What is a connected product?

A "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.

What use are connected products?

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.

What is a smart tag?

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”.

Where are smart tags located?

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.

Can I share the CLG Code on the smart tag of one of my products with friends who want to try it?

No, if you want to share the experience of using the authenticity verification service with your friends, show it directly by using your own smartphone, tablet or PC. Our AI algorithms are designed to identify anomalies in the use of the verification service and, therefore, the system’s reply also depends on who carries out the verification, meaning that your friends may receive a negative reply. Furthermore, it would represent a "misuse" of the platform under the Terms and Conditions of Service that you have accepted.

Can there be two products that have a smart tag with the same CLG Code?

No, every smart tag has a unique CLG Code linked to a specific product.
Counterfeiters may try to create copies or replicas of CLG Code to make their fakes look authentic, but they cannot trick the authenticity verification service powered by Certilogo which, during the verification phase, will never reply that it is "Authentic".

Is it possible to check the authenticity of a product sold online before purchase?

No, to be sure that the product is authentic it is necessary to have it with you.
Finding the Certilogo Code published online, or receiving a photograph from the seller, does not guarantee that the product is authentic. The only way to be sure that a product is authentic is to perform an authenticity check when you have it with you.
Several products sold online come with an active SOA - Certilogo’s Seal of Authentication.
The SOA is a digital twin of the smart tag showing the CLG Code that sellers can get from Certilogo and display in their online listings to prove that they are selling an authentic product. Buyers can scan the SOA they find in the online listing to check that the product is authentic. To make sure that the product shipped is the original one, we recommend that you scan the physical tag you find attached to the product once you receive it. If you wish to verify the authenticity of a product sold online before purchase and there’s no active SOA in the listing, do not worry: Certilogo will show you how to ask the seller to provide one.

What is the Certilogo "Fake Report"?

The Fake Report is a free document with which Certilogo confirms that your authenticity verification on a particular product produced a negative result. You can attach this document to any complaint that you decide to submit to whoever sold you the product, to the credit card company or to the payment service you used to make the purchase.

I am an online seller: how does the SOA work?

You can only apply for a SOA if you can prove that you physically possess a genuine product. To obtain it, you just need to perform the authenticity verification and follow the instructions that you are presented once you receive the reply "Authentic". We will ask you to list the platforms on which you intend to sell the product and upload clear, close-up photos of your product and the smart tag with the CLG Code. We will send you the SOA in PDF format by email within 24 hours and you can publish it on your advertisement or site.

I am an online seller: do I have to use any special precautions regarding the SOA?

Yes, as indicated in the Terms and Conditions of the service, it is important never to post a photo of the physical smart tag on your site or advertisement. The reason is that scanning or entering the CLG Code initiates an authentication process that can only be completed by whoever physically possesses the product. If you make the CLG Code public and various users initiate authentication without physically having the product, the system reports an anomaly and your customers will not be able to check the authenticity of the product you are trying to sell.
If, on the other hand, you create and publish the SOA, you give all potential buyers the opportunity to check the authenticity of the product before purchasing and you will make your original products more attractive.

I am an online buyer - how does the SOA work?

If you are considering purchasing a product offered online and equipped with a smart tag with a CLG Code, the seller may have published a SOA on their site or advertisement. In such cases, you just need to scan the QR code on the SOA using a smartphone or merely type the digits on the CLG Code (eg. CLG 000 000 000 000) on and follow the instructions.
The reply “Authentic” means that the online seller actually has a genuine product and you can buy it with peace of mind. Upon receiving the product, scan the accompanying physical smart tag, so you can confirm that the seller has shipped the correct product.
The reply “False”, on the other hand, means that the online seller has fraudulently copied the SOA of another legitimate online seller, naively believing that they can circumvent our anti-counterfeiting system.
