# QR Codes

A QR code is a machine-readable code that encodes data—such as a URL, text, or contact information—so it can be quickly scanned by a camera or reader. This provides a very quick way to generate a QR code formation.

| Content          | Text    | The encoded text message. Typically a URL                                                                                                                                                 |
| Correction Level |         | The amount of redundant data built into a QR code that allows it to be correctly read even if part of the code is missing or damaged. Particularly useful if missing drones is a concern. |
| Invert           | Yes/No  | if selected, where the usual dark modules are light and the usual light background is dark is inverted.                                                                                   |
| Step Size        | Decimal | The distance between points in the QR code                                                                                                                                                |
| Slot count       |         | The number of points required to create the QR code                                                                                                                                       |
