The way Australians pay for everyday purchases is undergoing a quiet revolution. According to a recent analysis by the Reserve Bank, more than one in three people now use a digital wallet on their mobile device for in-person payments — a significant jump from just one in ten in 2019. As smartphone-based transactions become increasingly common, a critical question emerges: Are mobile payments truly safer than traditional methods?
This surge in adoption is driven largely by younger consumers, with over 60% of Australians aged 18 to 29 making at least one digital payment per week. While convenience plays a major role, security is proving to be just as compelling a factor.
The Rise of Digital Wallets: Convenience Meets Security
Digital wallets like Apple Pay, Google Pay, and others are no longer niche tools — they're becoming central to how people manage money. Andrew Morrison, Chief Product and Growth Officer at Ubank, attributes this shift to two powerful drivers: convenience and enhanced security.
"What started as a hygiene concern during the pandemic has evolved into a fundamental change in consumer behavior," Morrison explains. "People want fast, seamless transactions — and they want them to be safe."
Ubank saw a 34% spike in digital wallet usage during December 2022 alone, coinciding with the holiday shopping season. The appeal? Carrying multiple cards in one device, making purchases with a single tap or QR scan, and doing so with added layers of protection.

How Secure Are Mobile Payments?
While physical cards still dominate in-person payments overall, contactless smartphone payments are rapidly closing the gap — and many experts argue they offer superior security.
Biometric Authentication: Your Face or Fingerprint as a Lock
One of the biggest advantages of digital wallets is biometric authentication. Instead of relying on easily forgotten or guessed PINs, users can unlock payments using fingerprint or facial recognition technology. This ensures that only authorized individuals can access stored payment information.
"Digital wallets eliminate the need to carry physical cards that can be lost or stolen," says Morrison. "They also reduce the risk of card skimming at payment terminals."
Tokenization: Your Real Card Number Stays Hidden
Beyond biometrics, digital wallets employ tokenization — a cybersecurity technique that replaces your actual credit card number with a unique, one-time-use virtual number during transactions.
Dr. Arash Shaghaghi, Senior Lecturer in Cybersecurity at the University of New South Wales (UNSW), explains:
"Apple Pay, for example, uses a device-specific number and generates a unique transaction code every time you make a purchase. Your real card details are never shared with merchants."
This means even if a hacker intercepts transaction data, they won’t gain access to your actual card information — significantly reducing the risk of fraud.
Digital Wallets vs. Virtual Cards: What’s the Difference?
While digital wallets are gaining popularity, another innovation is emerging: virtual cards. These are not simply digital versions of physical cards but standalone payment instruments generated within an app, each with its own card number and CVV.
Unlike digital wallets, virtual cards often allow users to:
- Set spending limits
- Generate single-use card numbers
- Create merchant-specific cards (e.g., one for Netflix, another for Amazon)
Shaghaghi notes that while digital wallets offer strong security, they currently lack the granular control provided by virtual cards offered directly by financial institutions.
"Virtual credit cards give users more privacy and customization," he says. "And interestingly, services like Google Pay and Apple Pay now support integrating these virtual cards — combining the best of both worlds."

How to Keep Your Digital Wallet Safe: Expert Tips
With rising usage comes increased responsibility. Dr. Kam-Fung Cheung, Cybersecurity, Risk, and Privacy Lecturer at UNSW, offers practical advice for protecting your digital wallet:
- Enable all available security layers: Use passcodes, biometrics (fingerprint or face ID), and multi-factor authentication (MFA) whenever possible.
- Download apps only from official stores: Stick to trusted sources like the App Store or Google Play to avoid counterfeit apps.
- Keep software updated: Regularly install updates for your phone’s operating system and wallet app to patch known vulnerabilities.
- Avoid public Wi-Fi for transactions: Unsecured networks can expose your data to eavesdropping. Use mobile data or trusted private networks instead.
- Monitor transaction history: Review recent activity frequently to catch any unauthorized charges early.
- Watch out for phishing scams: Never share wallet credentials or card details via email, text, or unknown websites.
- Don’t share sensitive info: Even with friends or family, avoid disclosing login details or authentication methods.
These steps may seem basic, but they form the foundation of robust personal cybersecurity.
Frequently Asked Questions (FAQ)
Q: Can someone steal my money if my phone is lost or stolen?
A: It’s highly unlikely if your phone is locked with a passcode, biometrics, or MFA. Most digital wallets require authentication before each transaction. You can also remotely lock or wipe your device using built-in tools like Find My iPhone or Android Device Manager.
Q: Do digital wallets work without internet access?
A: Yes. NFC-based payments (like tapping your phone) don’t require an active internet connection. However, you may need connectivity to add new cards or view transaction history.
Q: Are all merchants accepting mobile payments?
A: Most major retailers and small businesses in Australia now support contactless payments via smartphones. However, some older terminals may only accept physical cards or lack NFC capabilities.
Q: Is it safe to store multiple cards in one wallet?
A: Yes — digital wallets encrypt stored card information and use tokenization per transaction. Just ensure your device itself is secured with strong authentication.
Q: Can I get a refund if a fraudulent transaction occurs?
A: Absolutely. Like traditional card payments, most banks and card issuers offer fraud protection for unauthorized transactions made through digital wallets.
Q: Will digital wallets replace physical cards completely?
A: While adoption is growing fast, full replacement isn’t imminent. Physical cards remain essential for certain situations (e.g., car rentals, international travel). However, digital wallets are increasingly becoming the default choice for daily spending.
Final Thoughts: A Safer Future for Everyday Payments?
Digital wallets are more than just a trend — they represent a shift toward smarter, more secure financial habits. With features like tokenization and biometric verification, smartphone payments often provide stronger protection than swiping or inserting a physical card.
That said, no system is foolproof. User behavior remains a critical factor in maintaining security. By combining advanced technology with responsible habits — such as avoiding public Wi-Fi and monitoring accounts regularly — consumers can enjoy both convenience and peace of mind.
As virtual cards and institutional integrations evolve, we’re likely to see even greater customization and control over how we spend and protect our money.
