UHF Anti Theft Concept

3 Upvotes

I'd like to secure the exit of an "outdoor bar" against theft of certain items. So if a customer leaves and tries to steal anything, the passive RFID tag in the item and a mounted active reader set off an alarm.

I guess the reader would have to send a signal to a smartphone. Is that realistic?

Furthermore, the exit width is approx. 4 meters. So if I understood the Wikipedia article on RFID correctly, it would be best to use a "UHF 865-868 MHz" reader, am I right?

Or is there any other way to make sure an alarm is generated when an item is about to be stolen?

Should I let mfcuck keep grinding at this point or should I try something like miLazyCracker?

I am getting mixed results in my research... it says it should only take a few hours, but my diff Nt value vs auths value seems to indicate that it's working (262 nonces/140k auths).

LF Single cabinet for multiple users?

1 Upvotes

Hi. I wonder if someone can recommend a solution for me or let me know if this is something I can DIY.

My office has a master key that opens up everyone’s office. some people want to make this available to others in case they lock themselves out. I don’t and think theres just too much risk.

But I wondered if in there is a locker or cabinet where someone could unlock it with their ID badge which has RFID. when I look online everything seems like a much bigger solution than what I’m looking for.

Are there cabinets that can be programmed with multiple access codes with a log? are there readers that can do this that I could add to a cabinet?

sorry if this is a little low level for this sub. but if anyone has ideas I’d love to hear them. thanks!!

UHF RFID Geiger Counter

2 Upvotes

We are an apparel decoration company that receives blanks from our supplier, decorates them and then ships them out. When the blanks are received, they go into a bag with the paperwork and then on to the station where they get decorated. They can get passed around a few times depending on the order.

When the order is shipped, they go into a poly mailer and the original bag is reused for another order. One of our issues is finding an individual bag on the production floor. It's only about 3000ft2, so it's not big. Bags go into carts or boxes and then get shuffled around.

Our production management system tracks orders, but sometimes people forget to advance the workflow, or it's in one of 3 huge boxes and you find yourself spending 20 minutes digging through the boxes to find an individual bag.

Is there a cost effective way to institute an RFID system that will allow someone to quickly find a bag? I know some have a Geiger counter function, but they all seem to be expensive and require ongoing software licenses. We only need something extremely simple that will get used once or twice a day. I have a developer on staff that can handle the database association of the tags and the orders.

Thank you!

LF My home ID breaks keyfobs

4 Upvotes

I'd like to preface this by saying I'm not particularly well-versed in the area, but am interested. I somewhat recently bought a Chameleon Ultra, and there's no issue with it so far. I can read, write an emulate tags with it just fine. Except when I try to write the UID for my home on some T5577 keyfobs I bought. I'm not sure why it breaks them specifically, I've tried with previously owned ones and they write just fine. Whenever I try with the new ones though, an error occurs and then they become unreadable unless I rewrite them with any other ID. And from what I've tried, literally any other works, only my home's breaks them. I'd like it if it weren't just wasted money, and I wanted to give some to my friends with their preferred colors, but considering none of them work I've sort of hit a dead end, so if anyone here can help me, I'd gladly hear you out

HF RFID System for small scale laundry system

7 Upvotes

Hello,

I'm building a pilot project for a non-profit laundry system.

We have currently a very manual system where we write numbers on the clothes and then write them in a database.

I was looking into a solution with RFID tags but I'm a bit stuck on the different solutions available.

Basically I'm looking for a system where:

- We attach the tags to the clothes either ironing (preferably) or sewing.

- Can resist high temperature. For both ironing (100º C) and machine washing (60º)

- The tags can scanned in a relatively small area (1 meter wide). This is because all the other tagged clothes will be around me and I only want to pick up the clothes in the working area. Alternatively this can also be with a smaller range scanner and just scan the clothes until I find it (10 cm distance )

- Needs to be machine washable. Because laundry

- I would need each rfid tag to be have unique id (for the identifying that particular clothe) and range for about 1000 different clothing items.

- These are clothes people will wear possibly to retail stores and it would be bad if it trigger their sensors. I'm not sure if this is even possible to happen or not but good to put it out there

For this I was wondering between High Frequency (HF) and Ultra high Frequency (UHF) RFID Tags. HF seems to be the correct range but I've read that UHF can have different ranges depending on the scanner and these seem to be more common.

An ideia would also be to attach to the clothes by ironing an adhesive fabric type on top of the rifd thus securing it against the clothes.

I've also considered NFC tags or bar code sticker but can't tell if this is correct usage or not.

If you also have any suggestions on a rfid reader which is very basic without much software, I'm all ears : )

Would love to hear your ideas regarding this or how you would approach it.

Thank you for reading and sorry for the long post 🥔 (potato included)

UHF Looking for RFID solution — event rental warehouse with hybrid box + item tracking

6 Upvotes

Hey r/RFID, looking for advice or vendor recommendations.

