thanks! I read your bio and links, all very informative, and definitely got me thinking about the payment implants, will be researching those some more... very cool (but maybe a little spendy as a starting point). RFID/NFC (& of course gotta have a LED) seems a good place to start & I would like to have rfid for the EMF bar tills before 2028 (plenty of time, maybe... time flies.)
There are so many options on Dangerous Things that its a tad overwhelming. (I do know a bit, but not a lot, about RFID/NFC and have used both in my own projects before.)
I like the idea of the glow in the dark stuff too. (I am presently still enjoying my glow in dark fingernails I did for EMF, even at my age I am still weirdly amused by glowing things 😅)
