PassConstraints

  • Pass constraints can be set to control screenshot eligibility and NFC behavior.

  • screenshotEligibility determines if screenshots of the pass are allowed on Android devices, with options for eligible or ineligible.

  • nfcConstraint allows restrictions on NFC interactions when the pass is open, such as blocking payments or closed-loop transit cards.

  • The default behavior for screenshots is eligible, and there are no NFC constraints by default.

Container for any constraints that may be placed on passes.
