1. A user alert method, comprising:
detecting, by a first sensor, a card insertion into a card reader;
transmitting, by the first sensor, a first notification to a processor, wherein the first notification indicates the card insertion;
initiating, by the processor, a session upon receipt of the first notification;
detecting, by a second sensor, the absence of the user within the vicinity of the second sensor;
transmitting, by the second sensor, a second notification to the processor, wherein the second notification indicates the absence of the user;
transmitting, by the processor, a message indicating the card insertion upon receipt of the second notification, the message including a code;
maintaining, by the processor, the session for a period of time following the transmission of the message;
receiving, by the card reader, entry of the code;
transmitting, by the card reader, a third notification to the processor, wherein the third notification indicates the entry of the code;
transmitting, by the second sensor, a fourth notification to the processor, and
instructing, by the processor, the card reader to release the card.
