Beacons & BLE
Beacons that plug into the loyalty programme you already run
Small Bluetooth beacons in your stores, and the software and data behind them. Nothing to replace: they add to the loyalty system and app you already have. We supply the hardware, set it up and deliver the data.
-
Loyalty card on the lock screen
As a customer walks in, their loyalty card appears on the lock screen, ready to scan at the till. No searching through apps.
-
Zones and time spent
Beacons connect to the app over Bluetooth and measure which zones people visit and how long they stay, so you see what the layout and the promotions really do.
-
Beacons on shopping carts
When few customers carry the app, a beacon on the cart measures the same journeys. Every visit counts, phone or no phone.
-
Custom BLE solutions
Presence, access, asset tracking or something only your business needs. We design the hardware setup and build the software around it.
- We supply
- Beacons, gateways and the setup in store
- You get
- The data: dashboards, exports or a feed into your systems
- Works with
- Your loyalty app and cards, on iOS and Android

Questions
Answers to the questions we hear first
Where we are, what we build, what things cost and how beacons fit into a loyalty programme. Anything else, just ask.
Where is Viallo based, and do you work with clients outside Slovakia?
We are based in Bratislava, Slovakia, and work with companies across Europe. Meetings are online or in person in Bratislava and Vienna, and we work in English and Slovak.
What does Viallo design and build?
Product design, web applications, SaaS platforms, iOS and Android apps, websites and Bluetooth beacon solutions for loyalty programmes. We also build our own products: Booking Desks for hybrid offices and Routava for drivers.
How long does a project take, and what does it cost?
A website takes a few weeks, an app or a platform a few months. After a discovery call you get a fixed quote and a timeline, and you see the product take shape in regular demos.
How do beacons work with our loyalty programme?
A small Bluetooth beacon in the store makes the customer’s loyalty card appear on the lock screen as they walk in, ready to scan at the till. Beacons add to the loyalty app and cards you already have. Nothing is replaced.
What do the beacon plans cost?
Plans start at €59 per store a month with the hardware included. Insights, with zones, time spent and footfall, is €199, and Engage, with offers on the lock screen, is €349. A pilot in two stores for three months costs €2,900 and is credited when you roll out.
Do our customers need a new app for the beacons?
No. The loyalty card lives in Apple Wallet and Google Wallet. Zone and time measurement uses the app you already have, and a beacon on the shopping cart counts the visit even without a phone.
Is the data GDPR compliant?
Yes. Viallo is an EU company and the data stays in the EU. Measuring an individual customer needs their consent in the app, and cart beacons are anonymous.
Can you take over a product that already exists?
Yes. We review the code and the design first, then continue in short iterations with regular demos, so you always know where the project stands.
