What is a "connected product"?

It is a physical product made interactive by means of a so-called "smart tag". The smart tag is a physical medium, for example a label, a sticker, a card or a tag, which contains a "digital enabler", i.e. an NFC chip, a QR code or some other technology that can be read by an electronic device, typically a smartphone, in order to trigger a specific action, such as a connection to a website or application.
