# Data Base

The DEXPIRY database contains detailed information about each individual product, represented by a unique Token ID. Access to this information depends on the authorization level of the DEXPIRY application user.

While the *Administrator* and *Regulator* authorization levels have access to the entire database content, the *Token Issuer* and *Basic User* have access only to the tokens they have created (*mint*) or received (*claim*).

The entry into the DEXPIRY database is made by *Token Issuers*, after the sold product has been assigned a unique Token ID when creating the DEXPIRY token.

The information about the sold product entered in this way becomes available to DEXPIRY application users depending on the assigned authorization level, and its purpose is to enable easier monitoring and exercise of warranty rights for a particular product.

**Information about each product stored in the database:**

* Unique Token ID
* DEXPIRY number - Product category and model
* Invoice number
* Product serial number
* Warranty issuer information
* Warranty status (active, inactive, used)
* Link to access the digital version of the warranty card for the product in question (covered defects/conditions)
