Pairing the Card Reader with Bluetooth on iOS / Android to Start a Transaction
In order to be used for processing a transaction, the card reader must be:
  • Turned on
  • Paired with your iOS / Android device via Bluetooth
  • Not in Sleep mode
To pair the card reader:
  1. Before starting a transaction, make sure the card reader is paired with your device.
  2. Turn on the reader by pressing the power button.
  3. Activate the card reader from Sleep mode by pressing any key.
  4. On iOS devices: Make sure the Bluetooth connection is active, which is indicated by the black Bluetooth symbol appearing next to the battery symbol on the device screen. The connection is usually automatic after you wake the reader from sleep mode. You can also manually activate the Bluetooth connection by tapping to select the card reader in your iOS device's Bluetooth settings, after the reader has left the sleep mode.

Restarting the Card Reader

  3. Remove the card reader from the list of connected Bluetooth devices on your phone.
  4. Verify that the card reader is turned on and not in sleep mode (see above).
  5. Start a transaction.
Managing Tampered Card Readers
The Miura card reader has a tamper detection system to detect unauthorized manipulation of the reader hardware. This system can, for example, detect if the device has been tampered with so that eavesdropping can be done on the PIN entered by the customer. The detection system is triggered when a person tries to open the card reader case or when the reader is dropped hard onto the floor. When the tamper detection system is triggered, the Miura card reader screen will cease to function and only display the
prompt. If this situation occurs, contact your hardware provider to get the card reader replaced.
