The Cooperative Bank of Chania is participating in the new nationwide promotional campaign launched by DIAS, under the slogan “Everyone Loves Winning with IRIS”, offering its customers the opportunity to win supermarket vouchers worth €1,300 every month simply by using IRIS Payments for their everyday purchases.

The campaign begins on 26 October 2026, will initially run for three months, and is organised by DIAS in cooperation with the participating banks. As part of this initiative, each participating bank will select one lucky winner through a monthly prize draw, who will receive supermarket vouchers with a total value of €1,300.

How to Enter the Prize Draw

Participating is simple. Every time a customer makes a purchase at a physical store and chooses to pay using IRIS Payments at the POS terminal, they automatically receive one entry into the prize draw.

To complete the payment, customers simply need to select IRIS Payments as their payment method at checkout and scan the QR code displayed on the POS terminal using the ChaniaBank mobile app.

Each transaction made through IRIS Payments counts as one entry, giving customers more chances to win the more frequently they use the service for their purchases.

Easy, Fast and Secure Payments

IRIS Payments is a modern Greek instant payment solution developed by DIAS in cooperation with the country’s banking sector.

The service enables consumers to make payments directly from their bank accounts using their bank’s mobile banking app, without the need for cash or a payment card.

By participating in this initiative, the Cooperative Bank of Chania supports the wider adoption of modern digital payments and encourages consumers to use IRIS Payments for their everyday transactions, helping to promote innovative payment solutions in physical retail stores.

Participation in the prize draws is subject to the terms and conditions of the promotional campaign, which are available on the Bank’s website.
