The trigger may relate to the device being within a threshold proximity of a point of sale device. The device may provide a dynamic card identifier associated with the device based on detecting the trigger to perform the contactless transaction. The device may exchange data, with the point of sale device after providing the dynamic card identifier, to perform a mutual authentication to establish a secure session. The data may be encrypted based on a dynamic diversified key associated with the dynamic card identifier. The dynamic card identifier and the dynamic diversified key may be valid for a threshold period of time and may be invalid after the threshold period of time. The device may perform the contactless transaction via the secure session based on exchanging the data to perform the mutual authentication to establish the secure session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure contactless card emulation","description":"A device may detect a trigger to perform a contactless transaction.
