QR menus and weak signal: what happens when 4G drops
Published
In many cafés, 4G is weak at the back of the room, downstairs, or on match nights when the whole neighbourhood is online. A QR menu has to hold up in those moments. Here is how to prepare your network, your menu and your team so a drop in signal does not turn into a problem.
Start the free trialWhat really happens when the signal fades
The network rarely cuts out all at once. Usually it just gets slow: the page takes ages to open, a photo will not load, a button seems to do nothing. The guest taps twice, loses patience, then raises a hand for the waiter.
The worst spots are well known: basement rooms, thick walls in old medina houses, beach terraces in summer, and every café on a big match night. If your venue fits one of these, assume the signal will weaken one day in the middle of service.
Offer guest Wi-Fi that actually works
The best fix is guest Wi-Fi that is well placed and easy to join. Put the router or a repeater in the middle of the room rather than in a cupboard at the back. Choose a password that is easy to type and display it clearly.
If you can, separate the guest network from the staff network, so the waiters' phones, the kitchen tablet and the printer do not slow down because twenty guests are watching videos. Many routers offer a 'guest' network: ask your internet provider how to turn it on.
Keep the menu light
A menu full of large photos and long videos takes longer to open on a weak network. Use reasonably sized photos, only for the dishes that need them, and keep descriptions short.
A clear menu, well sorted into categories, helps too: guests find what they want faster and order before the network acts up.
The staff network: a backup plan
If the router goes down, waiters can switch to 4G on their phones. For the kitchen or bar tablet, keep a charged phone that can share its connection. Try this hotspot once during a quiet hour so you know how long the switch takes.
Write your internet provider's support number next to the router, and teach at least two people on the team how to restart it properly.
The human backup plan
No technology replaces an attentive waiter. Keep a few paper menus or a chalkboard for the worst cases, and remind the team of the golden rule: a guest who cannot order on their phone never waits. The waiter takes the order by voice.
The same goes for older guests and anyone who prefers to talk to a person. The QR menu is there to help the team, not to replace it.
Before a busy night: a five-point check
Before a match night, a Ramadan evening or a summer Saturday, take five minutes. Open the menu on your phone over 4G at the back of the room. Join the guest Wi-Fi using the password on display. Check the kitchen tablet is receiving orders. Charge the backup phone. Remind the team of the backup plan.
If any step fails, you still have time to fix it before guests arrive.
With Tablilo
Tablilo was built with these situations in mind. The menu opens even offline after the first visit, and an order sent during a drop resends itself when the network comes back. Guests copy the Wi-Fi password in one tap from the menu.
Waiters can also key in an order on their phone for guests who prefer to order by voice, and the kitchen screen runs on any tablet. Try it in your own room during the free trial, at the back where 4G is weakest.
