Worked example
Generate several sample entries to test spacing and validation messages in a payment-form prototype.
Does checksum validation prove an account exists?
No. It checks structure and arithmetic, not ownership, account existence or ability to receive funds.
Can I use generated values for real transfers?
No. Use them only in isolated tests. Do not submit them to live payment systems or assume they cannot coincide with real details.
