[FRC Blog] 2025 Rule Updates - RFID

“802.3af”

But… But… Active POE isn’t legal, so devices couldn’t use it!

So happy that’s now legal.

Allowing NFC on bot is really cool too.

Still unsure whether it’s a GOOD idea or a BAD idea.

But now we need a radio and a limelight to take advantage of it!
@kiettyyyy “VH-110” and/or “VH-114” with 802.3af support?
@Brandon_Hjelstrom “Limelight3g+” or “Limelight4” with 802.3af support?

From what I see there are no rules on what you can use them for…

Tap your credit card before the match and pay $2.99 to use a multi-piece auto

You want a faster drive speed? Gonna have to complete a transaction on each drive motor to unlock the faster speed

If you actually think about it, you could have separate NFC cards to tell your robot certain things, like instead of using your dashboard, you just have a NFC card that tells your robot what auto to run

The first thing I thought of is battery tracking, put an NFC or RFID tag on each battery and read it on code startup

Its funny, in our team discord today we were talking about implimenting a battery scanner with unique nfc tags. And then realized no non radio based rf is allowed on the robot

Few hours later and boom

In FRC it’s not as easy to implement since there isn’t an easy to use Java API for most readers, there’s several other ways reading the data but I’m interested to see how teams make use of it

Seems pretty doable over i2c fo the rio

If I2C wasn’t so unreliable on the Rios

im wondering what led to the change to R707. in what scenario would RFID or NFC be used entirely within the robot during a match?

my first thought was batteries

RFC can transmit power as well as data. Perhaps a sensor or flashlight on a turret?

There are plenty of common industrial uses for RFID in things like proximity sensors. They can be much friendlier (less fragile, less finicky, contactless) than some of the legacy limit switch implementations that have been common in FRC. It’s a no-downside move to legalize those types of devices even aside from the obvious battery tracking suggestion that everyone has pointed to.

what are some uses people can see from rfid or nfc tags? maybe they are integrating them into game pieces?

Please not again
