Set up Stripe Reader M2
Stripe Reader M2 is a small, robust reader for use with mobile applications. It uses Bluetooth Low Energy (LE) to connect to the Stripe Terminal SDK on a mobile device.
This reader requires the Stripe Terminal SDK 2.1.0 (or later) for iOS or Android. If you’re using the 1.x version of the SDK, update to the latest version. To view the reader’s parts and features, see the Stripe Reader M2 product sheet.
Turn the reader on and off
Turn on the Stripe Reader M2 by pressing and releasing the power button. The status LEDs turn on 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.
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 USB cable. The USB port is only for charging and doesn’t work for connecting the reader to a device.
Check the battery status
When the Stripe Reader M2 is on, you can press and release the power button once to check the battery level. The LEDs on top of the reader show the current status.
