Frequently Asked Questions

Here you will find answers to the most important questions about the Tokentags.

What do I need to use tokentags?

The tokentag can be easily read out with any NFC-enabled smartphone. A simple tap is enough to call up the associated digital certificate on tokentagged.com. For verifying the signature or writing the tokentag during the minting process, only an Android smartphone with a Chrome browser or a smartphone with the Tokentagged app installed is required.

How can I, as an artist, benefit from the Tokentag certificate?

The Tokentag replaces the traditional paper certificate with a digital, tamper-proof certificate of authenticity on the blockchain. As an artist, you benefit in multiple ways: You receive automatic royalties on every future resale through smart contracts. Your works become tradable on global digital marketplaces. The complete history of each artwork – from creation to every change of ownership – is immutably documented. Additionally, the Tokentag system protects your works against counterfeits and simplifies authenticity verification for buyers and sellers alike.

How can I, as a manufacturer, benefit from the Tokentag certificate?

As a manufacturer, the Tokentag gives your customers a tamper-proof digital certificate of authenticity – no more paper certificates that can be forged or lost. Your customers can verify the authenticity of your products in seconds with a simple smartphone scan. Additionally, you can participate in every resale through automated royalties. Customers also benefit by being able to unequivocally prove the ownership of your (for example, limited) products.

What advantages does a digital certificate with Tokentags offer over a traditional paper certificate?

The digital certificate with Tokentags offers significant advantages over traditional paper certificates:

Tamper-proof: Unlike paper certificates, the digital certificate on the blockchain cannot be forged, altered, or destroyed. The authenticity is cryptographically guaranteed.
Complete provenance: Every change of ownership is automatically and immutably recorded. Buyers and sellers can trace the entire history of an artwork at any time.
Automatic royalties: Smart contracts allow artists to automatically participate in every future resale – something no paper certificate can do.
Global digital marketplaces: Certified works become tradable on international digital marketplaces, opening entirely new sales channels.
Always available: The certificate cannot be lost, misplaced, or damaged – it is permanently stored on the blockchain.

In summary, the Tokentag transforms a traditional paper certificate into a living digital document that actively creates added value for artists, collectors, and manufacturers.

How is the connection between tokentag and NFT established, and why can't the NFT be copied?

The tokentag and the associated NFT work through a secure and unique technology. Each tokentag generates a private key, from which a public key is then generated. This public key serves as the token ID. Since the private key is secret and known only to the tokentag, no one else can produce an identical tokentag with the same token ID. This makes each tokentag unique and uncopyable. When minting an NFT, a special contract address is set along with the tokentag's token ID and stored on the tokentag. This contract address cannot be changed later, making the tokentag and the NFT inseparably linked. This connection ensures that the authenticity and originality of the NFT are always traceable and secured.

How difficult is it to copy or counterfeit tokentags?

The security of our tokentags is based on the use of highly secure microchips that have already proven themselves in critical security areas, such as bank cards and authentication systems. A crucial aspect of their security is the secret key generated within the tokentag. This key is stored exclusively in the tokentag itself and never leaves it, meaning it is inaccessible to anyone - not even us as the manufacturer. This makes counterfeiting a tokentag practically impossible, ensuring unprecedented security.
