Need to send a file of strings to fill a vector of strings on Arduino board

For my project (Enable/Disable an access to people based on access RFID code) I need to periodically send a list of strings (with start code < and > end code) from a PC to Arduino via the serial link in order to fill a vector of granted access hex strings. The list changes during the day and the vector should periodically refreshed. Any idea? Thanks in advance. Carlo

that's entirely possible

I would suggest to study Serial Input Basics to handle this
