Cara Menggunakan NFC: Cek Saldo ATM hingga Top Up e-Money

NFC, or Near Field Communication, is a technology that allows devices to communicate with each other when they are in close proximity. This technology has revolutionized various aspects of our lives, including how we make payments, access information, and even connect with other devices. In this article, we will explore the different ways you can use NFC, from checking your ATM balance to topping up your e-money. So, let’s dive in!

What is NFC?

NFC is a short-range wireless communication technology that enables the exchange of data between two devices. It operates at a frequency of 13.56 MHz and allows devices to establish a connection simply by bringing them close together, usually within a few centimeters. NFC is widely used in contactless payment systems, access control, and data transfer between devices.

How does NFC work?

NFC works by utilizing electromagnetic induction, which allows for the exchange of data between two devices when they are in close proximity. There are two main modes of operation when it comes to NFC: passive mode and active mode.

In passive mode, one device, known as the reader or initiator, generates an electromagnetic field that powers the second device, known as the tag or target. The tag then responds to the reader’s commands and exchanges data accordingly. This mode is typically used in contactless payment systems, where the reader is a payment terminal and the tag is a contactless card or mobile phone.

In active mode, both devices generate their own electromagnetic fields. This allows for more complex interactions between devices, such as peer-to-peer data transfer or device pairing. Active mode is commonly used for sharing information between smartphones, exchanging files, or connecting to other devices, like Bluetooth speakers or smartwatches.

Using NFC to Check Your ATM Balance

One of the most convenient features of NFC is the ability to check your ATM balance using your mobile phone. This eliminates the need to visit an ATM or log in to your online banking platform. To check your balance using NFC, follow these steps:

Ensure that your mobile phone has NFC capabilities. Most modern smartphones are equipped with NFC.
Open the NFC settings on your phone and make sure the feature is enabled.
Download and install a compatible NFC banking application on your phone.
Launch the banking application and follow the on-screen instructions to set it up.
Place your phone near the NFC reader on the ATM machine. The reader is usually located on the side or front of the machine.
Follow the prompts on your phone’s screen to authenticate the transaction and check your balance.

Checking your ATM balance using NFC is not only convenient but also secure. Since the transaction is encrypted and requires authentication, the risk of unauthorized access to your account is significantly reduced.

How to Add NFC to a Non-NFC Phone for Virtual Transactions

If your phone does not have NFC capabilities, don’t worry! There are several ways to add NFC functionality to your non-NFC phone, allowing you to enjoy the benefits of virtual transactions. Here are three methods you can try:
