Supported Brands

Generate

Rust

#![allow(unused)]
fn main() {
use rand::thread_rng;
use idsmith::credit_card::GenOptions;

let mut rng = thread_rng();
let registry = idsmith::credit_cards();

// Random brand
let card = registry.generate(&GenOptions::default(), &mut rng).unwrap();

// Specific brand
let opts = GenOptions { brand: Some("visa".to_string()) };
let visa = registry.generate(&opts, &mut rng).unwrap();
// visa.brand     → "VISA"
// visa.number    → "4152839405126374"
// visa.formatted → "4152 8394 0512 6374"
// visa.cvv       → "123"
// visa.expiry    → "09/28"
}

Python

import idsmith

card = idsmith.CreditCard.generate()           # random brand
visa = idsmith.CreditCard.generate(brand="visa")  # specific brand
print(visa["formatted"])  # 4152 8394 0512 6374
print(visa["cvv"])        # 123
print(visa["expiry"])     # 09/28

JavaScript

const { CreditCard } = require('idsmith');

const card = CreditCard.generate();        // random brand
const visa = CreditCard.generate('visa');  // specific brand
console.log(visa.formatted);  // 4152 8394 0512 6374
console.log(visa.cvv);        // 123
console.log(visa.expiry);     // 09/28
