UNITED STATES OF AMERICA
For shopping on websites or apps, you’ll typically use one of two methods: direct merchant payments or third-party platforms.
1.1 Direct Payment on Merchant Websites/Apps
Most e-commerce sites (e.g., brand stores, marketplaces) let you enter card details directly at checkout.
- **Steps**:
1. At the checkout page, select “Credit Card” or “Debit Card” as your payment method.
2. Enter your card details **accurately**:
- Card number (16–19 digits, no spaces).
- Expiration date (month/year, e.g., 12/25).
- CVV code (3-digit code on the back of Visa/Mastercard; 4-digit on American Express).
- Billing address (must match the address registered with your bank—even small differences, like abbreviations, can cause payment failures).
3. Complete extra verification (if required):
- 3D Secure (3DS): Enter a one-time code sent to your phone/email (used by banks like CCB to prevent fraud).
- SMS verification: Some merchants send a code to confirm your identity.
4. Review your order (amount, shipping address) and click “Pay” or “Confirm.”
5. Save the confirmation email/receipt for future reference.
1.2 Via Third-Party Platforms (PayPal, Google Pay)
Third-party services add an extra layer of security (they don’t share your card details with merchants).
Example 1: PayPal (No Account Required)
Many merchants (e.g., Justway) support PayPal’s “Guest Checkout”
