This is a very cool new product.
Researchers from The Hong Kong Polytechnic University (PolyU)'s Institute of Textiles and Clothing have recently developed "An intelligent Simulator for Cross-selling & Up-selling using Smart Fitting Room & Smart Dressing Mirror". It is envisaged to help fashion retailers boost business volume by improving sales and customer services.
This system uses the technology of Radio Frequency Identification (RFID) to detect items brought into a fitting room or placed in front of a dressing mirror. When an item is picked into the fitting room or placed in front of a dressing mirror, the product ID will be immediately detected and transmitted to the system through the antennae and reader.
