[solved] Unable to read Adafruit 1482 1K

I've been trying to read this tag without any luck. From the website description it seems to just be a Mifare Classic 1K. It's listed as a Mifare Classic on Amazon   

Right now I'm using an ACR122U on a kali virtual machine. I can use "nfc-list" to read regular Mifare Classic 1K cards, but I get an error (~unable to open, will update with exact message) when trying to read the Adafruit fob. Does anyone have any experience with this tag? Or know what I could try? Will a Proxmark 3 be able to read it? Thank you.

I'll order one and take a look, can you use MFOC against it?

Oh wow, appreciate that so much! Thanks. Will try mfoc later today. Would it make sense for nfc-list not to see the fob, but mfoc to see it?

I tried nfc-list on an actual machine now, as opposed to a VM and I no longer get any errors, but it's as if I ran the command without any rfid fob on the reader. It does nothing...

Tried running "mfoc -O fob.mfd" on the Adafruit 1482. The output was not good sad: "mfoc: ERROR: No tag found."

I wonder what's going on...

Chip should be delivered tomorrow.  It was dispatched from www.rapidonline.com yesterday afternoon so I will take a look at it and come back ASAP.

Re: [solved] Unable to read Adafruit 1482 1K

Thanks so much Onisan!

I feel a little dumb. I think I know why I was not able to read the fob. I thought I had an AdaFruit 1482, but in reality I think it was a leather EM4100 like the one here. I'm sorry you purchased the Adafruit tag. I bought one myself and was able to read it with the ACR122 without any issues. I however cannot read the original tag because it's likely 145khz / EM4100. I already purchased a proxmark3 from China.

I'm fairly confident I'll be able to clone the leather tag with the PM3, but this won't arrive in the mail anytime soon. Does anyone have a recommendation on the easiest / cheapest writer/reader that can clone EM4100s and ships from North America? I'd rather not have to wait until I get the PM3 from China. I want to copy the EM4100 onto a T5577. This seems like a very cheap option that doesn't require a computer, but it is also in Asia. This might also work, but I don't like that it's Windows only. I'd like to use something libnfc-compatible, but that seems only compatible with 13.56MHz? Any recommendations?

Trying to keep threads clean and on subject.  Do please start a new thread regarding buying a em cloner.

@OP, also edit the first post and add [solved] to the beginning of your subject.
