Tagmo – Android, NFC-enabled phones. Tagmo doesn’t need to be sideloaded anymore! It’s coming to Google Play! Tagmo is the simplest and most common way to make amiibo cards, and it’s my personal favorite. I love .

If the UID is the card's serial number, then you can't change it. Mifare cards allow .
If the UID is the card's serial number, then you can't change it. Mifare cards allow you to store about 1K of data on the card. You could easily have an address field on the card.

Perhaps you could help us by supplying a link to the documentation you are using! If the UID is the card's serial number, then you can't change it. Mifare cards allow you to store about 1K of data on the card. You could easily have an address field on the card.In this tutorial, we are going to learn how to use RFID/NFC with Arduino. The RFID/NFC system includes two components: reader and tag. There are two popular RFID/NFC readers: RC522 and PN532 RFID/NFC reader. The RFID RC522 module can be used in various practical applications, including: Access Control Systems: Secure your home or office by granting access only to authorized RFID tags. Attendance Systems: Track employee or student attendance by scanning RFID cards.
It is not clear to me exactly what you want, but I think you are asking about changing the key returned from an RFID tag. Some can be re-written, but unless you are using a key with built in encoding (think Keyloc with the rolling code/encryption), if someone can read the card, they can clone it. 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).
Here in this project, we are using Arduino and relay to trigger the Electric Door Lock and RFID to authenticate, so your RFID tag will act as a key. If you place the wrong RFID card near the RFID reader a buzzer will beep to alert you about the wrong card.I will explain how an RFID reader works and how to use one. Enjoy :) Using an Arduino board, a common RFID reader (MFRC522), and a few RFID tags/cards, we will be exploring methods for reading and writing RFID information in an attempt to understand how.
I bought a lot of blank RFID Mifare 4k tags. Their default Authentication KEY A and KEY B is FF FF FF FF FF FF. Now I want to change them to something else. I'm using APDU structure. I'm sending commands like this and it works well: byte[] baData = { . What should i do to be able to change this factory key?
