Papaya POS vs PORTOS:
loyalty with two Slovak POS systems
Papaya POS and PORTOS are both Slovak POS systems, and neither stores Rewardly balances. Both read loyalty live. The difference is that Papaya POS sends the whole bill and PORTOS does not.


The short answer
Papaya POS sends the open bill on each scan, so Rewardly prices the rewards on the real order and a free item lands on the right line. PORTOS asks for the customer's rewards and checks the conditions at the till.
Both let customers pay with credit or cashback and buy rewards with points. Neither shows the member tier at the till.

Why merchants add Rewardly
On both, Rewardly holds every loyalty value and the customer carries the card in Apple Wallet or Google Wallet. Nothing is stored in the POS, so the till always shows the current state.
- Customers add the card to Apple Wallet or Google Wallet in about 10 seconds, with no app to download.
- Businesses on Rewardly see 30% more repeat visits on average.
- Push notifications land on the lock screen, with a 90% read rate.
- One program and one card for all your locations, with results for each location.
- Rewardly does not replace your POS. Sales still run through your till as they do today.
- POS integrations and push notifications are included in the Advanced, Professional and Enterprise plans.
The differences that matter day to day
The bill
Papaya POS sends the whole bill, so product and category rewards are priced by Rewardly. PORTOS sends no bill at redemption, so some reward types are not shown and a product discount applies to one matching line.
Setup
Papaya POS: an API address and access token per location, then three values entered in Papaya POS. PORTOS: the server address, device, user and password per venue, then values in BackOffice or sent to PORTOS support.
Credit
Papaya POS uses all available credit automatically, or only through a chosen product when automatic use is off. PORTOS holds the credit when a reward is claimed and charges what the till really applied when the ticket closes.
Two examples
Illustrative example
A café on Papaya POS
A free croissant reward is applied to the croissant on the bill, even when the order has several other items.
Illustrative example
Two bistros on PORTOS
Each bistro has its own PORTOS server. Both are connected to one Rewardly program, so a stamp collected in one counts in the other.
