Robot gatekeeper for authentication prior to meeting attendance

An information processing system for attendee authentication, comprising:

• a robot gatekeeper having a multi-function printer with a memory to store program code including for character recognition and handwriting analysis;
• and
• a processor coupled to the memory and configured to execute the program code to initiate operations for:
• instructing, by the robot gatekeeper, for placement of a hand for a palm vein scanner and placement of a badge for a badge reader;
• reading a badge with the badge reader to obtain first identification information;
• reading a palm of the hand with the palm vein scanner to obtain first biometric data;
• accessing a database to obtain second identification information responsive to the first identification information;
• comparing the first biometric data and second biometric data obtained from the second identification information;
• responsive to at least a threshold confidence level between the first biometric data and the second biometric data, printing an anti-tampering feature on a card;
• scanning a hand written sample on the card;
• and
• analyzing the hand written sample scanned with respect to at least one handwriting exemplar in or associated with the second identification information.
