QR✓OK is installed at venues by POS partners: Poster dealers, iiko integrators, R-Keeper dealers. Nothing is installed on the register — the register prints the code itself. Here are the installation guides for each POS.
What the guest sees — the demo. The venue needs its own UzQR code from its bank: how to get UzQR.
QR✓OK is in a pilot now: everything is free for venues, and no invoices are issued. On top of that, each point pays nothing for the month in which its first pre-bill is printed and for the whole of the next month. We give the venue at least 30 days' notice before the paid period starts. Current plans are on the Pricing page, terms in the Public Offer.
