How do these Digital Wallet applications work?

Downloading and setting up the App

To start using a digital wallet app, you first need to download it from your device's app store. Popular options include Apple Pay, Google Pay, Samsung Pay, and apps from your bank. After downloading, you'll go through a setup process which includes adding your name, and contact info, and verifying your identity. The app will guide you through the steps.

Storing Payment Information

A key feature of digital wallets is the ability to store your payment information for faster checkout. You can add your credit, debit, and gift cards by entering the card numbers manually or scanning them with your phone's camera. Your information is encrypted for security. Many apps also let you add loyalty cards, coupons, and tickets.

Security Measures

Digital wallets utilize various security measures like two-factor authentication, fingerprint or facial recognition, and PIN codes to protect your money. When entering your card details, the actual numbers are not stored - only a unique token representing your card is saved. This prevents your real card details from being accessed if your phone is compromised.

Making Payments

When you're ready to pay with your digital wallet, simply unlock your phone and hold it near the store's contactless payment terminal. Thanks to NFC technology, your info is transmitted securely. Many apps allow you to select which card to use if you have multiple added. You may need to verify with a PIN or biometrics.

Transaction History and Budgeting

Digital wallets provide transaction history so you can track your spending. Some apps offer additional budgeting features, spending insights, and expense categorization. Being able to see all your transactions in one place makes it easy to monitor your money.

Different types of payment method you can add to in wallet

Near field communication, or NFC:

This allows two devices to exchange information if they’re placed close to each other. Apple Pay and Google Pay use this technology.

The NFC technology is prevalent due to its contactless nature. With NFC the users can make payments by adding a NFC-enabled card or activating the NFC feature in the wallet. NFC payments can be made by bringing the digital wallet-enabled mobile device in close proximity with the payment terminal and the payment is made instantly.

Magnetic secure transmission, or MST:

This generates a magnetic signal, much like when you swipe the magnetic stripe on a credit card.

This emulates the magnetic strip on a traditional credit or debit card. It allows payments to be made by waving the smartphone near the card reader, even on terminals without NFC. Samsung Pay uses MST technology.

QR codes:

These are barcodes you can scan with your smartphone’s camera. In the PayPal app, for example, you can generate a QR code that lets you use your account to pay for an item in a store.

QR payments are another instant payment method available in a digital wallet app. Here, the user can make payments by scanning a QR code and making purchases conveniently and efficiently in real time.
