Why does my tap & chip reader keep unpairing at my POS?

Retail & Point of Sale

Topic summary

Shopify’s tap & chip card reader experiences persistent Bluetooth disconnection issues, requiring frequent re-pairing that disrupts checkout operations. The problem affects multiple users despite hardware replacements (readers and iPads), software updates, and router changes.

Key Issues:

  • Readers disconnect 1-2+ times daily, even after iOS 12.4 and Shopify app 5.33.1 updates that initially seemed promising
  • Devices enter sleep mode and won’t wake, requiring full deletion from Bluetooth settings and iPad restart
  • Physical design flaw: dock must be dismantled to access power button
  • Some units completely fail with flashing red/blue lights and won’t revive

Workarounds Mentioned:

  • Daily power cycling of all equipment during store opening
  • Using reset button (pinhole, not blue button) for locked devices
  • Switching to older chip/swipe reader (white model with base) for better reliability
  • Some merchants purchasing Square Terminal as backup

Business Impact:

  • Customer frustration and abandoned transactions during checkout delays
  • One user logged 600+ troubleshooting hours
  • Multiple replacement units show identical problems

Status: Unresolved. Users report Shopify support treats each case as isolated rather than acknowledging systemic issues. Requests for wired connection option or return of older reader models remain unaddressed.

FWIW, we have one of our companies using Lightspeed Retail. Similar setup, iPads, Bluetooth barcode scanners, Bluetooth receipt printers, but with Ethernet-connected payment terminals. Our operators report disconnects with the Bluetooth equipment on a daily basis. Power cycling them and repairing always is the fix. Inconvenient when a customer is standing there (with a potential line behind them) but it works.

The Shopify POS retail kit is aesthetically pleasing. Sturdy, can bolt into the countertop, and clean. But the Bluetooth payment terminal was poorly designed and engineered from a usability standpoint. If power-cycling the device requires the front plate be removed, then that’s another inconvenience when a customer is sitting there waiting to be rung up. We are testing out Shopify POS with this new black retail kit. And have run into many of the issues echoed on this thread. I think frankly it’s the nature of the beast. Bluetooth devices can go to sleep, can lose their connection pairing, and can’t remain powered on persistently 24x7 and maintain proper connectivity.

If we are going to implement Shopify POS for our other company I am going to recommend we power off all devices at store closing and power them all back on for store opening. And that any Shopify POS or iOS updates be thoroughly tested on a retail kit before upgrading our production devices. There are too many cases where either an update fixes or an update breaks the wireless connectivity between the iPad and the devices.
