USB & OTG adapters

If you're using a USB-A reader on a modern USB-C phone, the adapter quality matters more than people expect.

USB-A → USB-C adapter

A short, decent-quality USB-A to USB-C adapter for plugging legacy USB-A readers into modern Android phones. Stick to known-good brands — the cheapest no-name adapters are a common cause of failed reads.

How we verify a reader

A short, repeatable process so a "verified" badge actually means something.

  1. 1

    Plug into multiple Android devices via USB-OTG (USB-C and USB-A test rigs).

  2. 2

    Confirm Android USB-permission dialog triggers without manual driver installs.

  3. 3

    Download a real driver card and ingest the file through the HGV Time Pilot pipeline.

  4. 4

    Verify the resulting timeline matches the card's known activity.

Pro tips

  • Use a high-quality USB-A → USB-C adapter if your phone doesn't have a USB-A port. Cheap adapters are the most common reason a verified reader stops working.
  • Avoid ultra-cheap, unbranded readers. Many appear to work (LED lights up) but never communicate with apps.
  • If your reader isn't on this list, it doesn't mean it won't work — but you're on your own. Tell us about it and we'll consider testing it.
