Systems and methods for secure read-only authentication
First Claim
1. A transaction card associated with a financial account and for generating an encrypted value as part of an authentication request, the card comprising:
- a radio frequency transmitter;
a clock generator coupled to the radio frequency transmitter, the clock generator being configured to increment a counter value responsive to a wireless read signal received from an external radio frequency reader device; and
a near field communication tag coupled to the radio frequency transmitter and storing a permanent identifier and the counter value;
wherein the near field communication tag is configured, in response to the received read signal, to;
generate an encrypted value based on the permanent identifier and the counter value; and
provide the encrypted value to the radio frequency transmitter for transmission to the external radio frequency reader device.

Abstract
A system for authenticating a user with a mobile device comprising a memory storing instructions, and a processor in communication with a network. The processor may be configured to execute the stored instructions to receive, from a mobile device, an authentication request; obtain, from a database, a permanent identifier associated with a transaction card; generate a temporary identifier associated with the transaction card; generate an expected value by encrypting the permanent identifier and the temporary identifier; verify the expected value against an encrypted value received from the mobile device; and transmit an authorization command to the mobile device.
