Square Stand Intermittent Card Reader Detection Issue – Requires iPad Reinsert to Restore Functionality

Questions
1

Hello Square Support,

I am using Square Stand with my custom POS system (not Square’s own software) and integrating it with SquareMobilePaymentsSDK. I have encountered an issue where the Stand sometimes fails to recognize the card reader or tap-to-pay when I enter the payment screen.

:small_blue_diamond: Issue Description:

• Normally, the Square Stand functions correctly, and the card reader (tap or swipe) works as expected.

• However, occasionally, when I go to the payment screen, the white LED light on the Square Stand does not turn on, and the system does not detect the reader.

• The way to fix this is to physically remove the iPad from the Square Stand and reinsert it. Once reinserted, the white LED turns on, and everything works again.

:small_blue_diamond: Questions:

  1. Is this issue related to software (SDK ), or is it a hardware connection problem?

  2. If it is a software issue, where can I find relevant documentation or debugging information to diagnose it?

  3. Are there any specific API calls or error logs that I should check to determine why the Stand stops detecting the card reader?

  4. If it is a hardware issue, what are the recommended troubleshooting steps to ensure a stable connection between the iPad and Square Stand?

Thank you for your support!

If it’s a hardware issue have you looked at the connection of the iPad and Stand to make sure it’s clean?

As for SDK troubleshooting are you logging readers states when this happens? :slight_smile:
