In the world of banking and financial services, you’ve likely encountered the term KYC verification. Whether you're opening a bank account, investing in stocks, or signing up for a cryptocurrency exchange, completing KYC (Know Your Customer) is often a mandatory step. But what exactly is KYC? Why is it so important? And how does it protect both users and institutions?
This guide breaks down everything you need to know about KYC — from its core purpose and real-world applications to best practices and security benefits — all while aligning with global financial compliance standards.
What Does KYC Mean? Understanding “Know Your Customer”
KYC, or Know Your Customer, is a standard identity verification process used by financial institutions to confirm the identity of their clients. The primary goal of KYC is to prevent fraud, money laundering, and unauthorized access by ensuring that every user is who they claim to be.
At its heart, KYC helps organizations:
- Verify user identity
- Assess the legitimacy of fund sources
- Determine whether a customer is suitable for specific financial products or services

The concept of KYC originated in 1998, when the Basel Committee on Banking Supervision released a statement titled "On Preventing Criminals from Using the Banking System to Launder Money." This landmark document laid the foundation for modern anti-money laundering (AML) policies, requiring banks to implement strict customer identification procedures, comply with transaction laws, and cooperate with law enforcement.
Today, KYC is a cornerstone of financial regulation worldwide — ensuring safer, more transparent digital transactions.
Why Is KYC So Important?
For individual users, providing accurate KYC information ensures smooth registration and uninterrupted access to financial tools. Skipping or falsifying details can lead to rejected applications or frozen accounts.
For financial institutions, failing to enforce proper KYC procedures can result in severe consequences — including legal penalties, regulatory fines, license revocation, and reputational damage.
KYC isn’t just a formality; it's a critical safeguard in today’s interconnected financial ecosystem.
Key Reasons for Conducting KYC Verification
KYC verification is now standard across nearly all regulated financial platforms. From traditional banks to digital payment apps and crypto exchanges, verifying user identity has become essential. Here’s why:
1. Prevent Financial Crimes
One of the original purposes of KYC was to stop criminals from hiding illicit funds within the financial system. By requiring verified personal data — such as government-issued IDs, proof of address, and facial recognition — institutions can trace ownership and detect suspicious activity.
In regions like Taiwan, the Financial Supervisory Commission (FSC) enforces strict KYC-related regulations through laws such as the Anti-Money Laundering Act. All licensed institutions — including banks, securities firms, insurance companies, and credit card providers — must follow these rules. Non-compliance can lead to heavy fines or operational suspension.
2. Protect User Security
The financial sector handles vast amounts of sensitive data and assets. KYC adds an essential layer of protection by:
- Preventing identity theft and fraudulent account openings
- Blocking unauthorized loan applications
- Reducing risks associated with money laundering and terrorist financing
- Creating a safer environment for personal data and asset management
3. Evaluate Risk Tolerance
Before offering investment products — such as mutual funds, ETFs, bonds, or structured notes — many institutions require customers to complete a KYC questionnaire. This assesses your:
- Investment experience
- Financial goals
- Risk tolerance level
These insights help advisors recommend suitable products and ensure investors don’t take on more risk than they can handle. Additionally, users are often required to update their KYC profile periodically; failure to do so may restrict future trading activities.
5 Common Scenarios Where KYC Verification Is Required
KYC processes are widely adopted across various industries. Below are five major sectors where KYC plays a crucial role.
1. Banking Services
Common use cases: Opening bank accounts (digital or physical), applying for credit cards, securing loans, domestic or international wire transfers
When opening a digital bank account, for example, users typically submit official ID documents and undergo facial verification. This prevents identity fraud and ensures compliance with financial regulations.
For private banking clients with high-net-worth portfolios, KYC checks are even stricter — often requiring detailed documentation of income sources and asset history.
2. Securities, Funds, and Trading Platforms
Common use cases: Stock brokerage registration, mutual fund sign-ups, futures/options trading, overseas brokerage accounts
Platforms use KYC to verify eligibility and ensure investors understand the risks involved. Many require periodic updates to risk assessment questionnaires.
Take one of the world’s leading online brokers: robust security features like two-factor authentication (2FA) combined with thorough KYC checks help protect user accounts from breaches and unauthorized access.

3. Insurance Providers
Common use cases: Online policy purchases, claims processing, beneficiary verification
Insurance companies use KYC to confirm applicant identities and evaluate risk profiles. This helps prevent fraudulent claims — such as multiple high-value policies taken out in a short period.
For instance, when purchasing overseas travel insurance, users must provide age, ID number, and coverage amount. Local regulations may limit payout amounts for minors (e.g., NT$690,000 for children under 15) to deter misuse.
4. Digital Payment & Fintech Services
Common use cases: Mobile wallets (Line Pay, JKO Pay), cross-border payment platforms (Wise, PayPal)
These services handle frequent transactions and international transfers, making them potential targets for money laundering. Like banks, they follow strict KYC protocols under supervision from national regulators.
Platforms like Wise operate under the UK’s Financial Conduct Authority (FCA), one of the strictest regulatory bodies globally. They separate customer funds from company funds, use HTTPS encryption, and enforce dual authentication via email and SMS — all supported by rigorous KYC checks.
5. Cryptocurrency Exchanges
Common use cases: Exchange registration, depositing fiat currency, withdrawing funds, large transaction reviews
Due to the pseudonymous nature of blockchain transactions, crypto exchanges apply multi-tiered KYC levels to manage risk:
- Basic Level: Strong password + 2FA
- Intermediate: ID upload + facial recognition → enables trading and limited withdrawals
- Advanced: Proof of address + income verification + possible video call → unlocks higher limits, P2P trading, and diverse deposit/withdrawal methods
This tiered approach balances accessibility with compliance and security.
