The bech32 format is a favorite of mine because it uses an alphabet that's designed to be unambiguous and its checksum is designed specifically to guarantee catching few character mistakes and make it possible to suggest where the mistake likely is. It also has a builtin human-readable purpose prefix at the front. Since it's all lowercase it also fits into the QR alphanumeric mode, which doesn't support mixed case so QR codes of bech32 IDs are more efficient.

An error-correction code inside the ID?! I love it.
