There's honestly plenty of security features on a magstripe card that it isn't strictly NECESSARY to have EMV to identify cloned/counterfeit cards. The issue is you need to have an interest and be pretty darn knowledgeable to spot them manually. EMV can spot them for you, with a much greater success rate.
