Depository transfer checks, commonly referred to as DTCs, are bank transfers used in a cash management system. These checks resemble a deposit check, but they do not have signatures on them. They are used by companies to expedite the movement of funds.

DTCs are a form of payment order whereby the issuing bank holds the funds until they are cleared and the check passes through the automated clearing house (ACH) system. The ACH system connects the accounts of payers and beneficiaries, allowing for funds to be transferred electronically more quickly and cost-effectively than using physical checks.

The advantage of using DTCs is that it can reduce the time taken for funds to be cleared. It does this by allowing banks to avoid the time and costs associated with manually sorting, distributing and reconciling checks. DTCs can also provide more accurate and timely reporting, which is beneficial for fraud prevention, cash forecasting and liquidation.

However, it is important to note that DTCs are not the same as overnight deposits. Overnight deposits occur when funds are transferred between banks on the same day, while a DTC typically takes several days. As such, they may not be suitable for all types of payments, as the transferring of funds may not be quick enough.

In conclusion, depository transfer checks are an efficient and cost-effective way of managing cash in the banking system. While they are not suitable for all payments, they can offer improved accuracy, reporting and fraud prevention, plus reduce the time taken for funds to be cleared. Despite advances in the electronic banking system, companies are still reliant on DTCs for some types of large transfers.
