What consumers and sellers need to know regarding the novelty of the IRIS payment system in Greece.

Starting November 1st, 2025, all businesses in Greece—including physical stores and e-shops—must accept IRIS payments, which allow consumers to instantly pay from their bank accounts via mobile phones, bypassing traditional card entry. POS systems must be software-upgraded to support IRIS, enabling fast, secure payments and automatic receipt issuance, enhancing tax transparency through integration with cash registers.
