Plan now, test in November and freeze changes in December. Count every device that will use the network on your busiest night, not just guests. Put card terminals and tills on their own network with a 4G or 5G backup, and check they fail over. Give seasonal staff their own till logins. Agree who to call on a Saturday night, and keep a card terminal with its own SIM in reserve. Christmas is eight weeks away: there's time, but not much.
Why is Christmas different for a venue network?
Most venue networks are built for an ordinary Saturday. Christmas stacks several busy Saturdays together, adds work parties midweek, and often adds places the network doesn't normally reach, such as a heated terrace, a marquee or a temporary bar in a function room.
Card spending shows the shape of it. Barclays' data for December 2025 showed spending in bars, pubs and clubs up 1.9% on the year, with the biggest spikes on Saturday 13 and Saturday 20 December (Barclays, reported January 2026). In 2026, the equivalent Saturdays are 12 and 19 December. Those are the nights your network can't fail.
Three other things change at Christmas:
- More staff you don't know well. Seasonal staff need till logins, handheld terminals and sometimes a staff WiFi password.
- More pre-paid bookings. Party deposits and pre-orders run through your booking system, so an outage costs you revenue before the night itself.
- Less room for fixes. Engineers, suppliers and your own managers are busy. Anything you change in December is harder to put right.
What uses your network on a busy night?
Guests' phones are the obvious load, but they're not the most important. Start with a list of everything connected and rank it. This is the order we'd protect it in.
| Priority | What | Why it matters | What to check |
|---|---|---|---|
| 1 | Card terminals and tills | No payments, no revenue | Own network, 4G or 5G backup, offline mode tested |
| 2 | Booking, ticketing and door scanning | Guests can't get in or find their table | Works if the main line fails |
| 3 | Kitchen and bar order printers or screens | Orders go missing | Fixed addresses, not guest WiFi |
| 4 | CCTV and door entry | Safety and licence conditions | Recording continues through an internet outage |
| 5 | Staff devices and phones | Managers need to communicate | Staff network separate from guests |
| 6 | Guest WiFi | Reviews, sign-ups, social posts | Enough capacity, speed limits per device |
If guest WiFi slows down on a busy night, people grumble. If card terminals slow down, the queue at the bar grows and people leave. Design for that order.
Separate the networks. Card terminals, tills and payment systems belong on their own network segment, away from guest WiFi and CCTV. That's good security, and it reduces how much of your network is in scope for PCI DSS, the card industry's security standard. Our leisure guide chapter on payments and PCI DSS covers this in more detail.
Limit guest devices. Set a per-device speed limit on guest WiFi so that one person streaming video can't slow everyone down, and block the heaviest traffic (large downloads, peer-to-peer) if your access points support it.
How do you keep card payments working if the internet drops?
Most modern card terminals connect over WiFi or your wired network. If your internet line fails, they stop working unless something else takes over.
A 4G or 5G backup on the router. A backup mobile connection that switches over automatically keeps terminals, tills and booking running while the fixed line is down. Test it by unplugging the main line on a quiet afternoon, and check that payments actually go through, not just that the router shows a mobile signal.
Terminals with their own SIM. Keep at least one terminal with its own mobile SIM for the bar or front desk. If the whole network fails, that terminal still takes payments. Check which mobile network it uses, and that the signal is good in the spot you'll use it.
Know your offline mode. Many terminals can store some transactions offline and send them later, up to a limit your payment provider sets. Ask your provider now what yours does, what the limit is and who carries the risk if a stored payment is declined.
Contactless limits haven't moved much. The FCA removed the regulatory £100 cap on single contactless payments on 19 March 2026, letting banks set their own limits. The major UK banks said they would keep £100 for now (FS Tech, March 2026). For a group bill over that, customers will still insert their card or use their phone's wallet, so terminals need to handle chip and PIN smoothly.
What should you test in November?
