A small JavaScript/TypeScript utility library that identifies credit card brand types from full or partial card numbers, supporting type-as-you-go detection. It is not a validation library but a building block for payment forms and validation UIs.

Use cases

• detect credit card type from partial number as user types
• show correct card brand icon in a payment form
• identify card brand from a full card number
• build custom credit card validation logic
• handle ambiguous BIN prefixes like UnionPay vs Discover
• normalize card brand codes for CSS class names

When to choose

• you need lightweight, dependency-free card brand detection in Node or the browser
• you want type-as-you-go detection supporting partial numbers
• you need broad brand coverage including regional cards like Elo, Mir, Troy, Verve

When to avoid

• you need full card number validation (Luhn, expiry, CVV)
• you need payment processing itself rather than card type detection
• you need server-side BIN database lookups with issuer details
