Mifare 4K NFC Tags for Galaxy Nexus, Nexus S, Nexus 7 (5 Tags)

This listing is for a package of 5 Mifare Classic 4K NFC tags. The tags come as a 30mm PVC disc tag with an adhesive backing. The tags are approximately the same thickness as a credit card. The Mifare Classic 4K chip holds 4kB of data, with approximately 3,331 bytes of writable space (after formatting). The Mifare Classic 4K NFC inlays use an NXP specific security protocol. Since these tags are plastic, they will work outdoors but the adhesive is not guaranteed to stick with weathering. NFC chip is waterproof. ** If you are purchasing NFC tags for a newer NFC enabled device, such as the Galaxy S4, Nexus 4 or 10, please purchase our "NTAG203 NFC Tags" here - http://goo.gl/D8Ulk. Mifare Classic tags are deprecated and will not work with these devices.
