Why are my card payments failing with Tap & Chip reader?

When using the Tap & Chip reader, my card payments are failing to process.

  • This is the 1st time using it
  • Under manage hardware
    • Shopify show connected
    • Bluetooth is enabled
    • WIFI / Internet connected
  • I am using an Android Phone
  • When I go to checkout it says Tap or Insert card

is there anything that I’m missing?
