In my mind, a "Teller Policy" would consist of a multitude of seperate policy statements that encompasses teller operations.
For example, in my (online) policy manual, I have seperate policy sections for Branch Security, Cash Handling, Processing Transactions, Regulatory Compliance, etc.
We have a seperate online manual for detailed operational procedures.
An example of one of my teller policies is "We only will cash a check for a non-customer if it is drawn on [our bank]. In addition, a touch signature/fingerprint is required on the item."
The related procedure documents how to process the transaction in our teller system and properly capture a clean touch signature.
Hope this helps.
