read mifare card uid Mifare Card Serial Number is the unique identifier defined in ISO 14443-3A. There are 3 types of UID defined in the standard - single (4 bytes), double (7 bytes) and triple (10 bytes). Only in first versions of the Mifare card, the UID was 4 bytes but now have migrated to 7 bytes. The problems seems to be that it's not possible to emulate/modify the sector 0, .

Only in first versions of the Mifare card, the UID was 4 bytes but now have migrated to 7 bytes.Reading the UID. The steps required in reading the UID from a contactless card requires the following steps. 1. Get context handle (SCardEstablishContext) 2. Connect to the card on the reader (SCardConnect) 3. Send the Get Data Command using SCardTransmit. You should use APDU commands for this to work. The command to get UID is 0xFF,0xCA,0x00,0x00,0x00 in case of a mifare card. Follow this link and look under high level api. This should give you an idea. I have a card reader that always report 64 bits, and can read cards with 4 or 7 byte UIDs. As an example, I see it can report: 04-18-c5-82-00-00-00-00 - a 4-byte UID in the form uid0-uid1-uid2-uid3-00-00-00-00
This document shows the use of UIDs in contactless smartcard systems. It indicates recommendations about the Random ID, mixed use of 4-byte and 7-byte UIDs in the same system, and it describes the options how to upgrade 4-byte UID systems to . Mifare Card integration via C# sample code and .NET library to read unique identifier (UID, CSN), authenticate and read card data using PC/SC card readers.
By default, Read-a-Card will read the CSN/UID of a contactless MIFARE card. But if instead you wish to read, for example, a specific sector of a MIFARE card, then Read-a-Card can return that data, formatted according to your requirements, using a software plug-in.PCSC Mifare Program is a program that allows you to read and write Mifare cards using the ACR122U NFC Reader. It can be used to modify the UID of gen3 magic cards. The card types include the following: S70 4K 7B, S70 4K 4B, S50 1K 7B, S50 1K 4B, Mifare Mini, Ultralight EV1, Mifare DESFire EV1, NTAG213, NTAG215, and NTAG216.
The value XXXXXXXXXXXXXX is the UID of the card (or all zeros if the card is in random anti-collision identifier mode). Note that there even exists a parser for the MIFARE DESFire version information here (as ThomasRS pointed out in a comment).
By default, Read-a-Card will read the CSN/UID of a contactless MIFARE Classic card. If instead you wish to read a specific sector of a MIFARE Classic card, you will need the MIFARE Sector Decoder plug‑in to ensure Read-a-Card can return that data, formatted according to .Mifare Card Serial Number is the unique identifier defined in ISO 14443-3A.
