Chania Cooperative Bank is taking part in a new nationwide promotion by DIAS, under the slogan “Everyone loves winning with IRIS”, giving its customers the chance to win supermarket vouchers worth €1,300 each month by making their everyday purchases with IRIS Payments.
The promotion starts on 26 October 2026 and will initially run for three months. It is being organised by DIAS in cooperation with the participating banks. As part of the initiative, each participating bank will select one lucky winner in a monthly draw, who will receive supermarket vouchers worth a total of €1,300.
How to enter the competition
Taking part is simple. Each time a customer makes a purchase at a physical store and chooses to pay via IRIS Payments at the POS terminal, they earn one entry in the draw.
To complete the payment, they simply select IRIS Payments at the till and scan the QR code displayed on the POS terminal screen using the ChaniaBank mobile app.
Each IRIS Payments transaction counts as one entry, giving consumers the chance to improve their odds of winning the more often they use the service to make purchases.
Easy and secure payments
IRIS Payments is a modern Greek instant payments solution developed by DIAS in cooperation with the country’s banking system.
The service enables consumers to make payments directly from their bank account using their bank’s mobile banking app, without the need for cash or a card.
By taking part in this initiative, Chania Cooperative Bank is supporting the wider adoption of modern digital payments and encouraging consumers to use IRIS Payments in their everyday transactions, helping to boost the use of innovative payment services in physical shops.
Entries in the draws are subject to the terms and conditions of the promotion, which are available on the Bank’s website.
