# Overview

Physically picking up and dropping off keys can be time-consuming when testing your application. To streamline development, Keycafe provides the ability to simulate key exchanges.

Keys can be virtually moved in and out of a sandbox location for testing purposes.\
Simulated exchanges:

* Are free and unlimited.
* Still trigger email and SMS notifications if those features are enabled in your account settings.

This allows you to test key exchange workflows without requiring physical interaction with a SmartBox.
