The standard wallet has undergone a significant transformation in recent years — from a tangible cash and card holder to an app that stores bank and credit card details that can be used to make purchases via a smart device.
This article includes tips, suggestions and general information. We recommend that you always do your own research and consider getting independent tax, financial and legal advice before making any important decision.
Convenient, secure, and easy to use, digital wallets have become a popular payment method worldwide, accounting for nearly half of all global ecommerce sales.1
What is a digital wallet?
A digital or e-wallet is a payment tool, usually in the form of an app, that facilitates purchases using a smartphone, smartwatch, or other digital device.
Digital wallets store financial data and can make transactions quick and simple. They remove the need to carry around physical cards or money, should one choose to take this path.
How does a digital wallet work?
To make a purchase, a digital wallet communicates stored credit card or bank details to the vendor’s point of sale system, either through a magnetic signal or the device’s Bluetooth or Wi-Fi connection.
Unique tokens are used to create one-time transaction numbers for each purchase. They’re encrypted to help protect the user’s data and then processed and communicated to the relevant card institutions and banks.
Digital wallets usually work through the following technologies:
- Quick response (QR) codes: QR codes are bar codes that can be linked and read through a smartphone camera. Some digital wallets also allow users to set up unique individual QR payment codes, which can be read by a vendor’s point-of-sale device or platform.
- Near field communication (NFC): NFC is where two smart devices connect closely through electromagnetic signalling (i.e., when tapping a smartphone to a merchant’s point-of-sale register).
- Magnetic secure transmission (MST): This is similar to the technology used by magnetic card readers when a credit or debit card is swiped through a point-of-sale device — only the encrypted magnetic field is generated by the smart device.
What else can a digital wallet be used for?
In addition to streamlining payments, digital wallets can be used to store:
- Loyalty cards
- Gift cards
- Membership cards (e.g., for fitness and leisure centres)
- Coupons
- Event tickets
- Plane tickets
- Boarding passes
- Hotel reservations
- Personal IDs
Examples of a digital wallet
Depending on the type of digital wallet, there are different formats and levels of access, including:
- Closed: A business offering goods or services may provide a closed wallet, which limits transactions to that particular business.
- Open: Open wallets are issued by banks or financial institutions and can be used to make purchases with any merchant that supports the technology — online, contactless in-store, or for cashback and at ATMs.
- Semi-closed: Semi-closed wallets allow you to make purchases with a select list of merchants and businesses that are uniquely affiliated or contracted with the particular wallet issuer.
- PayPal Digital Wallet: This digital wallet can store bank account information and debit and credit cards in one place for easy online and in-store payments.
Potential benefits of a digital wallet
From quick payments and hassle-free transactions to keeping information organised and accessible, digital wallets can offer benefits. Below are some examples:
- Efficiency: Digital wallets store financial information for convenient access, allowing users to transact in real time without a physical wallet.
- Contactless: Make purchases easily and securely without physically handling cash or cards.
- Safe and secure: Encrypted data and one-time payment tokens can create secure transactions, so full bank data, card numbers and ID details are not exposed. Many apps also utilise one-time PINs and two-factor authentication.
Are there cons of digital wallets?
Though generally safe, it’s important to consider potential drawbacks of digital wallets. These could include:
- Universality: Depending on the access type of the wallet app, it may not be accepted at all locations.
- Connectivity: Digital wallets require a strong Bluetooth or Wi-Fi signal, functioning mobile data, and a well-charged device.
- Protection: Though unlikely, a user’s digital data can be vulnerable if the mobile device is stolen and not protected.
