I hope I explained all of this and it is understandable.The trouble is I do not own how to put something like this together and also I'm thinking there will be issues with the RFID idea. The RFID scanner will be disguised in the pencil holder base device. It will quickly scan all of the RFIDs in the markers (continually scan all of them every half-second or 500 microseconds), then when it detects a missing RFID tag scan it will detect the expected change and send a signal of the missing marker to the pocket device. RFID tags can be very small and will fit into the back of a Crayola marker.What do you think.. is that 100% possible? For example, the RFID scan is looking for RFID #1, 2, 3, 4, 5, 6, 7 tags,, then when the scan only detects RFID 1, 2, 3, ?, 5, 6, 7 ... #4 is missing so it sends out the signal. This is nice because if two markers are removed at the same time both could be detected.I am worried about RFID. I didn't think it is possible to have an RFID scanner read the 7 or 8 different RFID tags in the markers rapidly fast in microseconds. My RFID scanner can only do 1 scan every 2000-3000 microseconds.Thank you for taking the time to fully read the entire description.
