Hi @BlushBrows,

 

Thanks for getting in touch and sorry to hear about the trouble you've had connecting your reader.

 

The error you're seeing here about "Developer Options" is actually due to a setting on your mobile device rather than the Square reader itself. Square readers require a secure operating environment in order to process sensitive card data, which means the "Developer Options" on your Android device should be turned off.

 

You can generally find this setting on your Android Device under "Settings" then "Developer Options" (usually located towards the bottom of your settings) - make sure you flick Developer Options off. Once you've done this, you should be able to pair the reader successfully via the Square POS app.

 

Please let me know if this helps or if you need any further assistance!

My reader was fine and accepting payments and then all of a sudden stopped working and is giving me the "developer options" message. I have turned it off in settings but I still can not pair my reader.

Hey @Trishhull,

 

Sorry to hear you're having trouble getting your reader working. Can you let me know what make and model of mobile device you're using?

Why cant I use the card reader when my phone has developer mode enabled. Developer mode is not a security issue so developer mode should not have any effect on the APP or the Card Reader. Due to my disability I require developer mode to be enabled to use specific functions on my phone but the Square reader will not allow this so every time I want to take a payment I have to turn the developer mode off then restart my phone then when I have finished I have to turn it back on again to continue using my phone as normal. This is crazy no other payment solution like iZettle or Worldpay have this issue so why has your Reader. I'ts beginning to drive me nuts can you do an update to fix this I don't want to but I will need to go back to the Worldpay card reader system instead if this is not fixed soon.

Hey @Daz1847,

 

Thanks for getting in touch and sharing your experience using Square.

 

To the best of my knowledge, one of the key reasons Square has stricter security requirements than some other card readers is due to differing PCI compliance standards for devices that use "PIN on Glass" tech - ie a PIN is being entered on a touchscreen via software, rather than buttons on a separate device.

 

Because having developer options enabled allows for much more control and customization of how Android operates, it does unfortunately mean we can't accept card payments in this environment.

 

With this said, it's our goal to make our products as accessible as possible for as many people as possible. If you'd like to send me a PM with more info about how you use Square and your mobile device in general, I can share your feedback with our product development teams and see if we have any other advice to give.

Have a Samsung Note 9 and had developer options enabled.

I have disabled it but is now saying not supported.

I have cleared cache for the app and reset the square, but still no luck

Hey @JaGuR,

 

It sounds like there is a setting or app on the device that is preventing Square's reader from forming a secure connection. It's a little difficult for us to pinpoint what that can be without the device at hand - do you recall installing any new apps, updates or turning on new features if the device was previously working? Do you have any apps that can be used for screen recording/sharing or that make use of screen overlays?

 

It might be a good idea to try calling our technical support team for further assistance on 1800 760 137.

 

If the device previously worked with Square, as a last resort you could also try restoring the phone to it's factory settings, which should restore the phone to a state whereby no apps or settings are conflicting with our ability to securely process payments.
