Can NFC read 125KHz?
You cannot read a passive 125 KHz Tag with a NFC reader, because as you have already guessed, they operate on different frequencies. There are passive RFID cards operating on 13.56 MHz, however, and these will read just fine on a NFC-enabled phone.
Can RFID reader read any tag?
Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one from another.
Can you use NFC to read RFID?
7 Answers. NFC enabled phones can ONLY read NFC and passive high frequency RFID (HF-RFID). These must be read at an extremely close range, typically a few centimeters. For longer range or any other type of RFID/active RFID, you must use an external reader for handling them with mobile devices.
Is there a reader that can read 125khz tags?
You are correct NFC is 13.56MHz the key chain ones you are referring to are most likely 125kHz The reader you have will only read 13.56MHz this is the NFC and HID cards. If you want to read the Key Chain ones you will need a reader like this one. Weigand 26 Card Reader Most Phones will not read the 125kHz
Frequencies that are often used in access control are (examples in brackets): LF: 120-1355 kHz (HID Prox, EM, Nedap NeXS) HF: 13.56 MHz – (MIFARE Classic, DESfire, HID iCLASS, Legic) UHF: 860 – 980 MHz (RAIN RFID/EPC Gen 2) Microwave: 2.45 GHz and > (Nedap TRANSIT)
Which is 125khz or 13.56Mhz in NFC?
You are correct NFC is 13.56MHz the key chain ones you are referring to are most likely 125kHz The reader you have will only read 13.56MHz this is the NFC and HID cards. If you want to read the Key Chain ones you will need a reader like this one.
Can a 125 kHz tag work on a Arduino?
No, the 125 kHz tags won’t work with the 13.56 MHz reader. However you can work around this (if you want to) by using the 125 kHz tags with a different reader. Thanks for contributing an answer to Arduino Stack Exchange!
