1. A device for secured interaction processing, comprising:
a memory operable to store:
a baseline optical emission pattern representing a secured operation for interaction processing; and
a plurality of known malicious IP addresses; and
a smart chip, operably coupled to the memory, comprising:
one or more optical cells configured to measure optical emissions from hardware components inside the device; and
a processor configured to:
access, from the one or more optical cells during a first interaction in real time, a first measurement of first optical emissions, the first optical emissions being generated by one or more first hardware components inside the device responsive to an interaction between a first data card and the device during the first interaction;
generate, during the first interaction in real time, a first optical emission pattern based on the first measurement of the first optical emissions;
determine, during the first interaction in real time, whether the first optical emission pattern matches the baseline optical emission pattern based on a comparison between the first optical emission pattern and the baseline optical emission pattern; and
based on determining whether the first optical emission pattern matches the baseline optical emission pattern:
if the first optical emission pattern does not match the baseline optical emission pattern:
 decline the first interaction; else
if the first optical emission pattern matches the baseline optical emission pattern:
 identify, during the first interaction in real time, card information associated with the first data card; and
 determine, during the first interaction in real time, whether the first data card is associated with one or more prohibited interactions based on the card information; and
 based on determining whether the first data card is associated with one or more prohibited interactions:
 if the first data card is associated with one or more prohibited interactions:
 decline the first interaction; else
 if the first data card is not associated with one or more prohibited transactions:
 access, during the first interaction in real time, the plurality of known malicious IP addresses from the memory; and
 determine, during the first interaction in real time, whether the device is connected to any one of the plurality of known malicious IP addresses; and
 based on determining whether the device is connected to any one of the plurality of known malicious IP addresses:
 if the device is connected to any one of the plurality of known malicious IP addresses:
 decline the first interaction;
 else
 if the device is not connected to any one of the plurality of known malicious IP addresses:
 approve the first interaction.
