Again, apologies.
Just to clarify for you.
The TagInfo App, is for Scanning and Identifying the chips in Tags, fobs, cards etc.
(High Frequency only)
The Diagnosic card you would use to identify if your reader is High Frequency or Low Frequency.
DT sell these but with most purchases you will get one of these included.
Anyway, back to your results
That is potentially good news.
To me I would guess that is Low Frequency.
The T5577 chip is a fantastic chip, it is in almost all of the LF implants.
So this is looking like it is HF.
(I have scanned one a while ago, and from memory it was a mifare 1k)
Could you try again following this video
We are getting close to an answer.
That will be awesome when it comes time for install…
