size of ring inlay tags
tried to write to the ring my contact card from my phone (address book) but received a reply that the smart tag is too small, what's the size of it. i had to write 509b of data
I believe they are they are Type 2. Type 2 tags typically store 48/144 bytes.
from the FAQ of the store:
Q What is the storage capacity of each inlay in the ring?
A 144 bytes, 1152 bits of awesomeness. 4,369,066 rings would be needed to fill a CD of 600MB
Q What’s the NFC tag inside the ring?
A We currently use the NXP NTAG203.
Just to expand on that a little, the maximum amount I could shove in there with a Nokia N9 was 132 bytes, the rest would have been the record type ie 'vcard:'
