AI Thread Summary
The discussion revolves around implementing a system to print unique QR codes on till receipts for transactions exceeding a specified amount. The QR codes will be generated by a third-party server, which will recognize the codes when scanned, allowing for further actions based on the transaction data. Key considerations include the feasibility of this setup without direct integration with the POS system, the necessity for network connectivity for the POS, and recommendations for a suitable Wi-Fi enabled printer model. The inquiry seeks insights into the technical requirements and potential solutions for this QR code printing functionality.

Hi guys,

Does anybody here have an understanding of POS (point-of-sale) technology. I am looking for a way to print a QR-Code onto a till receipt if the dollar spend is over a set amount.
The QR-Code information to be printed would be pulled from a 3rd party server. Every till receipt that is printed with a QR-Code would have its own unique QR-Code on it.
The QR-Code that is printed can be scanned by a QR-Code reader and be recognised by the backend of the server that created that QR-Code.
So basically it sends the till information to the server and the server sends back the printed information with a QR-Code.This QR-Code is scanned and is recognised by server and performs some other action.
Is this possible without POS integration?
Would I be correct in presuming the POS will have to be networked?
What make/model of printer would you suggest? (wifi enabled)

Can anybody shed some light on this for me.

Thanks in advance.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
