Mifare Plus cards can be easily integrated into existing systems that already use Mifare Classic cards.

Mifare Plus provides full bottom-up compatibility with Mifare Classic 1K and Mifare Classic 4K products. In turn, Mifare Plus products are designed to enhance the existing level of security when using contactless smart cards. Mifare technology is typically used in complex systems where privacy and data protection issues are important. Mifare Plus: When using access cards such as Mifare Plus, contains a number of security settings. This function is intended for integration into various ACS systems in which such inversion may be required. Key: In this field, you can specify the encryption key for Mifare IDs - 12 hexadecimal characters. The principle of the algorithm is that each identifier has its own individual encryption key. DiversificationĪ more secure application encryption algorithm 'Diversified keys' at any selected level of encryption (SL1, S元). Here you can specify the offset in bits for reading in blocks. After selecting the menu item 'To address', the command 'Read to address' becomes available. MifareClassic.Each sector of Mifare Classic can have its own access keys and conditions for writing / reading data.Ĭard Code: If the encryption key of the recorded cell in the card matches the encryption key in the reader, the card code (UID) will be transmitted to the controller at the output.Īt the address: Choosing this item, we get at the output from the reader information recorded in a specific block of memory card's memory. I've tried it with the following keys already: MifareClassic.KEY_DEFAULT * It must not be called from the main application thread. * It is an I/O operation and will block until complete. * This will read a 16-byte block in this sector * Authenticate the MAD Sector, sector 1, with key A */ Did Mifare change the keys in any way?ĮDIT: here's my code.

The strange thing is, even the KEY_DEFAULT and KEY_MIFARE_APPLICATION_DIRECTORY keys are not working on my blank cards. That can only mean that it uses an incorrect key for this type of card. To see how to do that, I've downloaded an example.

I'm trying to make an Android application to write NFC tags.
