# How to handle multiple distinct markers
Now that we have seen various possibilities of [AR.js](https://github.com/jeromeetienne/ar.js),
let's end with an last examples with multiple distinct markers. Those can be useful in various applications
e.g. a 'measure it' like below.
So we will have 3 markers, one with a preset, one with a custom pattern marker, and a barcode.
TODO to complete
- link to measure it example
- video of it
- what's the use
- e.g. you can see it in this [multiple independent markers example](https://jeromeetienne.github.io/AR.js/aframe/examples/multiple-independent-markers.html)
