In working through the best practices for ODP, I'm a little unsure of the intended notification to customers procedure.
The guidance indicates that you must notify customers prior to a transaction being completed that will trigger their ODP so that the customer has the option to cancel the transaction. This must be done where "feasible"; I'm comfortable that at our ATM's (as mentioned in the guidance) is not feasible, and a notice will be posted at the ATM's. However at the teller lines and drive thru, must we give a specific notice to each customer at each transaction that is being requested which will prompt their account to go into overdraft?

We addressed that issue by saying that it was not possible and that the customer has to acknowledge some responsiblity to know what his/her balance is before they withdraw funds. There could be deposits for the account that the teller is not aware of.
Time will tell if we are right or wrong.
