Stewart & Wu products are fitted with authentication tags bearing an ID number that is linked to the registered owners personal profile. Profiles  contain the owners photographic ID and a list of all the Stewart & Wu products that they have purchased.

A Stewart & Wu product can be quickly authenticated in two simple steps:

1.  Does the identity of the registered owner match that of the individual currently in possession of the product and;

2. Is the product correctly listed  

If the answer is 'yes' to both then the product is highly likely to be genuine.

If your mobile handset has a high-speed Internet connection it is possible to access image galleries associated with each product. A definitive authentication can then be made by comparing the product itself with images of the original.
