Systems and methods for optimizing short-range wireless read of contactless cards using video signal

A method of optimizing near-field communications with a contactless card, the method comprising:

• activating one more optical cameras on a reader device upon detecting a contactless card within a near-field communication range of the reader device;
• identifying the contactless card, by detecting a rectangular form, at a first position within a view field of the one or more optical cameras;
• determining, based on a light sensor output associated with the reader device, a light intensity value associated with the view field comprising the contactless card;
• computing a trajectory of the contactless card, based on one or more transitions in the light intensity value, as the contactless card moves within the view field of the one or more optical cameras;
• predicting, upon detecting the light intensity value dropping below an intensity threshold value, a second position of the contactless card based on the trajectory;
• initiating, upon determining that the second position of the contactless card corresponds to an optimal wireless alignment with the reader device, a wireless scanning process associated with the reader device;
• and
• generating, upon determining that the second position of the contactless card does not correspond to an optimal wireless alignment, one or more user notifications with respect to the optimal wireless alignment.
