## Declaration

```data
object PassFields.SecondaryFields
```

## Mentioned in

Creating an airline boarding pass using semantic tags Creating a poster event pass using semantic tags Supporting semantic tags in Wallet passes

## Discussion

Discussion Use this field to provide information that people might not need every time they use the pass, for example, the flight number on a boarding pass, or a coupon expiration date. Depending on the type of pass, you can use the secondary and auxiliary fields interchangeably. Coupons, store cards, and generic passes with a square barcode can have a combined total of up to four secondary and auxiliary fields.
