RFID fob encrypted?

IF you are dealing with LF and Mifare 1K, your “best” may well be the FlexMT, The Range is fantastic so your coupling shouldn’t cause you any issues.
I had one, but did not install it.
I didn’t want it on the back of my hand, and I felt it was too large for my girly wrists.
I would reccomend you cut out a template
“33mm total diameter” to see how you would feel about it.
Maybe cut it out of a very flexible plastic, and stick it to your hand / wrist for a few days.

In saying all that, I would also say as you are a doctor, you will be aware of the risks installing this on the back of you hand, and your hands are you job!!!

An xSeries in your thenar space ( What we call #0 ) of each hand ( or the same hand depending on implants) will do minimal disruption for a shorter period of time…
The sacrifice would be reduced range on your readers.

If you went xSeries route an example would be
Left hand NExT for your Work access
Right Hand xM1 for home
(or the other way around)

OR

In either Left OR Right
xM1 and xEM
