Market traders and street food: taking payments where there is no Wi-Fi

The single biggest cause of lost street-food trade is a terminal that cannot get online at the exact moment the site fills with people. Phone hotspots are the classic failure: they work perfectly during setup at nine in the morning and collapse at one o'clock when three thousand people arrive with three thousand phones on the same cell.

A terminal with its own built-in 4G and Wi-Fi fallback is a different proposition, because it is not sharing your phone's connection or fighting the venue router. In a covered market, a car park, a festival field or a Christmas market shed, that is the difference between trading and standing there apologising.

It is also worth knowing what your terminal does when connectivity drops for thirty seconds. Whether it queues, retries or simply fails is something to ask about before the day, not during it.

A full trading day on one charge is the practical requirement, and it is one that gets quietly missed. A terminal that needs a power bank at two o'clock is a terminal that will be flat at four on the busiest day of your year.

Screen visibility in daylight matters more than any feature list. So does whether the machine can be operated quickly with cold hands in November, which is when Christmas markets happen and when a fiddly interface costs you real transactions.

Physical robustness is the last one. Street trading involves rain, grease, being knocked off a counter and being packed into a van at midnight. Buy for that reality.

Street food has an unusually hard throughput ceiling: the queue is visible, and people join it or walk past based on how long it looks. Shaving two seconds off each transaction does not just save time, it changes how many people are willing to join the line in the first place.

Teya Pro is built for quick contactless, chip & PIN and mobile wallet payments.

Events cluster. Saturday's market funds Sunday's stock, and a two-day festival requires a restock overnight. If your card money arrives on Tuesday, you are funding the second day out of savings or a credit card.

Teya settles card takings the next working day as standard, and qualifying businesses can choose everyday or Instant Settlement options, with conditions and in some cases an extra charge. For traders working a summer of back-to-back events, that alone can be the difference between working one event a weekend and two.

A lot of successful street food ends up in a permanent unit, a second trailer or a franchise pitch. The problem is that traditional lenders are unenthusiastic about businesses with no fixed premises and lumpy seasonal income.

Turnover-linked funding is assessed on card takings and repaid as a share of them, which suits a trader with a strong summer and a quiet January far better than a fixed monthly repayment set in August.
