So what do we need to collect the numbers? We need the RFID-Skimmer app.
- Runs on a small laptop of maybe a phone.
- Connects to an RFID reader.
- Records sound and image from a hidden webcam.
Scenario: I have my reader conceiled in my sleeve. My cam somewhere else on my body. When I meet someone I'd like to skim, I just move close to the person and murmer apologies when I get too close. The apologies are handy to identify the person later. "Oh sorry mr. Cohen" later help me to combine some uuids with our mayor.
The app could constantly spool AV. As soon as a tag is detected, the AV from the previous 30 sec. is archived with the RFID number + timestamp. The archiving stops 30 secs after the detection of a tag.
This way I can easily skim lots of people in a crowd, say, at a Picnic event.
