type service. At no time, though, could the transaction be intercepted in transit. It is securely held at one financial institution and then, once released, the payment across the Interac infrastructure is securely facilitated into the receiving institution.
