# events

A stream of events you receive indicating the activities of the payment card reader.

```
final let events: AsyncStream<PaymentCardReader.Event>
```

## Discussion

When calling [`prepare(using:)`](/documentation/ProximityReader/PaymentCardReader/prepare(using:)), the [`PaymentCardReader.Event.updateProgress(_:)`](/documentation/ProximityReader/PaymentCardReader/Event/updateProgress(_:)) event will indicate the completion percentage of the configuration.
When reading cards with [`PaymentCardReaderSession`](/documentation/ProximityReader/PaymentCardReaderSession), the raised events will indicate the current state of the card-reading process.
