This package includes all of the best selling NFC tags and is great for experimenting with different types of tags! It comes with all the same tags as the starter kit, but we've added our new Mifare Classic 4K stickers to the mix. These tags are great for just about any task, boasting 4,000 bytes of memory! Other tags included: Mifare Ultralight (64 bytes), MIfare Ultralight C (192 byes), and the Mifare Classic 1L (1,000 bytes). Near Field Communication is an increasingly popular technology that will change the way we use our smart phones. With NFC enabled phones you can open URL, Enable/Disable/Toggle WiFi & Bluetooth, Launch apps, Change ringer options and More all by simply swiping your phone over an NFC tag! Unlike QR Codes, NFC doesn't require you to open an app or line anything up, you just have to be within 4cm of an NFC Tag and the phone automatically does the rest. Google, as well as several other big companies, are even looking to use mobile payments with Near Field Communication.
