Dual frequency disc tag with a 125 kHz TK4100 chip and a NFC NTAG213 chip
(Product ID: 1695)

125 kHz & NFC
Are you looking for dual frequency transponders with a 125 kHz and an NFC chip inside a single tag?

Check out our dual frequency disc tag with a TK4100 chip that operates at a frequency of 125 kHz and a commonly-used NFC NTAG213 chip.

These 25 mm tags were designed for installation in various pendants or other products and are ideal for the identification of products made from non-metallic materials (plastic, wood, paper, leather, etc.)

Since they contain two of the most commonly used proximity chips, they work with the majority of 125 kHz readers and NFC readers.

The advantage of using these transponders is also that the combination of two chips allows us to identify the product even if one of the chips accidentally stops working.

The TK4100 chip is a read-only chip that operates at a frequency of 125 kHz. It has a pre-programmed chip ID number, and is used in countless applications worldwide.
The chip ID can be read with various 125 kHz RFID readers.

The NFC NTAG213 chip is an inexpensive NFC Type 2 chip which works according to the ISO/IEC 14443-3A standard. It has a preprogrammed 7-byte long unique identification number and a storage capacity of 144 bytes of data.
When working with NFC chips you can use various desktop readers or other NFC devices like mobile phones, tablets, etc.

You are welcome to purchase the dual frequency disc tags from stock or send us an inquiry for customized ones. We can customize the tag dimension and shape, we can print company logos or other information, etc.

INFO

Dual frequency disc tags contain two commonly used contactless chips and can be used with systems operating at different frequencies.

They are ideal for tracking various non-metallic products. They can withstand elevated temperatures for a short time and can be covered with pre-formed plastic.

The TK4100 RFID chip is a 125 kHz read-only chip that works similarly to the EM4200 and his predecessors, EM4100 and EM4102. It has a preprogrammed ID number which is used as an identifier in various RFID applications, and cannot be changed. The chip ID can be read with various 125 kHz RFID readers.


The NFC chips NTAG213 (NFC Type 2) are made by NXP Semiconductors and are the most common inexpensive chips, designed for mass market applications. They work according to the ISO/IEC 14443-3A standard, have a preprogrammed 7-byte long unique ID number and a memory of 144 bytes which is equal to a 136 character-long URL address or other text. 

The chip ID is always easily readable with many NFC readers or mobile devices, and is visible to the public. The ID is usually used as an identifier which connects the product to the other information inside the manufacturer database.  

The NFC chips memory can be programmed with regular NFC mobile phones (Android and newer iPhones) or desktop encoders. To program NFC tags with a mobile phone, you can use free applications like NFC Tools, NXP Tag Writer, and other NFC apps.

The chip encoding is quite simple. If you use an app NFC Tools you have to click ‘Add Record’ – select a feature you want to use, write your data, and click ‘Write.’

NFC Tools has many other useful features like ‘Copy tag,’ ‘Erase tag,’ ‘Lock tag,’ ‘Read memory,’ ‘Format memory,’ ‘Set password,’ ‘Remove password,’ and some other commands for advanced users.  

For a mass programming, we recommend using an encoder ACR1252U and software like the desktop version of NFC Tools.

The memory size of 144 bytes is enough for the following sample data: 

“ID: PRO123456789RE; Prod_Date:14.9.2021; Lot_No.:SD266543FT988G; Key_Parameters:19-A3-46-23-F3-67-94; Service_Date:12.7.2021; Status: OK” 

When writing custom data to an NFC chip, you may use your custom security key and the content will be hidden from non-authorized users.

The dual frequency disc tags can be used also for proof of ownership of various sporting equipment. The manufacturer can use the chips ID for manufacturing purposes and product tracking, the user can store and lock an ownership data like:

“This windsurf belongs to John Deep, 2803 Pike Street, San Diego, California, 92123, USA. If found, please call +1 858-597-5073.”

The combination of two chips allows you to identify the product even if one of the chips accidentally stops working.

The dual frequency tags by default do not contain any numeration or other printed elements or adhesive but if you need customization, please let us know and we will send you an offer.

Options for customization (for pricing, please send an inquiry)

Beside the dual frequency tags from stock, you can order the customized tags with the following features:
-    Custom size or shape,
-    Additional layer with adhesive,
-    Printed elements like the company logo, serial number, chip ID codes, etc.
-    Additional layer with on-metal protection 


Reading test for dual frequency key fobs

We tested our dual frequency key fobs with different kinds of readers and measured the reading distances. This is not an official test, but was made to inform you what reading distances you may expect with your application.
 
RFID reader  Reading distance
ACR1252U  
SYRIS RD300-H1-G  
SYRIS RD200-M1  
R80U  
SYRIS RD200-LF  
R80D  

The reading distance between the key fob and the reader is affected by many different factors, like the size of the antennas and quality of the chips, the interferences of metal, and electromagnetic signals, etc.
