CDM is the abbreviation for Cash Deposit Machine. It means a cash deposit machine.
A Cash Deposit Machine refers to ATMs that allow you to deposit money directly into your account using a card.
You can use CDM ATMs to carry out transactions on your account without visiting a branch.
Today, most ATMs have a function called "Recycle," which combines deposit and withdrawal capabilities. Deposited cash can be reused by the ATM and dispensed back to other customers. For this reason, ATMs with only a deposit function are not very common in our country.
How does the deposit process work?
After inserting their card and entering their PIN, the customer places the banknotes into the machine's slot. The machine counts the banknotes, separates any counterfeit or unreadable notes, and has the customer confirm the total amount. Once confirmed, the amount is credited to the account.
The critical point here is that the amount credited to the account must match the machine's actual count. For this reason, banks regularly count the contents of the cassettes and compare them with the machine's records. If a discrepancy arises, it is investigated on a transaction basis.
In methods such as cardless deposits, identity verification may be performed through different channels, but the accounting logic remains the same: first the count, then customer confirmation, then the account entry.
