1. A method of authentication, the method comprising the steps of:
transitioning, by a first applet of a contactless card, through a first plurality of card identifiers;
transmitting, by the first applet to a second applet, the first plurality of card identifiers; and
transmitting, by the second applet and after one or more entries into a communication field, the first plurality of card identifiers for verification,
wherein each of the card identifiers from the first plurality of card identifiers are transitioned in a sequential manner.
