If (big if), you just barely crossed into an area with enough magnetic coupling (as you moved your hand into the field), it might make a difference whether you needed that extra distance to be close enough.
Yeah, it could make a difference, but it is a big if and shouldn’t even come into play if you are placing the chip flat and perpendicular to the antenna generating the field, as the chip should be sitting level under your skin.
This is just begging for an RGB LED driven by the chip, programmable with some custom APDU command, either to choose the color, cycle through different colors, or show what the chip is doing (e.g. blue when it’s receiving a carrier, green when it’s been read, red when it’s been written to…)
Of course, it’s not as simple as soldering a LED in parallel
Yes… they were all supposed to be loaded so the LED would come out of the needle first… but the ones we did lot testing on were loaded backwards… so the coil came out first… but then we had a customer plan a placement with that information and it appears the LED side came out first… which really annoys me greatly. I’ve already chewed an ear off of someone at our contracted assembly factory… so it appears “most” of them are loaded such that the coil comes out first.
If the prices ever align I might get one of these in green, cause that’s about as close to being a drone as I’d ever wanna get, lol. It’s just not worth a $70 bump to me. I also have to figure out if it’ll be worth it down the road over a NExT for what I’ll use it for.
