r/RFID

Hi all I can use some major assistance.

Im trying to see if there's a way I can track my pets micro chip.

I know its a passive RFID, but I dont know if theres any tech that can let me get its signal.

Someone let my cat out the other day please if anyone has any kind of leads this way it will help.

Basically if theres any kinda signal tracker I can make/buy? Or if im just dreaming and what im looking for doesn't exist someone tell me please.

I’m trying to find an access control system that works like a typical hotel RFID keycard setup, but without the RFID electronics being integrated into the lock itself.

Basically, I want the reader mounted on the wall/door frame near the door, while the actual door hardware stays as a normal lockbody (mortise/deadbolt/handle set). Guest taps a card/key fob/NFC tag near the wall reader and the door unlocks.

The goal is to keep the clean “hotel card access” experience, but avoid replacing the entire lockset and have more flexibility with door hardware.

What are these systems typically called, and are there brands you’d recommend for hotels/apartments/Airbnb use?

Would this be an RFID access control reader + electric strike, or is there a better category I should be searching for?

Does anyone have experience integrating Bibliotheca's RFID systems with ILS software? Our public library consortium just migrated to Evergreen ILS and I'm having a difficult time configuring Bibliotheca staffConnect Circ (uplink software needed for Bibliotheca RFID pads to connect with various ILS softwares) to work correctly with Evergreen and am still waiting to hear back from Bibliotheca Support. StaffConnect Circ can't seem to find the correct "target application" to use, presumably because Evergreen is browser based.

I was lead to believe from Bibliotheca's training that RFID pads are glorified barcode scanners in a sense, but Evergreen will not read the barcodes without staffConnect Circ running in the background. Help me to understand: if all we are using our RFID pads for is to scan barcodes (no security activation/de-activation) why do we need to use staffConnect Circ? I'm going to continue my own research into this, but thought I'd throw a plea into the wind in case anyone here is more familiar than I.

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 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

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.

I've got a project I'm working on to read RFID tags on mahjong point sticks and display a point value based on the total it reads from all the tags. Trouble is that I'm running into issues finding an RFID reader that will both connect to a Raspberry Pi Pico 2 and has a read range of ~10cm.

Does anyone know if there's anything like this out there? Especially at a relatively low price point? Everything I'm seeing has a read range of like 2-5cm which doesn't quite cover our point drawers let alone account for the interference caused by the wood of the drawer)

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.
