ISO14443 RFID Passive Tags / Paper nfc chip sticker For Mobile Payment

ISO14443 RFID Passive Tags / Paper nfc chip sticker For Mobile Payment

   NFC Sticker tags communicate using the ISO 14443 type A and B wireless standards, which is the international standard for contactless smart cards, used on many public transportation systems. This is why NFC devices can be used with existing contactless technologies, such as card payment points. NFC Technology is pretty common now and features in most high-end smartphones. As well as phone to phone communication, small little NFC sticker tags can also be used to store and transfer informations. It’s a fast and efficient way to quickly push informations to your phone and these little sticker tags can replace barcode and QR codes, and could even be used instead of Bluetooth in some cases.

How to NFC stickers work?

   NFC sticker tags are passive devices, which means that they operate without a power supply of their own and are reliant on an active device to come into range before they are activated. The trade-off here is that these devices can’t really do any processing of their own, instead they are simply used to transfer information to an active device, such as a smartphone. In order to power these NFC sticker tags, electromagnetic induction is used to create a current in the passive device. We won’t get too technical on this, but the basic principle is that coils of wire can be used to produce electromagnetic waves, which can then be picked up and turned back into current by a another coil of wire. This is very similar to the techniques used for wireless charging technologies, albeit much less powerful.

  The active devices, such as your smartphone, are responsible for generating the magnetic field. This is done with a simple coil of wire, which produces magnetic fields perpendicular to the flow of the alternating current in the wire. The strength of the magnetic field can be adjusted by varying the number of turns in the wire coil, or increasing the current flowing through the wire. However, more current obviously requires more energy, and very high power requirements would not be desirable for use in battery powered mobile technologies. Hence why NFC operates over just a few inches, rather than the many meters that we’re used to with other types of wireless communication.

  The passive device works in the same way, just in reverse. Once the passive device is in range of the active device’s magnetic field, the electrons in the receiving coil of wire begin to produce a current that matches that in the transmitting smartphone. There is always some power lost during transmission through the air, but over short distances the current generated is enough to power the circuitry in the NFC sticker tag.These circuits are fine tuned to a certain frequency, which increases the device’s sensitivity to charging frequencies. This allows for a maximum transfer of energy across the air. Once the sticker tag is powered up, it can sync up and send data over the 13.56MHz NFC transmission frequency, just like your regular NFC communication between phones or other larger devices.
