OPI (Open Payment Initiative)
OPI (Open Payment Initiative) is a protocol that standardizes the integration and communication between POS systems and EC terminals. It enables a seamless and fast connection between the POS system (point of sale) and the payment terminal so that payment information can be exchanged securely and efficiently. For merchants, OPI means a simplified and flexible connection, as different POS systems and terminals can communicate with each other without any problems. This reduces technical hurdles and enables smooth processing of card payments. OPI is particularly advantageous for merchants with more complex systems or multiple payment stations, as it facilitates the integration of different systems and minimizes maintenance costs.
