See your reader in action: 

Turn your card reader on and off

To turn on your Cheddar Up card reader, press and release the power button. The status light turns on to indicate power. The reader waits for a Bluetooth connection for five minutes before turning off.

When the reader is connected to a device, its status light shines steady blue. If the reader is inactive for more than 30 seconds, it enters standby mode to conserve power, and the status light begins flashing at five-second intervals. The reader stays connected to your iOS or Android device while in standby and automatically exits standby mode when you resume activity.

The reader automatically turns off after 10 hours of inactivity. To turn the reader off manually, press and hold the power button until the status light goes out. You don’t need to turn off the reader to conserve power.

Card reader battery life

Upon arrival, your card reader should be fully charged. To charge the Cheddar Up card reader, use the included micro-USB cable. The USB port does not work for connecting the reader to a mobile device—it’s only for charging.

With typical usage, you only need to charge the reader once per day. To be more specific, a single charge of the Cheddar Up card reader battery can support approximately 800 EMV transactions, 5,000 magnetic card swipe transactions, or 1,000 EMV contactless transactions.

Accept your first point-of-sale payment

Go here, for a step-by-step guide on how to accept your first point-of-sale payment using your new Cheddar Up card reader. 

Enable location services

In order to accept point-of-sale payments, Cheddar Up requires you to enable "location services" on your mobile device in an effort to protect organizers and payers. Upon your first point-of-sale checkout, you'll be prompted to enable location services. If you accidentally decline this request, take the following steps to enable location services.

On an iOS device:

  1. Tap the Settings application.
  2. Tap Privacy.
  3. Tap Location Services.
  4. Toggle the switch to On.
  5. Scroll down to the Cheddar up app icon.
  6. Select "While Using the App" or "Always".

On an Android device:
  1. Tap the Settings menu.
  2. Tap Location.
  3. At the top, turn Use location on or off.

Common Questions

What do I do if my reader will not connect?
If your reader will not connect, there's likely a valid (and fixable!) reason for it. Check out this guide outlining the Top 5 Reasons Why Your Reader Will Not Connect. In addition, the most common reasons why a reader will not connect are because Bluetooth is not toggled on within device settings, or because the reader was paired within device settings instead of within the Cheddar Up POS payment flow. The guide mentioned above will walk you through all possibilities and help you troubleshoot.
