"connected" product is a physical product which has been made interactive by a label containing a QR code or an NFC chip, i.e. by a so-called "smart tag". By scanning the code or placing their smartphones close to the chip, consumers are directed to a site that offers services, such as the authenticity verification service, or content, such as a video of the latest fashion show, or information regarding sustainability.

A connected product is a digital channel capable of creating interaction between a brand and consumers. Using this technology, the brand can convey information, content and services designed specifically for a given product.

A "smart tag" is a label, a hangtag or any other medium containing a QR code or an NFC chip. A smart tag makes a physical product interactive or, in other words, “connected”.

Smart tags are usually sewn onto a garment or simply attached to the packaging of a product. Depending on the product and the choices of the brand, it can be found inside a garment, on a bag, on the tongue of a shoe, on a perfume bottle, on the temple of a pair of glasses, on a watch, etc.

Smart tags that allow access to the authenticity verification service powered by Certilogo often display the CLG Code. It’s easy to find: it’s a 12-digit numeric string preceded by the acronym CLG, for example “CLG 000 000 000 000”.
