Any RFID (13.56) experts??
-
Hi, The company I work for is using 13.56MHz RFID for a project. This project involves reading a tag and playing an audio track. I got a third party reader and could read the Tag UID fine but miss the 'extra' data embedded in the read/write section of the tag. Issue is I did my 13.56 Tag training at Texas Instruments and there was no mention of R/W sections of the tag, only an encrypted data section (used at the time for GasN'Go in Canada) so what I'm wondering has the spec changed or have we go a product using a protected area of the tag?

Some docs on types Common RFID Standards and Protocols You Must Know - Xinyetong[^] From that and your post then the spec is 18003. That seems to be this spec which you would need to buy ISO/IEC 18000-3:2010 - Information technology — Radio frequency identification for item management — Part 3: Parameters for air interface communications at 13,56 MHz[^] As I read your post it is not clear to me if you think the RFID has the audio track or if it is just used to initiate the play of a track which is stored elsewhere. The following suggests that only the later it possible. Juuke - a RFID Music Player for Elderly and Kids : 10 Steps (with Pictures) - Instructables[^]

Thanks, I was thinking read back the UID, UID links to Audio track in the reader, plays audio track. I am not sure if this is the approach or not (I hope so). There does seem to be an issue with life of the batteries which indicates to me the RF Unit is being left on for too long. This then leads to why? I can power a reader than reads the UID from a low capacity power bank with no issues. From what I remember of the 13.56 training I did was there was a read only section that could only be read by a special reader which was developed and used on the Canadian GasN'Go system... Could we be possibly be using a 'protected' area of the card meaning some readers won't read all the data (other than the UID)... I will have read of the spec's you provide and hopefully have an answer..:~

Huh? Obviously you did not provide the full specification. There are musical devices that use RFID for control but those should have a fixed supply. I was thinking maybe they wanted a security beep for each valid RFID and something else if invalid (or other states). But again should be fixed supply. Perhaps a portable service reader and the beep indicates that it was read, successful or not. But then plans must be made for recharging or changing batteries (presumably rechargeables.) But really none of that has anything to do with the RFID but rather with the design and engineering of the system/product.
