If you don't provide access to nondeposit products, and your ATM is placed in service before 1/1/2025, you can comply by just sticking the FDIC official sign on the face of the ATM. You don't need to include the official digital sign on any screens. You will need to check the ATM periodically to make sure that stuck-on sign is still there and still legible. If it's been removed or vandalized so it's no longer clear and legible,. You will have to replace it promptly, so get a supply of the signs for backup.
If you put the machine in service before 1/1/2025, you can go the other route and use the official digital sign. It will have to appear conspicuously and continuously near the top of the "home" screen, near the bank's name. It also has to appear on each transaction page or screen relating to deposits.
If you put the ATM into service on or after 1/1/2025, you have to go the official digital sign route.
This is laid out pretty clearly in new section 328.4, which you can see
HERE.
