I am sure at one time or another you tried purchasing an item using your K-Net or Visa card and the merchant asked from you an extra fee because you are using one of these cards. They would give you the excuse that Visa or K-Net charge them a certain amount for every transaction using these cards and that you need to pay it. Well here is what you the consumer needs to know.
First lets start with K-Net. K-Net is owned by the local banks in Kuwait. They do NOT charge the merchant any transaction fee. So if an item costs KD10 and you pay using your K-Net card, the merchant will get KD10. They will not be charged a single fils by K-Net. This is a fact and you can contact 2431280 if you need any further information on this. If a store tells you that they will have to charge you extra because you are paying with K-Net then you need to report that store to K-Net using the number above.
Now Visa is a different story. Visa DOES charge the merchant 4% for every transaction. This means if you buy an item for KD10, the merchant receives KD9.600. Although the merchant pays 4% for every transaction they do NOT have the right to pass on that 4% to you. According to Visa the merchant should not charge the customer for a Visa transaction and neither are they allowed to set a minimum amount in which you could use your Visa card with. So even if the item you are buying costs 100fils, you can pay with you Visa card. In case a store does try to make you pay the 4% transaction fee, report them to your local bank and they will take care of it. If you would like more information regarding Visa, you will also need to contact your local bank.
Hope this information was helpful.
