# Filters Interface

The **Filters Interface** in the CloudBox allows you to control which tag passings are processed during a timing session. By applying filters, you can ensure that only relevant bib numbers or chip mappings are included, making your timing data cleaner and easier to manage.

The interface is divided into two main sections:

* **Bib Filters**: Lets you define ranges or specific bib numbers to include.
* **Cross-Reference Table**: Allows you to map raw chip EPCs directly to bib numbers, creating a structured link between chip IDs and participants.

These tools help race organizers tailor the data flow to match the event’s requirements, whether by filtering out irrelevant tags or linking EPCs to known bib numbers.

## Where to Learn More

This article introduces the Filters Interface, but the details of how to use **Bib Filters** and the **Cross-Reference Table** are covered in the **ADVANCED OPERATIONS** section. There, you’ll find step-by-step explanations and examples on how to:

* Configure and manage bib ranges.
* Load and enable cross-reference tables.
* Optimize your filters for real-world race conditions.
