In my DRAWER of bits, I also have one of these.
Never used it, never tried to use it.
I tried with a couple of fobs, (all I had handy) it APPEARED to read OK, but no go on the write.
As Amal said Rubbish
- I only tested on a HID Prox and EM410x
- Of those two, the cloner would only read EM410x
- I managed to read from EM410x fob but could not write to to another fob,
- I could write from the fob to a card
- I could not read nor write to a FlexEm ( Facsimile )
I may put the antenna on the outside and try again, But I think it will make very little difference.
