Cashless Payments, E-Wallets, and Digital
Banking:
How Convenient Is Convenient Enough?
A student buys coffee with a QR code, transfers money to a classmate
through a banking app, and pays an electricity bill through an e-wallet. For
many young consumers, these activities feel ordinary. Cashless payment is no
longer a future trend; it is part of daily financial life. In Vietnam, NAPAS
reported that its system processed 9.56 billion transactions in 2024, about 30%
more than in 2023, reflecting strong use of fast transfers, QR payments,
e-wallets, cards, and mobile financial services (NAPAS, 2025).
For students of Finance, Banking, and Financial Technology, digital
payment is more than a convenient way to pay. It is changing how institutions
serve customers, assess risk, protect transactions, and compete. The key
question is not whether people will use digital payments. The more important
question is how far convenience can go without weakening safety, privacy,
fairness, and consumer trust.
Why Digital Payments Are Expanding So Quickly
Digital payments solve real problems. They reduce the need to carry
cash, make bill payment and online shopping easier, and help small merchants
accept payment at low cost. A QR code can connect a customer and merchant
within seconds; an e-wallet can combine payment, shopping, transport, and
loyalty services in one application. Digital banking allows customers to check
balances, transfer funds, and receive support without visiting a branch. The
World Bank’s Global Findex 2025 links digital connectivity with wider financial
inclusion, because mobile technology can expand access to accounts, payments,
savings, and other financial services (World Bank, 2025). NAPAS also notes that
QR payments, contactless payments, biometric authentication, and integrated e-wallet
solutions are expanding quickly in Vietnam (NAPAS, 2026).
Convenience Has a Hidden Cost: The Fraud Risk
The same speed that makes digital payment attractive can create risk. A
fraudster may use a fake banking website, impersonation call, malicious QR
code, phishing message, or remote-control application to persuade a victim to
approve a transfer. The attack often succeeds not because criminals defeat a
bank’s technology, but because they create fear and urgency: “Your account is
locked,” “You must verify your identity,” or “Transfer money to a safe
account.” Once the payment is completed, funds may move quickly across several
accounts, making recovery difficult.
Digital security is therefore a shared responsibility. Customers should
protect passwords, authentication codes, devices, and transaction approvals.
Banks and fintech firms should use clear warnings, strong authentication,
transaction monitoring, fraud-response procedures, and secure product design.
In Vietnam, banks and payment intermediaries began implementing biometric
authentication from July 1, 2024 under measures referenced by NAPAS and the
State Bank of Vietnam, intended to enhance the security and confidentiality of
online payments (NAPAS, 2025).
Security by Design: What Should Banks and
Fintech Firms Do?
Authentication is important, but it is not enough when a customer has
been manipulated. Payment providers also need to look for warning signals: a
new beneficiary, a sudden high-value transfer, a new device, unusual timing, or
a pattern that differs sharply from normal behaviour. These signals can trigger
a warning, a verification step, or a short delay. In Project Hertha, the Bank
for International Settlements tested payment-system analytics on simulated data
and found that they could help identify 12% more illicit accounts; when
detecting previously unseen criminal behaviour, the improvement was 26%. The
BIS also stressed that analytics are only a supplementary tool and must be
supported by good governance, privacy protection, and practical procedures (BIS,
2025).
The responsibility question is not simple. Customers must be careful,
but no individual can be expected to understand every cyber threat or detect
every well-designed scam. Banks control the payment interface, observe
transaction data, and have the technical capacity to identify abnormal
patterns. Telecom providers may help block suspicious messages and calls.
Regulators can require common security standards and define clear
responsibilities when fraud occurs. The fairest system is one in which each participant
takes responsibility for the risks it can realistically control.
How Much Responsibility Should the Customer
Bear?
Customers should take reasonable precautions: use official banking
applications, verify unexpected requests through official channels, check
recipient information before confirming transfers, and report suspicious
activity immediately. However, customer responsibility has limits. Safe
behaviour should be the easiest behaviour. A warning should be understandable,
not hidden in a long list of terms. A payment interface should make accidental
transfers to a new beneficiary less likely. A bank should not design for
maximum speed only; it should design for customer protection as well.
Students should also recognise that trust is a commercial asset. A
payment app that is simple but unsafe may grow quickly at first, yet it will
lose customers if fraud incidents are handled poorly. Conversely, a system that
blocks every unusual payment will frustrate legitimate users. The professional
challenge is to balance security and convenience through risk-based controls:
stronger checks when risk is high, but a smooth experience when risk is low.
This balance requires finance knowledge, customer empathy, data skills, and
ethical judgement.
Will E-Wallets and Fintech Replace
Traditional Banks?
E-wallets and fintech platforms are unlikely to replace traditional
banks completely. Banks still play central roles in deposits, credit, payment
settlement, compliance, and consumer protection. Fintech firms often add speed,
specialised user experience, and new distribution models. The likely future is
an integrated ecosystem in which banks, payment intermediaries, technology
providers, and platform businesses cooperate and compete. The BIS has noted
that tokenisation, transaction-risk indicators, fraud registries, and
cooperation across institutions can improve fraud prevention, although
coordination becomes more difficult when payments cross different providers and
jurisdictions (BIS, 2026).
A Practical Safety Checklist for Students
Ø Use only official banking and e-wallet
applications downloaded from trusted app stores.
Ø Treat any request for a password, OTP,
biometric confirmation, or remote-control installation as suspicious until
verified through an official channel.
Ø Check the recipient name, account number, and
payment amount before confirming a transfer.
Ø Enable transaction alerts and contact the
provider immediately when an unfamiliar transaction appears.
Ø Do not let convenience create haste: pause
and verify when a request creates fear, urgency, or pressure.
For students, this transformation creates opportunities in digital
banking, payment operations, fraud prevention, compliance, data analytics,
cybersecurity, product management, and financial education. The essential
capability is to understand both the financial logic of payment systems and the
human behaviour that can make them safe or unsafe. Cashless payment can make
financial life more inclusive, efficient, and innovative. Yet convenience
should never mean carelessness. The finance professionals of the future must
build services that are fast and attractive, but also secure, understandable,
inclusive, and worthy of public trust.
