# PassFields.AuxiliaryFields

An object that represents the fields that display additional information on the front of a pass.

```
object PassFields.AuxiliaryFields
```

## Discussion

Use this field to provide information that people might not need every time they use the pass.

Depending on the type of pass, you can interchange the auxiliary and secondary fields. Coupons, store cards, and generic passes with a square barcode can have a combined total of up to four secondary and auxiliary fields.