November is the month to find problems, while you still have time to fix them. Work through this list.
- Walk every space you'll use, including terraces and function rooms, with a phone showing WiFi signal. Note dead spots where terminals or handhelds will be used.
- Test the backup. Unplug the main line during a quiet trading period. Take a real card payment on each type of terminal. Check the booking system and door scanners.
- Check the power. Put the router, switches and backup unit on a small UPS (battery backup) so a tripped breaker in the kitchen doesn't take payments down.
- Set up seasonal staff properly. Each person gets their own till login and handheld login. No shared codes. Write down who they are, so they can be removed in January.
- Change the staff WiFi password if it's been shared with people who've left, and don't give it to temporary staff who only need the tills.
- Update and restart. Apply any pending updates to routers, access points and terminals in November, not December, and check everything comes back.
- Write a one-page "if it breaks" card for managers: who to call, the backup terminal's location and how to take payments manually if you must.
Then freeze. From the first week of December, no network changes, new systems or firmware updates unless something is broken.
Worked example: a 400-capacity venue with a function suite
Example (an illustration, not a real client): a Glasgow venue with a main bar and a 150-guest function suite is running work parties from late November to 23 December.
In October, the manager lists everything on the network: 6 card terminals, 3 tills, 2 kitchen printers, a door scanner, 12 cameras, 8 staff phones and guest WiFi. The function suite has one WiFi access point and two terminals that drop out when the room is full.
In November, an extra access point goes into the function suite, on the same managed system as the rest, with guest WiFi limited per device. Terminals and tills move to their own network. The router gets a 4G backup and a UPS. On a quiet Tuesday, the main line is unplugged: payments work, but the door scanner doesn't, because it was plugged into a guest port. That's fixed in ten minutes. In December, one terminal with its own SIM sits behind the main bar, just in case.
Nothing about this is expensive. It's a list, a test and a freeze.
How Indigo does this. Indigo Unified Communications supports venues including SWG3, Falkirk Football Club (an 8,000-seat stadium where we provide IT support, stadium WiFi, connectivity and telephony) and Wonderworld Group across 10 sites. We build venue WiFi on Ubiquiti UniFi, support EPOS and tills, ticketing and booking systems, CCTV and door entry, and usually have 4G or 5G backup connectivity live within 2–3 working days. We can supply payment terminals and backup SIMs for card terminals too. Out-of-hours and event-day engineer cover is available by arrangement at extra cost. Connectivity for venues →
What to do next

- Book a quiet slot in early November to test your backup connection with real card payments.
- Ask your payment provider about offline mode, limits and a terminal with its own SIM.
- Set a change freeze from the first week of December, and put it in writing for managers and suppliers.
- Get a free IT health check or talk to us about an assessment and we'll review your venue network before the season starts.
Frequently asked questions
How many WiFi access points does a busy venue need?
It depends on the building, the walls and how many devices connect at once, not just floor area. Survey the space with the venue busy, not empty. As a rule, function rooms and bars that fill up need their own access point, and card terminals should never rely on a single access point that guests also crowd onto.
Should card terminals be on the guest WiFi?
No. Card terminals, tills and payment systems should be on their own network, separate from guests, CCTV and staff devices. That improves security, keeps payments running when guest WiFi is busy, and reduces how much of your network falls within scope for PCI DSS, the card industry's security standard.
What happens to card payments if our internet goes down?
Terminals on WiFi or wired networks stop unless you have a backup. A 4G or 5G backup on the router takes over automatically, and a terminal with its own SIM works even if the whole network fails. Some terminals can also store transactions offline up to a limit. Ask your payment provider how yours works.
Has the contactless limit gone up?
The FCA removed the regulatory £100 cap on single contactless payments on 19 March 2026, so banks can now set their own limits. The major UK banks said they would keep £100 for now. For larger bills, customers still insert their card or pay by phone wallet, so check terminals handle chip and PIN quickly.
