As we all know, if the two chips of D41+S50 are sealed by one card, it will not work normally, because D41 and S50 are high-frequency 13.56Mhz chips, and they will interfere with each other.

There are currently some solutions on the market. One is to adapt the card reader corresponding to the high frequency and adjust the frequency difference between the two chips to a larger value,
but the stability of this method is not strong. , More or less still will produce some interference.

So, do we really have no relatively stable way to make two chips of the same frequency work normally on one card at the same time?
The answer is: yes!

When some of our customers need to use the application environment where D41 and S50 are packaged in the same card at the same time, we can try this chip-FM D41+S50.
We have divided a chip EEPROM in D41 The space used for S50 work comes out, which is used to simulate the work content of S50, so as to realize the application that allows
the functions of two chips to work normally in one chip.

If there is a need for “same frequency chip package to the same card” customers, you can contact us for the most detailed solution. Welcome everyone to consult us, we promise
to use the most professional service to provide you with the latest RFID technology application solutions.
