As a cybersecurity expert, I get asked often about whether emerging technologies like digital wallets are safe to use. With data breaches so common now, it‘s smart to question any new service that requires sharing personal information online or connecting to your finances.
In this comprehensive guide, I‘ll explain exactly what digital wallets are, how they aim to protect your data, and the overall risks and rewards these payment tools create for both individual consumers and merchants.
Overview – Promising Paperless Payment Revolution
A digital wallet consists of a web or smartphone app that stores your debit/credit card information to enable quick online or offline payments without physically presenting your cards each time. By tapping or scanning your mobile device at checkout terminals, transactions can complete securely in seconds while still pulling funds directly from your bank.
Leading technology providers like Apple, Google, Samsung and PayPal have leveraged tokenization, encryption, biometrics and other security measures within their branded digital wallets to minimize risks of fraud or stolen data. Meanwhile billions in venture capital fuels startups striving to make these services the default payment option worldwide.
Industry research indicates consumers increasingly favor digital wallets over cash or plastic cards for most transactions thanks to speed, rewards incentives and habit formation around mobile device usage.
This guide will analyze the convenience benefits, security risks, unanswered questions and future predictions that make digital wallets one of the most pivotal emerging technologies on the planet despite their technical complexity.
How Do Digital Wallets Actually Work?
While the tap-and-pay experience of using a digital wallet seems simple, complex security infrastructure and partnerships enable this functionality.
I‘ll break down key technologies powering major digital wallets like Apple Pay, Google Pay and Samsung Pay:
Tokenization
Tokenization plays a vital role in digital wallet security by substituting sensitive payment credentials that would normally be transmitted with randomly generated numbers only recognized between your device and the merchants‘ systems.
For example, when adding a Visa card to Apple Pay, Visa generates a Token ID number that replaces your actual Visa card number. This token is then encrypted and stored in the secure element chip of your device.
When using Apple Pay in a supported store, your device transmits this encrypted token along with a dynamic security code to the store’s payment terminal. The terminal sends the token to Visa’s servers where it is matched to your actual card number and decrypted. Visa then approves or declines based on your account’s status and available balance.
The merchant never receives your actual credit card number, limiting risks from potential data breaches. This tokenization approach is critical for digital wallets to prevent payment card details being distributed to numerous endpoints.
End-to-End Encryption
All major digital wallets also leverage SSL and TLS encryption to scramble payment information in transit between apps, devices and payment terminals to prevent intercepted data being interpretable.
Apple advertises Apple Pay security as “so secure that Apple doesn’t know what you bought, where you bought it, or how much you paid for it." Thanks to encrypted tokens, payment details are hidden from Apple as well.
Biometric Authentication
Another key security feature available with Apple Pay, Google Pay and most major digital wallet providers is biometric authentication. Services like Apple‘s Face ID, Touch ID fingerprint recognition, Samsung‘s Iris scanning capability and Android‘s fingerprint APIs enable verified access to payment cards stored in your virtual wallet.
This prevents thieves from easily using your payment sources via digital wallets even if your phone is lost or stolen. App access history can pinpoint exactly when unauthorized transactions may have occurred as well.
NFC Transmission
When making contactless payments via digital wallets at retail stores, data is transmitted wirelessly over very short distances between your mobile device and payment terminals using near-field communication (NFC) chips and antennas.
Special signal modulation allows NFC to prevent interference or eavesdroppers. Typical transmission ranges under 4 inches provide inherent proximity protections against remote card data theft.
Of course you don‘t see all this security infrastructure working behind the scenes…just tap, scan or click payment confirmation.
Now that we‘ve covered the concealed technologies of digital wallets, let‘s explore their explosive growth.
Digital Wallet Adoption Stats
- Mobile contactless payments tripled from 2019 to 2022 to over $2 trillion worldwide according to Juniper Research.
- By 2024, an estimated 471 million global shoppers will use a mobile wallet according to eMarkerter’s data.
- 92 of the top 100 US merchants by annual revenue now accept contactless payments according to payments giant Visa.
As merchants ranging from mom-and-pop shops to retail giants increasingly support tap payments, Google Pay, Apple Pay and Samsung Pay have become the mainstream choices thanks to mobile market dominance. I‘ll overview the leading digital wallet contenders next.
