Are there any plans to do a LF ring from a t5577 chip? Asking for someone that’s not quite onboard with getting an implant, I might convince them though.

We used to have these in stock but they were not great sellers. You can easily get a T5577 chip based card from Amazon or other retailers if you want to test things.
So this is exactly what I did. I 3D printed a ring out of TPU and embedded the xEM chip inside of it. Writing to the chip was challenging but the ring worked great once programmed. The TPU feels very similar to the silicon rings that are available now.
