 Ibandit is a Ruby library for manipulating and validating

 For example:
 - Sweden does support IBANs (**1.**) but the format is ambiguous due to variable length account numbers so they cannot be deconstructed (**2.**). For persistence, we therefore recommend using pseudo-IBANs (**3.**) because the national banking details can be recovered from them.
