Scanning

Before starting a transaction, scan for available readers with DeviceScanService.

let deviceService = DeviceScanService()

deviceService.scan { (result: DeviceResult) in
    switch result {
    case let .success(devices, isScanning):
        for device in devices {
            // Select and retain the device for the transaction.
        }
    case let .error(error, isScanning):
        // Handle the scan error.
    }
}

Stop scanning when it is no longer needed:

deviceService.stopScanning()

After selecting a device from the scan results, provide it when the transaction flow requests a reader. Apple Tap to Pay is returned as another available device when the device supports it and its installer was registered in the SDK configuration.
