Abstract
The security of invoices as between purchaser and supplier may be improved by printing a data matrix symbol or other glyph on the invoice. The data matrix contains two layers or portions of data. The first layer or portion contains invoice data and the second layer or portion contains secure data relating to the purchaser and supplier. This may include a trusted supplier status, a trusted supplier code and a unique voice identifier, or a reference thereto. On receipt of the invoice by the purchaser the data matrix is scanned and the trusted supplier status and supplier codes retrieved. These may be compared against a store of codes and status to verify the invoice as authentic. The secure data or a reference to the secure data may be re-encoded into a data matrix which may be affixed to a remittance advice sent by the purchaser to the supplier.
