Abstract
Example embodiments of systems and methods for data transmission between a contactless card, a client application, and a server are provided. The memory of the contactless card may include a first card number table storing a first plurality of card numbers, each card number associated with a user account. A first applet may cycle through the first card number table and transmit each of the first plurality of card numbers to a second applet. In response to detection of one or more gestures by the card, the client application may read one or more of the first plurality of card numbers from the second applet and transmit a verification request associated with the one or more read card numbers to the server, which may compare the one or more read card numbers to a number from a second card number table and transmit a verification determination to authenticate the card.
