Any chance DT can/will carry the NFC OPN Ring or other NTAG216-only ring?
Thanks!
ntag216 only ring is what they’re looking for
aliexpress is flush with them
I had not seen the new website, looks sweet!
Not NTAG216-only
Link?

they’ve a BUNCH goin in them 2x 216 which is what you’re looking for.
does it 100% have to be ntag216 not 215 213 etc?
Not looking for expensive 6x with poor RF, just single 216.
Yes, 100% has to be 216-only.
why does it have to be ntag216?
Need >504bytes
The OPN ring is not ntag216 … but we will have a ring product shipping soon that has an Apex inside (Apex Platform – VivoKey Technologies) on which you can deploy an NFC container for NDEF data that is either 1k, 2k, 4k, 8, 16k, or even 32kB in size!
why not get the dangerous things mifare classic ring? it’s ndef formatable and has 720 user bytes
Not NFC-standard
interesting… the last i heard the OPN was supposed to be a developer ring with an infineon chip inside… huh. thanks for the datasheet.
we will be exploring rings with ntag216s inside but not anytime soon… maybe 6-9 months we might have something.
There’s definitely market desire for NTAG216-only ring – please reply here if/when available.
I hope/expect the market to bifurcate from current 213/215. For users only needing UID, URL, or single-contact vCard, 210/212 are enough. For advanced/pro, 216.
Yeah I don’t see a point in making anything less than an ntag216. Once a new product hits it’ll be posted to Can I join an email list or something? - DT Info - Dangerous Things Forum
