Adhesive Ferrite for Anti-Metal NFC tags

If you try to attach an NFC sticker to the back of your iPhone or put a NFC tag on the metal peripheral, you’ve probably noticed that the tag will no longer scan. Even if the NFC tag isn’t directly on metal, just being close to metal is sometimes enough to cause your scan performance to take a dramatic turn for the worst. how you can make your tags work again ?

Even if the NFC tag isn’t directly on metal, just being close to metal is sometimes enough to cause your scan performance to take a dramatic turn for the worst. how you can make your tags work again ?


First we should to know why it happed ?


Simply, eddy currents are killing your tag performance. When an NFC reader is attempting to interact with a NFC tag, it produces a radio-frequency electromagnetic field that both powers the NFC tag as well as allowing the reader to communicate with it. When the NFC tag is affixed to a surface that is not electrically conductive, this process works very well and you get the smooth tag reading performance you expect.


However, something very different happens with the surface is electrically conductive. When a conductive material is placed inside a changing electromagnetic field, a current is induced in the conductor - these currents are called eddy currents. When these eddy currents form, they interfere with the reader and NFC tag’s ability to communicate with each other, resulting in a tag that seems to be unreadable.


In order to restore tag communication, D.O RFID Tag manufacturer developed a new material for the NFC tag. we use a special iron-containing ceramic material called ferrite. When a sheet of ferrite is placed between the NFC tag and the metal surface, it reduces the interferenced caused by the surface, allowing us to create a tag that can be affixed to metal structures while still being readable.


Would you like to get this specail NFC tags ?


There are two ways to get these ferrite backed “anti-metal” NFC tags - the most common is to purchase a NFC tag with the ferrite layer already included, although it is also possible to purchase adhesive ferrite “stickers” seperately and combine them when you apply the tag. While just about any tag can be made into an anti-metal tag, due to their specialized nature, they’re often only readily available in a handful of form factors with just a couple of different types of NFC chips. However, if you place a custom tag order with D.O RFID TAG Manufacturer, we can provide anti-metal tags with just about any combination of chip, form factor, and custom printing that you may need.
