Proface HMI PFXGM4301tad connectivity with badge reader

Good afternoon,

I currently have a Proface PFXGM 4301tad HMI that I'm using with a Mircrologix 1400 PLC. My question is the USB A port only to be used for a memory card(flash drive) and nothing else? I have 2 different badge readers that I'm looking to implement for operator traceability. One of the readers connects via USB A and the other uses serial connection. I came from an OMRON background so I am still learning both of these platforms. With OMRON I could connect the NS HMI and the badge when activated wrote to extended memory. I can't seem to figure out where or if this is writing to anything or where it is. END GAME: to swipe a badge and log that badge number.
