V1 Register forced customer display disconnected error

Caubetiep — Fri, 27 Feb 2026 18:13:33 GMT

square just forced incompatibility between V1 register and customer display. Everything fine, no signs or gradual glitches, suddenly mid day customer display stopped working with “Customer Display Disconnected” error. No longer can take payments. Soft reset, hard reset, reconnect power cable, reseated/redocked display. No avail. Calling support was told it’s because v1 is not supported and need to buy a new device. So much for being able to continue using the v1 and take payments as mentioned on their end of life announcement article.

toast and clover had been trying to poach me but I hadn’t entertained it. Now I’m sure as hell changing from square. Adding 2 more locations this year and 2 next year. Still we are nobodies but Square lost a customer for sure. shady practices and laying off half of their block staff. My first and last post. Bye

That is interesting. I haven't used my Terminals as customer-facing displays. I tried it for a little bit, but I just thought it added too many complications to the super-fast checkout experience. I have 6 terminals, and 2 are still the older model.

@TheRealChipA do you use the terminals as a customer-facing display?

@VanKalkerFarms I do, but I don't think that connected terminal is @Caubetiep's issue. They mentioned Register and, as far as I know, while V1 Registers will only continue working if no more software updates are applied after the last supported update. Once any update is done (even via factory reset), then the V1 Registers are paperweight. Square warned Register users about that and suggested that everyone turn of automatic updates. If that didn't happen, there is no going back of which I'm aware.

I totally didn't read that right. Thanks for getting it right.

That's one reason I don't like Square terminology of Register or terminal etc. A lot of people just call it their Square Register when it is an iPad or whatever. I guess I was just not thinking clear after Isabelle's message.

I wish I could say that has NEVER happened to me, Bob. And I agree with you re: Square terminology sometimes. But they are by no means alone in that arena. (And, yup, it has been an oddly distracting week. Hopefully that gets better again soon.)
