How Many QR Codes Does Your Restaurant Actually Need?

Per table, per area or one code: how the three approaches compare

A code on every table is the most common setup. A guest sits down, sees the code within arm's reach and scans it without asking anyone. The trade-off is volume: more codes to print, wipe clean and replace, and more chances for one to go missing.

A code per area means one code for each zone, such as a row of window tables, a lounge corner or a private room. It is less to maintain, but it only works if the code is visible and reachable from every seat in that zone. If guests have to stand up and walk to it, some will simply wave for a waiter instead.

A single code at the entrance or on a stand suits a small café with a handful of tables or counter service. In a full restaurant it creates a queue at the door, and guests who scanned once often cannot find it again when they want to reorder.

One question to put to any provider is whether an order can be tied to a specific table or zone, and how that is set up. That depends on the platform, so confirm it before you print anything.

Bars, terraces and takeaway counters need their own thinking

Takeaway is the easiest to get wrong. Put a code at the counter where people wait, another on the door or window for passers-by, and consider a small sticker or flyer that goes out with each order so the next one is a scan away. Guests who never sit down still need a code within view.

Bar seating has no table to anchor a code. Place codes along the bar top every few stools so nobody has to lean across a neighbour, and keep one at the point where staff hand over drinks.

A terrace adds weather. Sun glare, wind and rain all attack a printed code, so use matte finishes, weighted holders or fixed stands, and check that a phone can actually scan the code in bright daylight. If reception is weak at the edge of the terrace, consider posting your Wi-Fi details next to the code.

Choosing materials, size and placement that survive a real service

Tables get wiped many times a day, so paper alone rarely lasts. Laminated cards, acrylic stands, or a code printed directly onto a hard-wearing surface all hold up better. Prefer matte over glossy, because gloss reflects light and makes scanning harder.

Size and contrast matter more than looks. Print the code large enough to scan comfortably from a seated position, leave a clear blank border around it, and keep it dark on light. Avoid stretching it, tinting it in low-contrast colours or covering part of it with a logo unless you have tested the result.

For placement, think about where a guest's eyes and hands go: the table centre, next to the table number, or on a stand that also holds condiments. Avoid the table edge where plates land, and avoid spots under candles or bottles. Add a short line such as "Scan to see the menu and order", ideally in the languages your guests speak.

Before printing the full set, test one code on several phones at the actual table in the actual lighting.

What to do when a code is damaged, lost or needs reprinting

Damaged codes are inevitable: scratches, sticky residue, faded ink, a card that walks off with a guest. Make checking them part of the opening routine, with one staff member scanning each table before service. A code that does not scan is worse than no code, because the guest is stuck and someone has to notice.

Keep a small stack of spare printed codes behind the bar, and keep the original print file somewhere safe. Ask your provider how you can get a code again if you lose the file, so a replacement takes minutes rather than a new design job.

Ask too whether a code needs reprinting when the menu changes. In general, a code points to a web address rather than to a fixed document, so changing the contents of the menu does not require new codes, but confirm this with your provider. With ChargeM3, adding, editing or removing items takes minutes, and there are no app-store resubmits to wait on.

Have a fallback for the moment a code fails mid-service. ChargeM3 includes a mobile app for taking orders on the go, so a waiter can take that table's order from a phone while you replace the code.

A simple way to work out your number

Count the tables, then add the bar sections, the terrace, the takeaway counter and the entrance. Add a few spares for replacements. That total is your print run, and it is usually smaller than owners fear.

If you are unsure, pilot one section first, watch how guests behave for a week and adjust before printing for the whole room.

ChargeM3 is a single plan at €60 per month before VAT, with no installation fee and a 30-day free trial. It includes unlimited connected workstations, staff training and guidance on setting up your product catalog, so the team that will live with the codes is prepared before the first guest scans one.
