# Tracking protocol The surveys we have sent out to our followers in emerging markets paint a clear picture: customers do not trust online marketplaces. A vendor who wants to prove his reliability opens up Logyq’s app and starts registering info about one of his products; Logyq then sends the info on the Cardano blockchain and generates a QR code for each tracked item. A customer scans the QR code once the item arrives and consults all the relevant information about it. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://logyq-protocol.gitbook.io/whitepaper/use-cases/tracking-protocol.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
