Bankster

Helps validating IBAN account numbers and BIC numbers. Thats all for the great language Elixir.

Installation

The package can be installed as Hex package:

Add bankster to your list of dependencies in mix.exs:

def deps do
  [{:bankster, "~> 0.3.0"}]
end

Run mix deps.get to fetch the package from hex

Usage

Validate IBANs

You can either use Bankster.iban_valid?/1 or Bankster.Iban.valid?/1 to validate IBANs.

iex> Bankster.iban_valid?("NOTVALID")
false

iex> Bankster.Iban.valid?("NOTVALID")
false

Validation with errors

Beside the boolean validation function, Bankster offers a validation function which returns the corresponding error. Like the other validation, you can use Bankster.iban_validate/1 or Bankster.Iban.validate/1 to validate IBANs.

iex> Bankster.iban_validate("NOTVALID")
{:error, :invalid_country}

iex> Bankster.Iban.validate("DK8387188644726815223423423423423423423")
{:error, :invalid_length}

iex> Bankster.Iban.validate("DK83 8718 8644 7268 15")
{:ok, "DK8387188644726815"}

Validate BICs

Validating BICs works the same way as already shown for IBANs. So you can either use Bankster.bic_valid?/1 or Bankster.Bic.valid?/1 to validate BICs.

iex> Bankster.bic_valid?("NOTVALID")
false

iex> Bankster.Bic.valid?("NOTVALID")
false
