Types of ATM Machines: Functions and Key Differences

Article Summary

ATMs remain an important part of banking services. Although digital banking services continue to grow, ATMs remain a preferred option for customers to perform various transactions.

As technology continues to evolve, ATMs are constantly innovating to provide optimal services for customers. Today, ATMs are available in several types, each with different functions designed to meet various transaction needs.

Read on to learn more about the different types of ATM machines and their functions!

Types of ATM Machines

1. Cash Withdrawal ATM

This is the most commonly found type of ATM. Its primary function is to allow customers to withdraw cash.

As technology has evolved, these ATMs have also incorporated features that enable customers to perform various transactions beyond cash withdrawals, such as interbank transfers and bill payments.

2. Cash Deposit Machine (CDM)

A Cash Deposit Machine (CDM) is an ATM designed to accept cash deposits. This machine allows customers to deposit cash independently without having to visit a bank branch.

CDMs are also equipped with features that support various transactions, such as interbank transfers, bill payments, and e-money top-ups.

3. Cash Recycling Machine (CRM)

A Cash Recycling Machine (CRM) is a banking service innovation developed from ATM and CDM technology. Through this machine, customers can both withdraw and deposit cash efficiently.

CRMs also provide other transaction services, such as interbank transfers, education fee payments, bill payments, and mobile credit purchases.

4. Non-Cash ATM

As the name suggests, non-cash ATMs do not support cash transactions such as withdrawals or deposits. Instead, they are designed for non-cash transactions, such as interbank transfers and bill payments.

Cash Deposit Machine (CDM) vs. Cash Recycling Machine (CRM): What’s the Difference?

In general, the main difference between CDMs and CRMs lies in how cash is processed.

A CDM functions as a one-way cash deposit machine. This means that cash deposited into the machine cannot be dispensed to another customer for withdrawal.

Meanwhile, a CRM offers greater flexibility because it functions not only as a cash deposit machine but also as a cash withdrawal machine. Cash deposited into the machine is stored in a dedicated cassette and can be reused to fulfill cash withdrawal requests from other customers.
