"Non-EMV" refers to payment methods or technologies that do not comply with the EMV standard (Europay, MasterCard, Visa) for chip cards and contactless payments. EMV is an international standard that governs the security of chip cards and their associated payment terminals. Since non-EMV payments lack the advanced security features of EMV chips—such as dynamic data generated for each transaction—they are more susceptible to fraud, particularly skimming (unauthorized copying of card data). These increased risks may require additional security measures and lead to higher fees.
