Request for 134kHz reading #1077

Closed cshock159 closed 2 years ago

cshock159 commented 2 years ago

Request to add 134 kHz reading capability. The goal is to be able to read and decipher rfid chips injected into pets. The first half of pets/animals/livestock are covered with the 125 kHz reading, but due to https://en.wikipedia.org/wiki/ISO_11784_and_ISO_11785, there is some variation and 134 kHz would need to be added.

https://prckc.org/wp-content/uploads/microchipping-101.pdf more details on the methods of injection, the placement, and the reading of these chips.

FYI: http://www.gizmolab.co.za/fdx-b-protocol/

FDX-B, is an Animal Identification data format covered by ISO 11784/5 and normally operates at 134.2 KHz, which is slightly higher then the 125KHz RFID tags. It uses ASK modulation with BI-Phase encoding.

There is also the specs of the 128-bit stream.

This repo has ESP32 FDX-B code: https://github.com/s60sc/ESP32_RFID_Reader

As someone who rescues lost pets on the regular, this would be exceptionally useful. Please make this a reality. Thank you.

ghost commented 2 years ago

Same here. An ability to help with reading pet chips would be super usable, and saves a lot of time compared to taking them to the vet.

decidedlygray commented 2 years ago

As a newbie to the project, I was wondering if someone might be able to outline in broad strokes what would be required to implement this?

gorodulin commented 2 years ago

I have two suspicious looking stray cats in my backyard. They will bite if I try to catch them, but I could scan them to see if they are lost. Local RFIDs operate on 134.2 KHz

spencerthayer commented 2 years ago

I've more or less stopped using Flipper, but if and when this gets put into the code repository I'll finally have a use for it.

Bertus-W commented 2 years ago

it's being implemented by @DrZlo13 atm

exussum12 commented 2 years ago

Just tried the dev branch for this and it scans well! Great job @DrZlo13 and others involved

can you share which specific branch?

This would be a great win considering when my cat had a chip injected i was then told that I needed to "register" with some payment service to be able to identify my pet in the future. I'd like to cut out the middle man, my cat has a chip in it.... I should be able to read it just like anyone else should be able to read it.

exussum12 commented 2 years ago

The other service is still needed. The chip gives a number out. The number to pet info lookup is provided by a service similar to the one you are talking about.

databonanza commented 2 years ago

@exussum12 - wouldn't we just make a public registry? I don't see why you'd have to pay a service to do this. Enable the public to scan their own pets, provide a way for them to publicly register the numbers/contact info. Seems like the right thing to do vs. catering to a private "for pay" registry.

decidedlygray commented 2 years ago

Couple issues with that I think:

More info: https://www.aaha.org/your-pet/pet-microchip-lookup/microchip-search/

Kind of like registering a domain name. There are lots of different registries, and someone has to maintain WHOIS records and pay ICANN fees and whatever

databonanza commented 2 years ago

I'm not sure I follow. Github seems pretty free to me. Why couldn't a repo here do the job? I'm not attempting to be sly here, I'm just wondering why a paid service would be needed at all. Yes "someone" pays for github.com to stay online, but it's not you or me.

phptanker commented 2 years ago

I don't really care about being able to read from any pet database. I just want to scan my cat's RFID chips so I can make cool automations, for example count how many times they visit the bathroom box every day.

exussum12 commented 2 years ago

@databonanza time is not free either. Hosting on GitHub would mean managing pull requests.

exussum12 commented 2 years ago

@phptanker this current version wouldn't work well. While I can scan my dog it's not trivial to find. I think you would have better luck with a dedicated scanner

SnowLeopard71 commented 2 years ago

I needed to "register" with some payment service to be able to identify my pet in the future.

@databonanza Weren't you referred to a specific service to register with? Normally, the registration fee is included in the cost of the chip and you don't have to pay extra.

exussum12 commented 2 years ago

I know I did not pay for it originally, but to change my info (when moving house) I had to pay a registration fee of £15 from memory.

Preaching to the choir.

Yes, they wanted some yearly fee, it was like a subscription service. I think a "free service" could easily be made w/ private donations. If I were a multimillionaire I would gladly fund something like this out of pocket for the betterment of man.

ender003 commented 2 years ago

To add to the request - please also include the ability to read/emulate ISO17785 HDX half-duplex.

exussum12 commented 2 years ago

This can be closed now, it was added in the latest stable firmware

Taby1993 commented 2 years ago

Can flipper change number microchip?

skotopes commented 2 years ago

Check latest release and if you found unsupported tag then please report exact vendor/model

Taby1993 commented 2 years ago

Just this question, Can he change the number on the chip? Please answer to me.

Depends on what chip is used: if it is t5577 then yes.

Taby1993 commented 2 years ago

Fdx B iso 11784/5 134.2 Khz?

DrZlo13 commented 2 years ago

Our RFID scheme is not designed to receive HDX protocol. The rest protocols (FDX-A, FDX-B) mentioned in this issue is done.

Taby1993 commented 2 years ago

Ok thanks
