Dynamic Pricing

Water Park POS & Cashless Wristband System for UK Operators
Posso is a purpose-built water park POS system and water park ticketing software platform designed for the realities of a wet, no-pockets environment. With waterproof RFID wristbands, guests carry nothing but their wrist — yet still enjoy fast entry, cashless spend and keyless lockers across the whole site.
Sell tickets online with timed entry to smooth out arrival peaks, then let guests tap a single wristband for park entry, food and drink, retail and locker access. Because there are no coins, keys or cards to lose by the pool, queues move faster, spend goes up and your team spends less time dealing with lost property and refunds.
Built for UK water parks and aqua parks, Posso unifies water park EPOS, access control, capacity management, season passes and reporting in one connected system. Dynamic pricing lets you adjust ticket and locker rates by weather or demand, while live dashboards show exactly how every wristband, outlet and locker bank is performing in real time.

Water Parks — Frequently Asked Questions
What is a water park POS system?
A water park POS system handles ticketing, cashless payments, locker access and reporting across your site. Posso combines waterproof RFID wristbands, online ticketing, keyless lockers and multi-outlet EPOS in one platform built for wet, no-pockets environments.
How do waterproof RFID wristbands work?
Each guest wears a waterproof RFID wristband linked to their ticket and a cashless balance. They tap to enter the park, pay for food and retail, and unlock smart lockers — all without carrying cash, coins or keys that could be lost in the water.
Do guests still need coins or keys for lockers?
No. Posso lockers are keyless and coinless. Guests open and close their locker with a tap of their RFID wristband, which removes lost-key hassle and the cost of coin mechanisms while keeping dry clothes and valuables secure.
Can I change ticket and locker prices by weather or demand?
Yes. Posso supports dynamic pricing, so you can automatically adjust ticket and locker rental prices based on the weather forecast, day of week or peak demand to protect margins and maximise revenue on busy days.
Does Posso support online ticketing and capacity limits?
Absolutely. You can sell dated, timed-entry tickets online to spread out arrivals, set safe capacity limits per slot, and let guests scan straight through at the gate, reducing queues and improving the guest experience.
Is Posso suitable for UK water parks and aqua parks?
Posso is built for UK operators and scales from single-pool sites to large aqua parks with multiple outlets and locker banks. The platform grows with you and unifies ticketing, EPOS, lockers and access control under one system.
