    Abstract: Example embodiments of systems and methods for data transmission between a contactless card, a client device, and one or more servers are provided. The contactless card may include one or more processors and memory, which may include one or more applets. The client device may include one or more processors and memory. The client device may be in data communication with the contactless card. One or more servers may be in data communication with the client device. A first set of information may be transmitted from the contactless card to the client device. The first set of information may include one or more links to activate the contactless card via a designated email program. Upon validation of the first set of information by the one or more servers, the contactless card may be activated.

    Abstract: Example embodiments of systems and methods for data transmission between contactless cards and receiving devices are provided. In an embodiment, a contactless card may be configured to create a cryptogram based on a plurality of keys and a counter. The cryptogram may be transmitted to a receiving device. The contactless card may be configured to transmit a one-time password to the receiving device. The counter value may be adjusted each time the one-time password is generated, and the counter may be configured to increment in a non-monotonic sequence, the sequence associated with one or more cryptographic algorithms.

    Abstract: Example embodiments of systems and methods for data transmission between a contactless card, a client device, and one or more servers are provided. The memory of the contactless card may include one or more applets and a counter. The client device may be in data communication with the contactless card and one or more servers, and the one or more servers may include an expected counter value. The client device maybe configured to read the counter from the contactless card and transmit it to the one or more servers. The one or more servers may compare the counter to the expected counter value for synchronization. The contactless card and the one or more servers may resynchronize the counter, via one or more processes, based on one or more reads of the one or more applets. The one or more servers may authenticate the contactless card based on the resynchronization.
