r/RFID

Hi everyone!

Just got my first ever Bambu Printer with AMS combo and now I’m looking to be lazy af with loading spools haha.

Love the idea of how the AMS can auto read and load Bambu filaments thanks to the chips but hate how limited Bambu filaments are. I have checked and a lot of my third party ones I live need nearly if not totally identical settings as the Bambu Filaments. So I figured I would just add the tags into the spool and call it a day.

That means I’m now looking to get one of every colour in:
- pls basic
- pla matte
- pla tough
- pla silk
- pla translucent
- pla wood
- pla metal
- pla marble
- pla silk multi colour
- pla glow
- tpu for ams
- petg basic
- petg translucent.

If anyone has some advice on the best way to get my hands on this many of tags, please reach out because I’m still learning! Thanks!

hello! i am an engineering student and i had a funny idea. i want to put my debit card information onto the NFC chip in a top golf ball so i can pay for things with a golf ball. i have somewhat of an idea of how NFC and RFID works, but i have no experience working with it and not much technical knowledge on it. that being said, i think i can learn it if given a project.

can this be done? is there a way to take my own information off my debit card and encode it into a top golf ball the same way the encoding machine in the ball dispenser would program an ID into the balls?

EDIT: so the balls at top golf already have an NFC chip in them. the process of putting the chip in a golf ball isn't the problem, its putting the token onto the NFC chip. ​

i just want to see the look on their faces the next time i go to dutch bros

So I had an employee bring me a card that was absolutely wrecked, cracking and falling apart. I removed the shell and have down to a chip with copper antenna glued to a plastic piece. What is the coolest thing I can do with it? I am tempted to sew it into a glove but then I would have to wear gloves at work. What are your thoughts?

Hi! I am trying to duplicate my key card and put in a more convenient keyfob. But I don’t know what’s the right keyfob should I buy and the right reader.

I bought (Handheld 125KHZ RFID Card Copier Writer Duplicator Programmer Reader + EM4305 T5577
Rewritable RF…) for reader and (YARONGTECH Waterproof ABS 13.56MHz ISO14443A M1 Chip S50 NFC RFID Token Keyfob Tag)

I don’t know if it’s compatible but can someone guide me through the process. It seems not working.

Thank you.

Hi yall my work uses the card mentioned up above to game access to our facility and I would like a digital set on my phone. I have an iPhone for now but I would also like recommendations for android. What would be the best way y’all recommend doing that? I do have full permission from my boss due to him having the same thoughts.

With budget contraints I need to build and deploy multiple uhf fixed reding stations to register timestamps when an event occurs, for multiple boxes, 500 at same time.
So instead of ideally calling an integrator and buying up to date equipment, I must buy used Impinj speedway ipj r1000 readers or similar (motorola (not zebra) FX7500 ). Old, mostly deprecated but still functional. Off course they cannot manage Impinj Connect or modern software due to licensing/vendor limitations.

Truth is that my job is to make it work. There is a python package to manage LLRP `sllurp`.

Question: does any of you guys have experience with that kind of hardware, I must read reader payload, and send it to a cloud rest api endpoint, via MQTT where it can be filtered and stored. As afar as I know the readers are closed, so a machine must be connected to each one, ideally a Linux machine, to read LLRP, process, and send.
What I'm not sure is about the feasability if extracting data wirh python code. Any ideas, opinions, recommendations, criticisms, whatever...
