1. A smart textile garment comprising:
a smart textile pocket, wherein the smart textile pocket comprises a first pocket side and a second pocket side;
a first near field communication (NFC) transmitter embedded in the first pocket side;
an NFC receiver embedded in the second pocket side;
an electromyography (EMG) sensor embedded in a sleeve of the smart textile garment, wherein the EMG sensor indicates a physical movement of a hand of a wearer of the smart textile garment in real time;
an event processor coupled to the first NFC transmitter and the NFC receiver to detect a change in an NFC signal strength between the first NFC transmitter and the NFC receiver, wherein the change in the NFC signal strength between the first NFC transmitter and the NFC receiver indicates that an object has been removed from the smart textile pocket, wherein the event processor correlates EMG sensor readings from the EMG sensor and the NFC signal strength between the first NFC transmitter and the NFC receiver to determine that the object has been removed from the smart textile pocket without use of the hand of the wearer of the smart textile garment, and wherein the event processor generates and transmits an event signal in response to determining that the object has been removed from the smart textile pocket without use of the hand of the wearer of the smart textile garment; and
an alert device, wherein the alert device emits an alarm in response to receiving the event signal from the event processor.
