use Takashato\VietQr\Enums\Bank;

// Static QR - customer enters amount
$qr = VietQrCode::bankAccount(Bank::VIETCOMBANK, '0011012345678');

// Get QR string (for your own rendering)
$qrString = $qr->build();

// Generate SVG
$svg = $qr->generateQr('svg', 300);

// Generate Base64 PNG
$base64 = $qr->generateQrBase64('png', 300);

Dynamic QR with Amount

use Takashato\VietQr\VietQrCode;
use Takashato\VietQr\Enums\Bank;

// Dynamic QR - fixed amount of 180,000 VND
$qr = VietQrCode::bankAccount(
    bank: Bank::TECHCOMBANK,
    accountNumber: '19033123456789',
    amount: 180000,
    purpose: 'Thanh toan don hang #12345'
);

echo $qr->build();

Card Transfer QR

    amount: 50000
);

        $merchant
            ->setService(Service::NAPAS_BY_ACCOUNT)
            ->setAcquirerId('970436')  // Vietcombank BIN

use Takashato\VietQr\Enums\Bank;

// Get bank BIN code
$bin = Bank::VIETCOMBANK->value; // '970436'

// Get bank names
$shortName = Bank::VIETCOMBANK->shortName(); // 'Vietcombank'
$fullName = Bank::VIETCOMBANK->nameVi(); // 'Ngân hàng TMCP Ngoại thương Việt Nam'

// Find bank by BIN
$bank = Bank::fromBin('970436'); // Bank::VIETCOMBANK

// Search banks
$results = Bank::search('viet'); // Returns matching Bank enums
