FAQ

• Are generated cards usable for real payments?
  • No. They are for testing only. Luhn passes, but accounts are fake.
• How to specify card type?
  • Use cc({ type }) with visa/mastercard/amex. See cc_type for supported types.
• Do money helpers support decimals?
  • Constrain ranges and formatting via options (implementation-specific).
