mifare

I know. This question asked before under same tag and same name here . But the answers are useless for me. and i opened again for real answers. I have pc/sc reader and Contactless card(mifare card), I can connect to the card and also I execute getdate command successfully, but when I want to authenticate I see this error "6982:Security status not satisfied" I've tried these 4 different commands for authentication but I get the same error for all of them. FF 88 00 00 06 FF FF FF FF FF FF FF 88 00 00 60 12 FF 88 00 00 05 01 00 12 60 00 FF 88 00 00 60 00 how can I authenticate to this card ? The

I am working on an application that required reading the mifare card serial number, the language I am working with is C#. I am new to mifare reader programming, so I am sorry for asking dumb question. At first I would like to know if there is a different between Mifare UID and Mifare Serial number. I have managed to get UID with the help of WinSCard library, but I cant figure it out how to get the card serial number which should be 10 digit numbers. I do appreciate if you could point me to the right direction. Thanks in advance for the help. Regards C# signature of SCardTransmit method

I am creating an app for NFC where my first objective is to get the tag uid from the mifare tag. When i press the tag button my activvity goes to second activity where i should be getting the tagID. I am getting error of resource lookup. I know i am doing some major mistakes but could not find it. Request you to please help.

I'm using an ACR122U reader with an NTAG213 card. The card is password (reading and writing) protected with the password 52 84 00 08 . What are the APDU commands I should run to authenticate the card and also to read pages 30 and 31 of it once authenticated? I know with the MiFare 1k I could load the password and authenticate a sector, but I'm not sure how authentication works with the NTAG213 cards with the ACR122U readers. With the ACR122U you would need to send direct commands to the PN532 NFC controller chip inside the reader in order to exchange such low-level commands. For instance, you

I have a problem trying to authenticate an Ultralight EV1 card using a PC/SC reader (specifically an ACR1222L) in Java. I'm able to write and read on an unprotected tag using the corresponding APDUs for ISO 14443-3 tags. However, I can't find a way to run the PWD_AUTH command since it is not part of the 14443-3 standard (or any native command for that matter). Is it possible to run this command (or any native command for that matter)? I have tried sending the following APDU {e0 00 00 24 07 1b ff ff ff ff 63 00} where 1b is the native command, ff ff ff ff is the password and 63 00 is the CRC_A

I am reading several hundred bytes from a DESFire card using APDU commands. The data application is authenticated, and the response MAC'ed. I submit a series of READ_DATA commands (0xBD), each retrieving 54 bytes+MAC while increasing read offset for each command. Will this operation go much quicker if I use a long READ with ADDITIONAL_FRAME (AF) instead of many sequential reads? I understand that a simple AF is 1 byte vs 8 bytes for a full READ DATA command, thus reducing the number of bytes transferred by ~10%. But will use of AF give additional performance benefits, for example because of

I'm trying to write a simple "Hello World" string to the first block of sector 0 on a Mifare 1K tag. The tag is brand new with default configuration. The sector trailer (block 3), when read, is: 00 00 00 00 00 00 00 00 ff 07 80 69 ff ff ff ff ff ff ff ff . Hence, the access conditions is ff 07 80 69 , meaning I can read and write on each block with key A. Still, I can't manage to write anything on the tag. Here's my code: try { mfc.connect(); boolean auth = false; auth = mfc.authenticateSectorWithKeyA(0,MifareClassic.KEY_DEFAULT); if (auth) { String text = "Hello, World!"; byte[] value = text
