Please note as with all MIFARE Classic® 1K tags these are NOT compatible with any mobiles that do not have the NXP read/write chip in them. Most USB readers are fine with these though.
These tags are perfect for automating large sets of tasks on your phone due to the larger storage space on them of 716 characters after NDEF formatting. We are shipping these already formatted so that they are compatible with Windows 8-10 phones that currently are unable to write to tags that are not formatted already.
We would NOT recommend the use of these for business purposes where you can not control the mobile phones being used with them, but for personal use or business where you know you will not be using a Blackberry or a Nexus 4 or 10 you will be fine. If these are not suitable for you then look at our NXP NTAG216 stickers that are compatible with all mobiles and you get 850+ characters.
These are 35mm round NFC = stickers The reading distance is very good on them. They are sticky on one side and have a strong white PVC backing with a slightly glossy finish.
Please note these are only meant to be used indoors and they will not work when placed on a metal surface.
