+
+ eval {
+ my $qr_image = SL::Helper::QrBill->new(
+ \%biller_information,
+ \%biller_data,
+ \%payment_information,

+
+=head1 DESCRIPTION
+
+This module generates the Swiss QR-Code with data provided to the constructor.
+
+=head1 METHODS
+
+=head2 C<new>
+
+Creates a new object. Expects five references to hashes as arguments.
+
+The hashes are structured as follows:
+
+=over 4
+
+=item C<%biller_information>
+
+Fields: iban.
+
+=over 4
+
+=item C<iban>
+
+Fixed length; 21 alphanumerical characters, only IBANs with CH- or LI-
+country code.
+
+=back
+
+=item C<%biller_data>
+
+Fields: address_type, company, address_row1, address_row2 and countrycode.
+
+=over 4
+
+=item C<address_type>
+
+Fixed length; 1-digit, alphanumerical. 'K' implemented only.
+
+=item C<company>
+
+Maximum of 70 characters, name (surname allowable) or company.
+
+=item C<address_row1>
+
+Maximum of 70 characters, street/nr.
+
+=item C<address_row2>
+
+Maximum of 70 characters, postal code/place.
+
+=item C<countrycode>
+
+2-digit country code according to ISO 3166-1.

+
+Fields: amount and currency.
+
