What is the maximum value for maxDistance for Apple Wallet Pass?

According to Wallet Developer Guide the pass geo-location radius depends on pass style.

Large radius (max. 1000m):

- Event ticket
- Boarding pass

Small radius (max. 100m):

- Coupon
- Store card
- Generic

But you have to be aware that these values can change.

In both cases, the exact relevance radius is an implementation detail and may change.

Moreover you won’t get notification everytime.

Boarding passes and event tickets almost always specify a relevant date, so they appear only on the valid date and not each time the user is near the location.
