taiwan-id

This package provides a Haskell implementation of Taiwan's uniform identification number format.

This number format is used by both National Identification Cards (國民身分證) and Resident Certificates (居留證) issued by the Republic of China (ROC) government to individuals, with numbers assigned under each system occupying disjoint parts of the same identifier space.

Each identification number consists of a single uppercase letter followed by nine decimal digits, with the final digit serving as a checksum calculated according to a standard algorithm.

Example: A123456789

This package offers functions for validating, decoding, and encoding these numbers.
