Should we have FDIC signs on our ATMs? Deposits to non-insured institutions may be made at our ATMs. It says we "may" but I am not sure how we would identify insured deposits and non-deposits being made.
Sec. 328.2 Display and procurement of official sign.
(a) (1) Other locations—
(ii) Other facilities. An insured depository institution may display the official sign on or at Remote Service Facilities. If an insured depository institution displays the official sign at a Remote Service Facility, and if there are any noninsured institutions that share in the Remote Service Facility, any insured depository institution that displays the official sign must clearly show that the sign refers only to a designated insured depository institution(s). As used in this part, the term "Remote Service Facility" includes any automated teller machine, cash dispensing machine, point-of-sale terminal, or other remote electronic facility where deposits are received.

It is not a requirement. We do not have the signs on our ATM facilities.

I was reading a commentary on this matter as I had to research earlier in the week, the sign is optional at ATMs.
