iDynamo Setup

The iDynamo is a plug & play device that connects to the iPad’s charging port. It does not work with Apple Pay or NFC technology. If you are not using a ShopKeep stand, you must set up the iDynamo with one of the included adapter sleeves.

  1. Find the adapter sleeve labeled with the name of your iPad model.

    If your setup does not require an adapter sleeve, skip to step 4.

  2. Align the prongs on the sleeve with holes on the iDynamo.
  3. Push the pieces together until you hear a click.
  4. Plug the iDynamo into the iPad.

    The iDynamo is now ready to process swiped credit cards in The Retail POS (S-Series) app. Before accepting credit cards, your Lightspeed Retail account must be boarded for credit card processing. Learn how to set up credit card processing here.

  5. (Optional) Set the iPad up in a stand or enclosure.
  6. (Optional) To charge the iPad, plug a micro USB cable into the port on the back of the reader. Connect the other end of the cable to the iPad’s charging adapter.

    Charge the iPad only when needed. Leaving the micro USB cable attached all day can cause damage to the charging port on the reader.
