I bought this little lock.
It looked nice for useing to lock drawers.
I was able to activate it with the Classic 1 card I had.
Works perfect.
It also seems to respond reasonably well to the keychain chip. It blinks…
but to an implant? Nothing … not even after I disassembled and pressed the antenna to the skin.
Could it be that if we replace it with a deferent antenna it will work better?
Anyone have experience with these locks?
Often,battery operated readers use battery saving techniques that keep the reader mostly off and in a low power until a tag is detected in the field…and many times full size cards work fine to wake up the reader, but the x series tags are too small to trigger the “wakeup” detection.
That doesn’t mean much… Put the led on it then put the card that works in the field, see if you see any difference in brightness when the card comes into the field.,
Making an antenna is not easy… not impossible but its much more complex than wrapping some wire around a coil.
I hope Someone can summarise this super smart technical guide on how to design antennas for nfc chips, into 5 short lines for me?
I cant make any conclusions out of it.
Okay so what I’m getting at here is the chip inside the next implant is not the same chip as the cards used by the lock. They are both ISO14443a protocol, but they are different chips with different memory structures and different ID length. It is possible that the lock is not compatible with the next implant.
Are you attempting to read the chips through the plastic case or have you tested in the same way that was done with the xFD keychain? What I mean is, have you tried to scan your xM1 directly against the antenna PCB in a perpendicular fashion?
Since the field detector seemed to have no problem getting power from the antenna… I’m wondering if there is some other problem. Can you scan your xM1 implant with your phone and NFC tools to confirm it is still functional?
