Discussion Overview

The discussion revolves around the interpretation of a 6 pair hexadecimal number associated with an RFID/RFIC device, specifically what each pair represents. Participants explore the relationship between RFID, RFIC, and Bluetooth technology, as well as the identification and decoding of the hexadecimal number.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks clarification on what each pair of the 6 pair hexadecimal number represents in the context of RFID/RFIC.
  • Another participant questions how the phone is able to ping the RFID device, suggesting that it may not be possible unless it is a Bluetooth device.
  • A participant mentions that RFID is primarily for tracking and identification, while RFIC is used for telemetry, expressing interest in identifying the device's manufacturer and application.
  • One response suggests that the hexadecimal code could be a hash tag used as an index to a database rather than encoding actual information.
  • Another participant assumes the hexadecimal number refers to a MAC address, which is a unique identifier for the device, and provides a link for further information.
  • A later reply confirms that the hexadecimal number is indeed the MAC address and indicates that the participant was able to locate the manufacturer and address.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the hexadecimal number, with some suggesting it is a MAC address while others propose it may serve as a hash tag for database indexing. The discussion remains unresolved regarding the specific representation of each pair in the hexadecimal number.

Contextual Notes

There is uncertainty regarding the exact nature of the hexadecimal number and its relationship to RFID and RFIC technologies. Participants have not reached a consensus on the interpretation of the pairs.

Hi All,
I'm new to RFID/RFIC and I downloaded an reader app to my phone and identified a device with a manufacturer that I couldn't find anywhere online with a 6 pair hexadecimal number. Can anyone tell me what each pair represents?

Welcome to the PF.

How is your phone pinging the RFID device? Unless it's some Bluetooth device, I don't know how it can ping it.

Also, what research have you done so far into RFID and any standards that are in use? :smile:
 
The app states that it uses a bluetooth connection. I'm interested in both RFID and RFIC. For what I understand, RFID is used for tracking and identification. RFIC is used for telemetry and the such. That's really what I'm interested in. Firstly, identifying a device: i.e.. manufacturer, use, origin, application, format and so on would help greatly. I've been searching the net to try to locate how to decode the number and am hitting a wall. I did find an image on Google, unfortunately, I can't trace where I saw it. Again, simple question: What do the six pairs of hexadecimal numbers represent?
 
If you really retrieved the code, there is probably nothing to decide. It could be a hash tag used as an index to look up a database record. It doesn't make sense to encode the actual information into a RFID chip.
 
Any information on this device would be helpful. What do the pairs represent?
 
Your request is not very clear, I can only assume you are referring to the MAC address, which is the unique identifier of the device.

When describing bluetooth, it is not (at least in my experience) referred to as RFID, RFID is something totally different.

Yes, thank you for your reply. I'm a bit familiar with RFID and RFIC. I was simply stating the binging mechanism used by the app, Bluetooth. Thanks, it is the MAC address and I was able to locate the manufacture and address.
