Stripe Reader M2 Guide

Learn to use the Stripe Reader M2 BT mobile card reader with XTrulink.

The Stripe Reader M2 BT is a handheld reader for use with mobile applications. It uses Bluetooth Low Energy (LE) to connect to the Stripe Terminal SDK on a mobile device.


Stripe readers aren’t liquid-proof and we recommend that users make appropriate efforts to make sure their devices remain dry. If your device has experienced liquid ingress, we recommend that you stop using the device and let it dry thoroughly before attempting to re-use or charge the device. If your device doesn’t properly operate or charge properly after drying, you need to replace it.

Turn the reader on and off

Turn on the Stripe Reader M2 by pressing and releasing the power button. The status LEDs turn on for 2 seconds and the reader beeps twice. The reader waits for a Bluetooth connection for five minutes before turning off.

When the reader connects to a device running your app, the status LEDs on top of the reader flash four times. After connecting, the first status light begins flashing at five second intervals. The reader stays connected to your iOS or Android device while in standby mode and automatically exits standby mode when you resume activity.

When connected, the reader automatically turns off after 10 hours of inactivity. You can turn off the reader manually by pressing and holding the power button for four seconds. You don’t need to turn off the reader to conserve power. When the reader turns off, the four LEDs light up and then turn off one by one to indicate it has turned off.


With typical usage, you only need to charge the reader fully once per day.

Charge the reader

To charge the Stripe Reader M2, use the included cable or a USB 2.0 cable.

Check the battery status
