My office users HID iCLASS SE readers for door access, they list compatibility with MIFARE / DESFire but can’t seem to read my xNT chip, not even to show an error state. My chip works fine on our samsung door locks, and can be read by my iphone and android phone just fine.
Is there some setup I’m missing to get it read by the HID units? is there a different chip that would be read by them. Our security folks are happy to clone my badge to my chip or allow me a second “badge” via my chip.
Do you have another NTAG216 type tag in card format that you can test with to see if it will produce any results?
Card readers that expect card format tags can have trouble reading x-series tags so position as well as orientation of the tag is super critical to get proper coupling. An HF xLED would help you greatly to determine the best way to present the xNT
I agree. Get the diagnostic card and hold it up to the reader. That’ll give a pretty definitive statement as to whether or not it’s 125k or 13.56. I’ve personally seen and installed HID multiClass readers that do both the old 125k style and newer 13.56. It’s very possible your installer just put them in for forwards compatibility - although they look like iClass they bear a different nameplate. Could be a weird fluke or not, who knows. Most likely the reader is just getting what it thinks as garbled data and refusing to read - like when you scan an EM card on an HID reader, nothing happens. There’s also a small possibility that the reader is programmed to not even make any outwards signs that it read an invalid card although that’s unlikely unless you’re in some crazy secure facility with 3-letter agencies.
Bottom line, get a diagnostic card. They’re cheap and work for way more than just this.
Unfortunately our badges are very custom and do not have any markings that would explain anything about its technology or standards. I’m 100% sure that the USB reader i linked to is the correct one (as its the one that we can request from our internal hardware store) but I do know that our physical security does flash/configure the device with some sort of custom setup before they’re usable.
I’ll order the diagnostic card and see if I can learn anything from that. Physical Security isn’t willing to give me any details about the badges or readers only to allow me to clone my existing badge if I can provide a compatible proxy for our badge.
If you can read your work badge with your android phone it is almost 100% likely to be 13.56Mhz.
Does TagInfo give you any details about the type of chip it is seeing when you scan it with your phone? I’m wondering it the HID iClass reader just reads the UUID or if it does anything else (such as read/interact with the card)
This sounds like your work badge is a 125khz card then. If your phone isn’t getting anything from it, then it very likely is an RFID badge not NFC. I personally have an xEM and xNT, and use my xEM for scanning in at work. For me I cloned my work badge using one of those “10 Frequency RFID Cloner” machines, though people have had success with the cheap blue HID Cloners you can get on Amazon. Getting one of the DT RFID diagnostic cards which will tell you 100% whether the readers you have at work are 13.56mhz or 125khz is what I would do as a first step before investing in another implant.
You’re going to need an xEM. Depending on the reader’s config you’re looking at (most likely) HID Proxcard, or (less likely but possible) Indala or EM. All can be done with the xEM (not xNT). Due to the unknown nature of what you’re working with I’d suggest a Proxmark just to make your life a bit easier when it comes down to cloning it. If I were you I’d just go and have security program a new “badge” using the chip instead of cloning as this gives better security. Just generate a random facility code and card code and securely give those to security.
