Yeah, it is.
Some phones will do mostly low power pulses followed by a higher power pulse.
@ItaBeAight I believe ws just suggesting you use an NFC app, to make sure the NFC is “reading” with High power.
Just to confirm, you have a High Frequency xLED?
if so
What phone do you have?
Does it have NFC?
If it does, Just make sure your phone has NFC enabled, and you should light right up.
Check out this list of phones, If yours is in there there maybe some clues as to the best placement.
iPhones are along the top edge.
Just be aware, if you implanted today, the swelling may make it more difficult to light up
If you have a low Frequency xLED,
you will need a “special” reader, for example, a LF access reader or proxmark etc
