Can RC522 read 125kHz?

Can RC522 read 125kHz?

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.

What is a 125kHz RFID?

You might know RFID as the technology that Big Brother uses to track your every move. RFID is useful for sensing and identifying tagged people and objects for access control, automation and a whole range of different applications. This basic RFID tag works in the 125kHz RF range and comes with a unique 40-bit ID.

How do you write an RFID code?

Here’s how you do it.

1. On the main screen, select “Basic RFID”.
2. Once the tag has been read, select the EPC number that appears on screen.
3. Then, select “Change EPC”.
4. A screen will pop up with the existing EPC, and you can use your smartphone’s keypad to change the EPC number to whatever you prefer in the character limit.

How does the mfrc522 library help the RFID module?

The MFRC522 library helps to decode and encode the incoming data from the RFID module and SPI helps to establish the SPI communication. These two libraries are dependent on each other. After initializing the libraries, the most important thing is to describe the reset and slave select (SS) pin through the following command:

When to use Arduino and mfrc522 for 6 Candles?

For instance, in 6 candles games, it is necessary to put all candles at a specified location for triggering the output. For that card under candles must stay at that position. Otherwise, it will disturb the sequence. We will use Arduino and mfrc522 to learn this concept.

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

How does a RFID reader communicate with a microcontroller?

The RC522 RFID Reader module is designed to create a 13.56MHz electromagnetic field that it uses to communicate with the RFID tags (ISO 14443A standard tags). The reader can communicate with a microcontroller over a 4-pin Serial Peripheral Interface ( SPI) with a maximum data rate of 10Mbps.
