General guidance on a simple RFID project build

Projects General Guidance

Hello everyone!

I'd like to construct a device which records times using Arduino and RFID, and even Raspberry Pi need-be

I'd like to place an RFID tag near a sensor
->Placing the tag near the sensor starts a timer
->Removing the tag stops the timer

The time elapsed will be recorded into a spreadsheet or wherever. This is just software and will be worked out later.

I'd like multiple sensors, in different locations.

The idea is, a tag stops at different stations for different durations of time.

The end goal is a table something like this

Is this feasible?
Where should I start?

Is this feasible?

Depends on the RFID reader. Most send an output when the tag is first detected, but do not send an output when the tag moves away.

This does seem to be the obstacle many people have encountered with projects demanding the same goal.

What would be the simplest way of overcoming this?

The RFID tags will be in plastic zip baggies measuring around 9 inches tall by 5 inches wide.

I'm sure this isn't the easiest solution, but I could rig a platform atop a pressure sensor.
The timer would start when pressure is applied to the platform, and stop when pressure is released, and the software would somehow have to associate the tag ID with that time recording.

Depends on the RFID reader. Most send an output when the tag is first detected, but do not send an output when the tag moves away.

Which RFID reader would be capable of this?

At the risk of sounding cheap, I'm willing to pay for guidance.
