# performTransaction(using:options:)

Prompts the user for authorization and then activates a credential for card emulation.

## Declaration

```swift

```

## Parameters

- `credential`: The credential to activate and transition into card emulation state.
- `options`: The options to activate the credential with, defaults to none.

## Discussion

Discussion If this call succeeds, the session state trasitions to CredentialSession.State.cardEmulation(credential:). Card emulation ends after 60 seconds, at which point the the event stream publishes a CredentialSession.Event.cardEmulationTimeout event. If you complete your transaction before the timeout, call endCardEmulation() to exit card emulation mode. The caller needs to invoke invalidate() after completing each transaction. important: Calling this method may generate a billable event to the credential provider.
