I did some research and found that these types of tags will work for simple phone automation tasks however, the task that I setup was a complex URL which will not work. Will be ordering some NTAG203 tags and will report back. Quick question, are the samsung tectiles NTAG203?
I stayed up way to late last night learning about NFC tags.. so NXP use to make all NFC hardware for phones, and they came out with the MiFare 1ks.. but they were proprietary.
Then when BroadCom made some NFC hardware for phones, they just used what the NFC specs were, which were the NTAG203s (they don't have a lot of memory, 130bytes or so) Topaz 512, and I read that the MiFare 4ks are also compatible.
Samsung's site identifies Tectiles as MiFare 1k. TecTiles 2 I think are, but I can not really find them or any info on them.
My 4ks were expensive, but I will let you know soon if they work.
