Safer alternatives and recommended approaches

Secure implementation practices
: Validates the checksum digit to ensure the number sequence is mathematically possible. BIN/IIN Identification
$pan = sanitize_pan($raw_pan); if ($pan === '') http_response_code(400); echo json_encode(['error' => 'No PAN provided']); exit;
The following example demonstrates the most important part of this process: creating a PaymentIntent with a minimal amount:
