A method for interfacing a point of sale system to a tax refund system. The method comprises generating a 2D code, such as QR code, corresponding to a sale transaction, the 2D codeencoding at least transaction information for tax refund purposes. The 2D code is output 300 and subsequently; scanned by a scanner 310. The 2D code is decoded into a data stream and a tax refund form 320 is generated and output based on the data stream. The 2D code may be output by printing, displaying or by sending to parties. The interfacing of the POS to tax refund system is done offline which can simplify the POS and infrastructure requirements. |
