Why market stall EFTPOS fails at the busiest hour
At a night market, the first hour is easy. Stallholders set up, tap a test card and it goes through. By seven the lanes are full, everyone is photographing their food and messaging friends, and the mobile network around the market is congested. Terminals that rely on a SIM card or a stallholder's phone hotspot start taking longer, then declining, and the queue at the stall walks away.
Farmers markets have the same problem in a different shape: a smaller crowd, but often in a park or car park where mobile coverage was never strong. The fix isn't a better hotspot for every stall. It's one market-wide payment network that stallholders join, with the internet supplied by the market.
Three ways to set up market WiFi
Markets differ in budget and layout. Most fit one of these.
Shared payment network for stallholders
One payment WiFi name and password for every stall's terminal, covering all the stall rows. The market supplies the internet; stallholders bring WiFi-capable terminals.
Market office and information tent
A smaller network for the organiser's laptop, raffle or ticket sales and announcements. It suits markets where stallholders handle their own payments.
Both, plus market staff
Payments for stallholders, a staff network for market crew, and the office, each kept separate so staff phones never slow a stallholder's sale.
Market WiFi sizing by stall layout
At markets, layout usually decides the access point count before device numbers do. These examples use our planning numbers and are confirmed on a site walk.
| Market | Payment devices | Layout | Access points (planning) |
|---|---|---|---|
| 30-stall farmers market | About 30 terminals | Two rows in a park, about 1,800 m² | 2 weather-rated, one for each half of the site |
| 60-stall night market | 60–70 terminals and stall phones | One long street with stalls on both sides | 3–4, spaced along the street |
| 100-stall weekend market | About 100–120 devices | A grid of lanes in a car park | 3 for capacity, more where trucks and marquees block the lanes |
| Market office only | 5–10 devices | One tent or container | 1, or simply a 4G/5G router |
Payment terminals use very little data. What matters is coverage at every stall and a connection that holds when the crowd arrives. Plan for the busiest hour, not setup time.

Night market and farmers market WiFi: layout and conditions
Night markets are usually long and narrow: one street, stalls on both sides and a crowd walking down the middle. People absorb WiFi signal, so access points go above head height on stall structures and are spaced along the row rather than bunched at one end. Food trucks and festoon lighting rigs can also block line of sight between units.
Farmers markets tend to be in parks, school grounds or car parks with no fixed line, so the internet comes from a 4G/5G router placed where mobile coverage is strongest, with outdoor access points spreading it along the stalls. Weather-rated equipment matters: early mornings bring dew and summer afternoons bring heat.
For recurring markets, the plan is reused each time. Tell us whether equipment should be packed down after each market or whether there's a secure place to leave it in between.
How market day runs
Stall map
You send the stall layout and the number of terminals. We mark access point positions and where the internet comes in.
Set up before stallholders arrive
Equipment goes in and the payment network is tested from the far end of every row.
Stallholders connect
Stallholders join the payment network as they set up and run a test transaction.
Trading and pack-down
Support during trading is agreed in your plan. After the last stall closes, equipment comes down before the site is cleared.
Questions people ask
Can market stallholders share one EFTPOS WiFi network?
Yes. A shared market payment network lets every stallholder connect a WiFi-capable terminal to one network the market provides. It's kept apart from staff and any public WiFi, and its coverage follows the stall rows. Read more about a dedicated payment network and how it's kept separate.
Why does my card machine stop working at the market?
Card machines at markets often stop working at peak times because they rely on mobile data, and mobile networks congest when a crowd gathers. Phone hotspots suffer the same way. A market payment network with its own internet connection takes terminals off the crowded mobile network, so transactions keep going through when the market is busiest.
Does a farmers market need WiFi?
A farmers market needs WiFi when stallholders take cards and mobile coverage at the site is weak, or congests once the market gets busy. Smaller farmers markets may only need a connection for the market office. A site visit with a mobile coverage test at the location shows which approach makes sense.
Can you set up WiFi for a weekly market?
Yes. For a weekly or monthly market, the network plan, network names and access point positions are set once and reused each time, so stallholders' terminals reconnect automatically. Tell us whether equipment should be packed down after each market or can be left securely on site in between.
Do stallholders pay for the market WiFi?
That's the market organiser's decision. EventWiFi supplies and supports the network for the organiser, who decides whether it's included in stall fees, charged separately or provided free. The market as a whole is quoted after we review the stall map and the site.
How many access points does a night market need?
A night market usually needs access points spaced along the stall rows, because layout decides the count before device numbers do. Payment terminals use little data, but every stall needs coverage. A 60-stall market along one street might need three or four access points; the exact number is confirmed on a site walk.
