Dual frequency RFID cards with a 13.56 MHz and 125 kHz chip
(Product ID: 1199)

Do you want to use a single key card for your 125 kHz access control system to a parking lot and your 13.56 MHz electronic lock?

Check out our dual frequency RFID cards with a combination of a TK4100 chip that operates at a frequency of 125 kHz and a F08 chip that operates at a frequency of 13.56 MHz.

These two microchips are very widespread proximity chips, and are used in countless applications worldwide.

The 125 kHz TK4100 chip is a read-only chip with a pre-programmed chip ID code, and the F08 chip is an ISO 14443 chip with a pre-programmed chip ID code and a memory size of 1 kB for storing transactions or other user data.

These dual frequency RFID cards are made from multiple layers of PVC and die-cut to a credit card dimension 86 x 54 x 0.85 mm. The top layer contains a coating and the cards are suitable for subsequent printing with all brands of card printers.

You can buy white cards from stock, or send us an inquiry for printed cards with your company logo, serial numbers, or other personalization.

When printing 1-500 cards we use high quality thermal re-transfer printers which can print single-sided or dual-sided artwork in CMYK colors.

When printing 500 cards or more, we use offset printing technology and print the cards during the manufacturing process.

These dual frequency RFID cards can be used to unlock the electronic locks, record attendance at work, and they can identify users in countless applications, no matter if the systems support the 125 kHz chips or the 13.56 MHz ISO 14443 chips.

A dual frequency card contains a combination of a TK4100 chip and a F08 chip.

The TK4100 RFID chip is a very popular 125 kHz read-only chip that works like the EM4200 and its predecessors the EM4100 and EM4102. It has a preprogrammed unique ID number which is used as a key identifier for access control systems and other identification purposes.

The F08 is an ISO 14443 chip, it has a preprogrammed 4-byte long unique ID number which is used as key identifier in various RFID systems operating at 13.56 MHz and a storage capacity of 1kB bytes for storing transaction details or other information.

Dual frequency RFID cards are bright white and made from multiple layers of PVC. They have a standard credit card dimension 86 x 54 x 0.85 mm and can be printed with various brands of card printers like Zebra, HID Fargo, Matica, Magicard, Datacard, Evolis, and others.

Printed RFID cards

When we print 1–500 cards, we usually use high quality thermal retransfer printers and the cards can be even personalized with color employee photos or the chip UID numbers.  

When we print 500 or more cards, we make a pre-print with offset printing technology and subsequent personalization with thermal printers. Offset printing technology is very cost effective for high quantities of cards, the disadvantage being that the process takes quite a long time (approx. 2 weeks).

If you need printed RFID cards, please send us an inquiry with the desired card quantity and deadline.

RFID cards with other chips

There are a lot of different RFID chips and they differ in operating frequency, the amount of memory, reading distance, supported protocols, additional protection, or other functionalities.

If you need the RFID card with another chip or a specific combination of chips, please send an inquiry.

The RFID chips we use the most are:
•    13.56 MHz: MIFARE Classic®, MIFARE DESFire®, NTAG, ICODE®, MIFARE Ultralight, Fudan F08, etc. 
•    125 kHz chips: EM4200, TK4100, T5577, etc. 
•    UHF chips: Alien Higgs 9, UCODE 8, etc. 

Reading test for Dual frequency RFID cards with 13.56 MHz and 125 kHz chip

We tested our dual frequency cards 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
SYRIS RD300-H1-G 6,5 cm
ACR1252U 6 cm
SYRIS RD200-M1 6 cm
R80C 5 cm
Promag PCR-330M-00 3 cm
125 kHz RFID reader R80D 2,5 cm
Syris RD200-LF 2 cm
Promag PCR-330A-00 125 kHz RFID Card Reader 1,5 cm

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.
