Hi,
I am interested in access control by rfid modules and cards. But i have some doubts about it.
What i need is:
-R/W RFID module
-Reader RFID module
-R/W RFID cards

My doubts:

  1. Which is de diferent to use 13.56Mhz RFID module and 125Khz RFID module
  2. I saw in seedstudio that is only possible to find a r/w 13.56Mhz rfid module(RFR105A1M). is It posbile to find/buy in your web a r/w 125Khz rfid module?
  3. If i use a r/w 13.56Mhz RFID module(RFR105A1M) to write rfid cards. Can i use r/w 125Khz RFID Cards for it ?
  4. Can I use a reader 125Khz RFID module(ELB149C5M) to read r/w 13.56Mhz RFID cards?
    r/w = read/write

Thanks for all. Regards

Hi,

The datarate of 13.56Mhz RFID module could be much higher than 125K one. For more, google… :smiley:

Not yet, we only have 125khz rfid reader.

    No, they could only be used in pair.

  2. Can I use a reader 125Khz RFID module(ELB149C5M) to read r/w 13.56Mhz RFID cards?

No, they could only be used in pair.
