Went to DSE after lunch and found this deal, 5 Sasmung TecTiles NFC tags for $1. I went to the Glen store in VIC, they have around 5 packs in stock. (I took three while I was taking the picture, after that I realized it isn't compatible with Galaxy SIV then I put them back).
This tag uses a MIFARE classic chipset, it only works with phones have NXP controller on-board. This tag IS NOT compatible with most of the recent phones / tablets. It is compatible with Samsung Galaxy SIII and Note II. I believe it is also compatible with whatever phone has a NXP NFC controller.
BTW, I believe 5 Tags are enough (three for home, one for office and one for car). 20 tags pack is a over-kill, I still have 15 sitting in my draw…
For these devices need a NTAG203 tag (Galaxy SIV, Nexus 4, Nexus 7 etc), please wait for the Samsung TecTiles 2 or here are the teleports to the right deal, (both were expired, just give examples for the right product)

Yeah it used to be $5 for five I think - there was a comment in one of the DSE posts. I'm just waiting for another NTAG203 deal just not 1 per person!
