Lost the receipt for that diamond? No problem, just scan the barcode
In a world first, Hong Kong will offer customers a chance to have tiny barcodes inscribed by laser onto their jewellery - a hi-tech alternative to the information now contained on paper receipts.
The scheme is aimed at boosting consumer confidence in jewellery by making it easier to establish the origin and quality of the product.
The city's jewellery exports top US$4 billion a year, while gold jewellery and gemstones are major shopping draws for mainland tourists.
The system, which was five years in the making, was developed by the Hong Kong Jewellery Manufacturers' Association and is being implemented by the Productivity Council.
Although the hi-tech labelling system does not replace paper receipts, which contain important details about the product and the retailer, it does mean lost receipts no longer spell disaster for the customer.
A laser inscribes a special 3mm by 1mm barcode containing encrypted information about the product on the jewellery, such as on the inside of a ring. A mainland tourist for instance could then verify its authenticity.
