Terminal’s mobile readers work with iOS, Android and React Native SDKs and use Bluetooth Low Energy to connect to the SDKs on an Android/iOS device, these include: Stripe Reader M2 (US only), and BBPOS WisePad 3 (outside of the US).

• Make sure your reader is sufficiently charged. If a reader software update is needed prior to connecting to your application, 50% battery life is required. If no reader software update is needed, 10% battery life is required. You can check our latest reader software versions (WP3 here, M2 here) to confirm whether your mobile reader requires an update. See our technical documentation for details on how to update reader software.
• Make sure your application is set up as follows:
  • Your application uses iOS/Android SDK 3.0.0 and above
  • Connection is established via the connectReader method and not from Bluetooth Settings on your mobile device. Read more in our documentation documentation on card reader discovery and connection.
  • A `locationId` has been provided with your physical operating address during reader connection. For technical details on this implementation, please visit our documentation on card reader discovery and connection. For more details about terminal Locations, visit our reference on fleet management.
• If you are experiencing disconnects when the reader is powered off, battery is low, or when the reader is outside of bluetooth range, please review our docs here.
• Make sure your card reader is able to successfully install software updates. If required software updates fail to install, then the reader will fail to connect to the point-of-sale application. When installing software updates, leave the device powered on and in-range near your POS application.
  • If software updates fail repeatedly, then record the error message and contact support (link :https://support.stripe.com/email)
• Consider enabling auto-reconnection if not enabled already. It is enabled by default in SDK V4.
• If you use the Android SDK, check out USB connections.
  • USB-connected readers avoid Bluetooth interference and disconnection issues by using a wired connection to the reader.
  • Please email us if you are interested in USB connection with iPads.
• Factory reset the reader
  • For the BBPOS WisePad 3: you can attempt a reset of the device by inserting a pin into the small pin-hole right beneath the power button
  • For the Stripe Reader M2: you can reset the device by inserting a pin into the small pin-hole on the read of the reader
• If all of the above fail, please review our reader return steps.
