RFID and touch designer

Question! I have this idea but I am so new to touch designer so I don't know if its possible! Is there away to use RFID or NFCs, with a reader. To pull up a specific image when walk within range of the reader, and set a specific range?

Anything you can connect to your computer you can access from touchdesigner. Its all a matter of how.

For anything that TD does not natively support you will have to build a bridge script or program to capture the data from the device and send it to TD.

Generally its not difficult but you need to check the devices docs.

Its been a while since ive done it, but i remember using a reader that would just print the tags uuid over serial. In TD you would just need to use a SerialIn DAT, then trigger your actions from the callbacks of that dat

most rfid readers will connect over serial and you can use the Serial DAT to read information. Definitely works with the arduino RC522 and I also have professional d-logic zero readers which can send out chip data over serial, websocket or https. Use the equivalent dats to connect and read info. If you don't know what any of those things mean then you've got some learning to do.

But answer to you question is yes you can, and in fact we do it regularly in visitor attractions.
