All-in-One POS: How the POS in the Payment Terminal Works

It's Saturday night, the terrace is fully booked, and the pace in the dining room is intense. Your best server takes an order for a party of six. Instead of immediately sending the order to the kitchen and moving on to the next table, they have to turn around, cross the dining room, and stand in line behind a colleague at the stationary POS computer. When it's time for the guests to pay, the procedure repeats: fetch the bill from the POS, find an available payment terminal, walk back to the table, take the payment, and finally walk back to the POS to print the physical receipt.

This endless running around is not just exhausting for the staff; it is a massive time thief that lowers your table turnover and creates unnecessary bottlenecks. The solution is an all-in-one POS system. With Vendion AIO, the entire POS moves out onto the floor, right into the pocket of your waitstaff.

What exactly is an all-in-one POS system?

When we talk about a POS in the payment terminal, we don't mean an old-fashioned solution where a payment terminal can fetch a bill from the POS (what the industry calls Pay@Table). We mean a fully-fledged POS computer compressed to the size of a modern smartphone, but with one crucial difference: it has a built-in receipt printer and card reader.

Vendion AIO is built on the market-leading Adyen S1F2 hardware. This device runs the entire Vendion POS software. This means the staff has access to the exact same features as on the large screen at the bar. They can open tables, add modifiers (like "extra sauce" or "meat medium rare"), send tickets directly to the kitchen's KDS screens, split bills, and take payments via chip, tap, Apple Pay, or Swish. Everything happens in one single device, and when the guest wants their receipt, it prints directly from the top of the terminal.

In other words, you don't need separate devices for taking orders and taking payments. You don't have to balance a tablet in one hand and a payment terminal in the other. Everything is integrated into the same system, eliminating the risk of integration issues and incorrectly entered amounts.

How a handheld POS changes the restaurant workflow

Implementing a handheld POS in a restaurant fundamentally changes the dynamics on the floor in 2026. Let's look at the concrete numbers. Every unnecessary trip to a stationary POS takes an average of 1 to 2 minutes. If a table requires four interactions (drink order, food order, dessert/coffee, payment), it means the staff spends up to 8 minutes per table on pure logistics – time when their backs are turned to the guests.

By letting the staff do everything at the table, this time is completely freed up. The server can stay in their section. When a guest orders an extra round of beers, it's fired directly to the bar with the push of a button, and the drinks can be on their way out before the server has even left the table. This immediate service demonstrably leads to higher average checks, as the threshold for upselling becomes non-existent.

When it's time to take payment at the table, the experience becomes frictionless. The guest asks for the bill, the server pulls out their AIO device, shows the bill on the screen, lets the guests split the amount if they wish, takes the payment, and hands over the receipt in under a minute. The table becomes available for the next party faster, which is critical for profitability during the year's busiest weekends.

From food truck to à la carte: Who needs Vendion AIO?

An all-in-one POS system is not just for large restaurants with sprawling terraces. It is a revolution for businesses where space is a scarce commodity.

Do you run a food truck or a small coffee bar? Then you know how valuable every square centimeter on the counter is. With Vendion AIO, you can throw out the iPad stand, the bulky receipt printer, the tangle of cables, and the separate payment terminal. Your entire operation fits in a device you can hold in your hand. You take the order, take the payment, and provide the receipt from the same machine. It gives a cleaner impression to the customer and makes closing incredibly much smoother.

For the à la carte restaurant, it's instead about the level of service and discretion. Avoiding large POS stations placed around the dining room creates a more elegant environment. The staff works seamlessly with their terminals, and all data syncs in real-time. Whether a colleague updates the menu in the bar or a guest orders via a QR code, it instantly appears in all AIO devices.

Economics and hardware: Less tech, more value

Investing in old technology where you have to buy separate screens, card readers, and printers quickly adds up in cost. Furthermore, the risk of technical issues increases with the number of devices that have to talk to each other over a network.

With Vendion AIO, you get a robust, industrial-grade device for 790 SEK/month. It is built for the restaurant environment, withstands spills and drops, and the battery lasts for a full shift. And because we know the industry demands flexibility, we naturally work entirely without lock-in periods. You can scale up with more units for the summer season and scale down when autumn arrives.

Everything in the same system

Perhaps the biggest advantage of a genuine all-in-one system is that you avoid third-party solutions. With Vendion 360, the AIO unit is a natural extension of your total ecosystem. It talks seamlessly with your kitchen system (KDS), your inventory management, and your accounting.

Stop letting your staff act as messengers between the table and a locked-down computer. Give them the right tools to maximize both sales and the guest experience. A POS system in the payment terminal is not the future – it is the standard for profitable restaurants in 2026.
