Visa Technology Intelligence

What is Visa?

Visa Inc. is a global payments technology company that operates one of the world's largest electronic payment networks. Rather than issuing cards directly, Visa provides the infrastructure, technology, and network that enables financial institutions to offer Visa-branded cards and merchants to accept payments.

For e-commerce, Visa provides the rails for card-not-present transactions, security protocols like 3D Secure (Verified by Visa), and tokenization services. When a website accepts Visa, it means transactions are processed through Visa's global network of acquiring banks and payment processors.

Detection of Visa acceptance indicates standard credit/debit card processing capability. Virtually all payment gateways and processors support Visa, making it essential for any e-commerce operation serving customers in over 200 countries.

Visa Code Examples

Card Number Validation

// Visa card number detection
function isVisaCard(cardNumber) {
    // Visa cards start with 4 and are 13 or 16 digits
    const visaRegex = /^4[0-9]{12}(?:[0-9]{3})?$/;
    return visaRegex.test(cardNumber.replace(/\s/g, ''));
}

// Luhn algorithm validation
function validateCardNumber(number) {
    let sum = 0;
    let isEven = false;

    for (let i = number.length - 1; i >= 0; i--) {
        let digit = parseInt(number[i], 10);

        if (isEven) {
            digit *= 2;
            if (digit > 9) digit -= 9;
        }

        sum += digit;
        isEven = !isEven;
    }

    return sum % 10 === 0;
}

});

if (threeDSecureResult.error) {
    // Handle authentication failure
