Abstract: Systems and methods to provide secure cryptographic authentication, verification, functionality access, and payments between contactless cards and communication devices are provided. An exemplary communication device includes a system on a chip and generates a communication field, displays a prompt to tap a contactless card on the communication device, reads the contactless card after entry into the communication field, performs an authentication of the contactless card, and after a successful authentication of the contactless card, and performs a payment transaction.

Abstract: Example embodiments herein disclose systems and methods for the secure cryptographic authentication of contactless cards by distributed entities. In an example embodiment, a distributed network authentication system can comprises a client node and a distributed ledger node in data communication with the client node, wherein the distributed ledger can contain a database storing a mapping. The client node can receive, from a client device, an authentication request, and responsive to the authentication request, transmit, to the distributed ledger node, a query. The distributed ledger node can receive, from the client node, the query, submit the query to the database, receive, from the database responsive to the query, an identification of at least one selected from the group of a validation node and a validation node address, and transmit, to the client node, the identification.