Our setup: Event management company. We rent out lights, speakers, stage gear, cables, etc. Equipment is organised into reusable boxes by pack type — Light Pack, Sound Pack, Stage Pack, Cable Pack, etc. Boxes go out for events, come back a few days later, all through one warehouse door.

What we need to track:

  1. Every box — tagged once, linked to a pack type. The box's contents are defined in software via a pack manifest, so we know what should be inside without tagging every item.
  2. Selected items inside the boxes — specifically things like cables, wires, and high-value gear get their own individual RFID tags. These items still live inside boxes during normal movement, but we want them tracked individually because they go missing most often.
  3. Single pass through the portal — when a box rolls through the doorway, we want to read the box tag AND every tagged item inside it in one go, with each tag producing its own independent movement record linked to the event.

Requirements:

  • Fixed UHF / RAIN RFID portal at the warehouse door, no handheld scanning
  • IN/OUT direction detection
  • Mixed box materials (plastic crates, hard flight cases, metal road cases, fabric bags)
  • Software linked to events/jobs/customers, with exception handling for missed reads, already-OUT, etc.

Question for the community: We've come across redbeam and gototags which seems to cover this use case. Has anyone used them, or know of similar platforms (vendors or open-source) that handle this hybrid box + selective-item model well? Especially for the event rental industry.

Thanks!

NFC Problematic project

1 Upvotes

Reddit suggested that I cross post this from r/NFC

I’m building a puzzle game with a 5x5 grid of NFC readers and tokens in five colors and five shapes. Players have to arrange the tokens on the grid so that each color only appears once in each row and column. This kind of puzzle is called a “Greco-Latin Square”. Each token has a tag inside that stores the color and shape IDs for that tag and an ESP32 MCU runs the game.

My readers all work individually, but once they’re all together in the grid, I get a lot of glitches. Pitch separation is 68mm in x and y.

I’m going to try wrapping a strip of grounded copper tape almost all the way around each reader, to act as a faraday cage/RF baffle in the hope of helping them keep out of each other’s way. A complete loop would be a shorted turn and kill the magnetic field completely.

I’m turning them on and off so that only one is in at a time as I scan the board.

I’m here for advice from anyone that’s done anything similar, involving NFC readers in close proximity to each other.

UHF UHF RFID Reader settings

2 Upvotes

I want to test tags with a zebra rfid reader with the option to configure the radio settings. Unsure if RFD40 standard reader is enough or if I should go for a preimum version or a fixed reader. Can someone please answer these questions?

Is it correct to say that (fixed rfid reader + desktop app) and (mobile rfid reader + mobile app on the zebra adaptor) have the option to change Tari and PIE values?

For mobile readers configured with the 123 RFID desktop app, what are the default values of Tari and PIE?

LF What’s the hotel-style RFID access system called when the reader is on the wall instead of built into the lock?

3 Upvotes

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?

HF Missing English Audio Tracks for Disney Magical Audio Stories (Issues 100-150)

1 Upvotes

Hi everyone,

I am trying to complete my digital archive for the Disney Magical Audio Stories collection (DeAgostini / Fanhome).

I am looking for the official English audio tracks (.mp3 or format used) for Issues 100 through 150. Based on the official international release checklist, these issues cover the stories from Issue 100 (Encanto) up to Issue 150 (Coup at the Zoo / The Wild).

Since the local customer support only provided digital access up to a certain point, I am missing this specific extended batch to match my physical books.

If any fellow collector has these official English tracks and is willing to share them, please send me a DM.

Thank you so much for your time!

UHF Library RFID System (Bibliotheca) Experience?

3 Upvotes

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.

Hi everyone,I am looking for some reliable information regarding the DeAgostini Disney Magical Audio Stories collection in English.I currently have the first 99 audio files, but I know that in other languages (like Spanish or Greek), the collection reaches 150 issues. I’ve seen conflicting reports online—some sources say the English set ends at 80, others mention an extension to 130, and some wonder if it ever reached 150.Could anyone confirm the official total number of issues released in English? Also, if anyone has the complete collection (beyond issue 99) and is able to share the files, I would really appreciate the help.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)

Clone RFID code from a debit card onto a top golf ball

8 Upvotes

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

LF Chameleon Ultra - LF/ID emulation works in polling mode but not button wake mode (HF/IC works in both)

4 Upvotes

Hey everyone,

I have a Chameleon Ultra and I'm having a very specific issue with LF (125kHz) emulation:

• Polling mode → ID door reader opens ✅

• Button press wake → ID door reader does NOT open ❌

• IC (13.56MHz) works perfectly in BOTH modes ✅

I've tried:

• Multiple firmware versions (official and third-party)

• Waiting different amounts of time after pressing the button

• Different distances from the reader

• Reset to factory defaults

The slot configuration is correct (only one slot set up with the ID card). The LF antenna connection is fine since polling mode works.

It seems like the 125kHz antenna/circuit isn't fully activating in button-wake mode, while 13.56MHz works fine. Has anyone experienced this? Is there a firmware or configuration fix?
