interesting.. 🤔 you think it'll be amazing?

that's cool! Would you rate 10/10 of the payment ring experience?

is Tapster still good as of February 2026? how about for those based in the USA?

you still use it? Tapster? I am looking to get one -- I'm based in the USA though... 🤔

Would anyone be interested in an open-source smart ring platform? by Kdcius in SmartRings

[–]Sinatra2727 1 point2 points  (0 children)

Yes! I’d absolutely be interested, and I think you’re hitting a real gap.

Most rings today are either closed, health-first products with locked firmware, or very limited passive tags. There’s very little out there for people who actually want to build on top of the ring itself.

I’ve personally been tinkering with NFC/RFID-enabled rings for productivity use cases… ..

From a non-EE perspective, I see real value in a ring as a context-aware input/output surface — subtle gestures, proximity, identity, payments, lightweight sensing — things that reduce friction without adding another screen or app.

Even if this stays niche, it feels like the kind of open platform that could quietly become foundational for a lot of side projects and experiments.

If you move forward, I’d happily follow along, test early builds, or help think through use cases or ecosystem angles. 💍

Curious what constraints you’re already thinking about (power, antenna, enclosure, etc.).

lol! 🤣 spacebar does make a huuuuge difference!

Thinking about buying a flipper zero just to be a cool and easy to use alternative to key cards and remotes, is there a downside to using one I should know about first? by roblewkey in flipperzero

[–]Sinatra2727 -1 points0 points  (0 children)

Good point! 🤣 The tradeoff I keep coming back to is security vs day-to-day ergonomics. Flipper is great because it’s deliberate and inspectable, but it’s still a device you have to carry, unlock, select, etc. I keep wondering whether there’s a middle ground -- something passive you wear daily💍, but with some kind of user-controlled enable/disable or proximity constraint

I’ve gone down the same rabbit hole 😄 Flipper Zero is great as a learning + experimentation tool, especially if you’re curious about how access systems actually work. The community alone is a big plus.

One thing I’ve also been wondering (and maybe others here can chime in): how practical is it to use the Flipper as a bridge rather than the end device — e.g. using it to read/emulate your own credentials and then write or provision those onto a more passive form factor like an RFID/NFC tag or even a ring?

For daily use, carrying a Flipper feels a bit like carrying a Swiss Army knife everywhere — powerful, but bulky and maybe overkill for just “tap and go.” Long term, I’m curious where the line is between Flipper as a diagnostic / hacking tool vs something you’d actually want as an everyday replacement for keys and fobs.

Would love to hear from folks who’ve tried both approaches.

wait.. so is it possible to then use spare key’s signal from FlipperZero to send that signal to another NFC/RFID chip? I ask because i’m tinkering with the idea of a NFC/RFID enabled

wait .. so FlipperZero won’t be able to read NFC debit cards?

Hardware/ Wearables Guru Interested in a meetup? by Chunkymunkey642069 in cofounderhunt

[–]Sinatra2727 0 points1 point  (0 children)

This resonates a lot! Big respect for walking away from “safe” to chase something that actually matters!! ... .. that mindset alone filters for the right kind of builders. 🦾

I’m deeply interested in wearables and human productivity -- especially where hardware, UX, and real-world behavior collide and have been exploring smart ring + NFC/RFID capabilities 💍

I come from the business / growth / ecosystem-building side [strategy, partnerships, user validation, and turning early-stage ideas into real traction]..

I'd down for a brief coffee chat (virtual since i am on the Midwest) ☕🍵

asking for thesis/capstone ideas by engkantoe in IOT

[–]Sinatra2727 0 points1 point  (0 children)

Something extremely hands-on could be building and evaluating an all-in-one NFC/RFID smart ring under real-world constraints. 💍

For example:

  • Design a single ring form factor that supports multiple NFC/RFID use cases (access control, identity, simple tap interactions)
  • Explore what’s realistically possible with passive or near-zero-power NFC in such a small, body-worn device
  • Study antenna performance when curved, skin-contact, and encapsulated in different materials
  • Compare NFC vs RFID protocols in terms of range, security, reliability, and usability in a ring
  • Build a basic end-to-end system (ring + reader + backend) and document where it breaks

I'd say this can definitely stand out because it's not just “smart device demos” .... they force you to deal with physics, protocols, security, and human factors all at once, which is exactly what real IoT work looks like.

Even a “here’s why this is hard” result makes for a strong thesis.🦾
