If you accept cash deposits at ATMs, will you be including all of that in your CTR reports too?
For suspicious activity monitoring purposes, I review all customer ATM transactions periodically, and look for unusual patterns (dumping it into a spreadsheet then sorting by name). Most customers have only handful of transactions; some may have 10 or 15 in a month. I usually stop and take a looksie if it is over about 12 in a month, but have never had that generate a SAR. In theory I'm looking for a person who has three times as many ATM withdrawals as any other customer (60 ATM withdrawals in a month, with the maximum allowable amount on most of them). We don't accept cash deposits at the ATM so that simplifies mine a bit.
