Custom Anti-Metal NFC Tags

NFC tags are small stickers or labels that can store and transmit data wirelessly using near-field communication (NFC) technology. They are widely used for various purposes, such as marketing, authentication, payment, and smart home. However, not all NFC tags are created equal. Some NFC tags cannot work on metal surfaces, as metal interferes with the NFC signal and prevents the tag from being read by an NFC reader device. This is where anti-metal NFC tags come in handy. In this article, we will explain what custom anti-metal NFC tags are, how they work, and how you can use them for your business or personal needs.

What are anti-metal NFC tags?

anti-metal NFC tags are specialized NFC tags that can be read from metal surfaces, such as metal products, metal equipment, metal furniture, and metal vehicles. Unlike ordinary NFC tags, anti-metal NFC tags have a layer of ferrite behind the NFC chip. Ferrite is a material that reduces the interference caused by metal and allows the NFC signal to pass through. anti-metal NFC tags can also be customized according to your preferences, such as shape, size, color, printing, engraving, and encoding. You can choose from different options to create your own unique and functional NFC tags that suit your needs.

How do custom anti-metal NFC tags work?

anti-metal NFC tags work the same way as regular NFC tags, except that they can be used on metal surfaces. To use them, you need an NFC reader device, such as a smartphone with an NFC app. When you bring your NFC reader device close to the custom anti-metal NFC tag (usually within a few centimeters), the tag will be powered by the electromagnetic field generated by the reader device and send its data to the reader device. Depending on how you encoded your custom anti-metal NFC tag, it can perform different actions when scanned by an NFC reader device, such as opening a website, sending a text message, dialing a phone number, or launching an app.

How to use custom anti-metal NFC tags for your business or personal needs?

Custom anti-metal NFC tags have many applications for both business and personal use cases. Here are some examples of how you can use them:

– Asset tracking: You can use custom anti-metal NFC tags to track and manage your assets, such as tools, machines, vehicles, and inventory. You can encode each tag with a unique ID number or URL that links to a database or web page with more information about the asset. This way, you can easily identify and locate your assets by scanning the tag with your smartphone or tablet.
– Identification of metal products: You can use custom anti-metal NFC tags to identify and label your metal products, such as jewelry, accessories, appliances, and electronics. You can encode each tag with a product name, description, price, warranty, or any other information you want to share with your customers or users. This way, you can enhance your customer service and brand awareness by providing more value and information to your customers or users.
– Data transmission in metal environments: You can use custom anti-metal NFC tags to transmit data in metal environments, such as factories, warehouses, workshops, and offices. You can encode each tag with a command or instruction that triggers a specific action on an NFC reader device or another connected device. For example, you can use a custom anti-metal NFC tag to turn on or off a machine, adjust the temperature or lighting of a room, or send an alert or notification to a colleague or supervisor.

How do I test if my anti-metal NFC tags are working properly?

To test if your custom anti-metal NFC tags are working properly, you can use an NFC reader device, such as a smartphone with an NFC app, to scan the tags and see if they perform the expected actions. For example, if you encoded a web address to your tag, you can scan it with your phone and see if it opens the website in your browser.

However, before you test your custom anti-metal NFC tags, you need to make sure that they are placed on a metal surface, as that is the intended use case for anti-metal NFC tags. If you place them on a non-metal surface, they may not work as well or at all. This is because anti-metal NFC tags have a layer of ferrite, an anti-metal substance that protects the NFC chip from the interference caused by the metal surface. If there is no metal surface, the ferrite layer may block or weaken the NFC signal instead.

If you don’t have a metal surface to test your tags on, you can use a material that simulates a metal surface, such as a wireless charging power coil or an EMI anti-interference shield. You can stick your tag on these materials and then scan them with your NFC reader device.

I hope this helps you test your anti-metal NFC tags and verify their functionality. If you have any questions or feedbacks, please let me know.

Dimensions of the custom anti-metal NFC tags

The size of the aniti-metal NFC tag is customizable, without any extra fee.
The size can be chosen in a range between a minimum of 25 mm (diameter or side) and a maximum of 90 x 60 mm.
In any case, the ferrite substrate has a diameter of 20mm and is placed in the middle of the custom aniti-metal NFC tag.
The logo (or the graphics sent) is printed in a centered position on the label considering the chosen dimensions.
For specific shapes, you must send us a file with the cutting line exported as a vector path.
Print file
For the best result, a vector PDF file is highly recommended. If a vector file is not available, JPG and PNG file with high resolution (at least 300 DPI) are also acceptable.

The print file must have at least 2 mm bleed all around.

For example:

for custom aniti-metal NFC tag with a diameter of 39 mm, the graphics must have a diameter of 43 mm;
for 50 x 50 mm labels, graphics must be 54 x 54 mm in size.
If you want to print completely different subject, you must purchase the graphic changes. The minimum printable quantity for each subject is 10 pieces.

For particular shapes, it is necessary to send a file with the cutting line as well. In that case, please contact us.

Variable Printing for custom aniti-metal NFC tag
We print variable field with no extra cost, such as: variable text, QR code, bar codes, serial or progressive number.

In order to do this, you must send us:

an Excel file with a column for each variable field and a row for each label to be printed;
indications on how the various fields should be positioned (the ideal is with an example image complete with all fields);
information on any preferences for font, size and formatting of the text.

Optional chips include:
