This value is contained in the serial number that you received from the reader: 09 002E4EA2 CB. Therefore, you could do something like this to print the value (use sprintf(), if you need the leading zeros): void loop() {. int serialNumber = 0; int charIndex = 0; int currentChar; if .

My problem is that when I read a RFID tag I get a bunch of hexadecimal values and I am unable to retrieve the actual serial number value from them as it is not a straightforward decimal to hex encoding. I have found several items on the internet to read in the HEX code, but what about the numeric code on the tag? For instance, I have one tag that has the HEX result of 0D0031EF53 the number on the tag is 0003272531 is… Let's break down this code step by step to understand what each part does. The code sets up an RFID reader with an Arduino, reads RFID tags, and prints their UIDs to the Serial Monitor while also controlling an LED. Reading Data from a RFID tag. After having the circuit ready, go to File > Examples > MFRC522 > DumpInfo and upload the code. This code will be available in your Arduino IDE (after installing the RFID library). Then, open the serial monitor. You should see something like the figure below: Approximate the RFID card or the keychain to the reader.
rfid serial number
The Card Serial Number is specific to the application loaded on to the card. It can only be accessed by that application via an encryption key. If the card had several applications loaded on to it (unlikely but possible), then each could have a different CSN.In this project, you'll learn to read an RFID tag using the Innovations ID-12 reader and an Arduino Duemilanove. In this example, we will use a tag with the serial number “119 38 185 95” as the right tag. Or the key. You can edit this serial number in the code below.
In this post we will go over how to use the RC522 RFID Module with Arduino. We’ll focus on basics, module pins, how to connect to Arduino, programming in Arduino IDE, and testing. The main focus will be around reading an RFID tag’s UID (Unique ID). To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the type, and the .
