@Hellsy 125kHz rfid is quite different to 13.56MHz NFC. There would be major tuning issues at the very least, and if possible at all then there'd be an age worth of R&D before it were a reality. You can't just build on the back of what has currently been done, you throw it all out the window and start again.
The "timer 2" ring appears to be no more or less a cheap, rushed knockoff than any of the others we've seen. Larger read distance will be a function of IC type and metal density. Think cheap.
To look back to your first post, since you're all full of sarcasm and misunderstanding;
"Mifare Ultralight is unsecure. Yes-yes, you cut the 2/3 of antenna and now a lot of nfc-phones cant detect a ring and all other require a long search of the "sweet spot", but it's not a solution."
The antenna on the NTAG203 inlays that John uses is a custom design, correctly tuned to function consistently while inside a titanium shell. That's an achievement that doesn't deserve to be shrugged aside like that, it takes time money and a lot of effort to do these things. As to the NFC phones, it's not a lot that have issues. As with everything, you tend to hear the complaints more than the silence of satisfaction. Just because you hear complaints doesn't mean everything is ruined... it just means that sometimes, poorly built and badly designed phones are failing to read rings when their design problems are exacerbated by wear and tear in use.
The solution is up to the phone manufacturers, not the accessory manufacturers, yes-yes.
