Abstract
System and methods of contactless card authentication systems include a contactless card and a client device having an application, a processor, and a card reader. An application on the client device receives a transaction lockdown request, sends a request to the server to begin to allow a transaction approval within a time period, receives the transaction approval via an authentication tap from the contactless card, sends the transaction approval to the server; and receive an allowance or disallowance response from the server.
