IPS Assist allows merchants to use additional opportunities to attract customers in the form of advertising campaigns. Merchants can conduct advertising campaigns aimed at promoting certain goods (services) independently (or together with banks). By purchasing such goods (services) the customer is provided with an agreed discount, subject to payment with a card of a certain type. The promotion may also include prize drawings for customers depending on the number of purchases in certain stores and payment for these purchases with certain types of cards. Promotions have time limits set by the organizer.
