You can use WinSCard library's SCardGetStatusChange function to observe changes via background worker thread.To read a status change, the SCardGetStatusChange function is called which has the following parameters: LONG WINAPI SCardGetStatusChange( _In_ SCARDCONTEXT hContext, _In_ DWORD dwTimeout, _Inout_ LPSCARD_READERSTATE rgReaderStates, . SCardGetStatusChange () is a function to get the status of a list of readers and wait for events. The function API is: LONG SCardGetStatusChange(. SCARDCONTEXT hContext, DWORD dwTimeout, SCARD_READERSTATE * rgReaderStates, DWORD cReaders. )
I'm working with ACR122U on Linux. I'm using a separate thread to detect reader and card arrival / removal. The timeout argument to the SCardGetStatusChange() is set to INFINITE. When not performing any card access, I can see removal of . Google: APDU, SCardConnect, SCardGetStatusChange. Also you need SDK of your CARD TYPE (mifare classic 1K is most popular). All cards types have own memory organization and commands. It's enough to begin your journey. PS: This deivce allow: read/write NFC, Mifare 1K, Mifare 4K cards/tags, biomeric passports, bank cards. based on 13.56MHz. The SCardGetStatusChange function blocks execution until the current availability of the cards in a specific set of readers changes. The caller supplies a list of readers to be monitored by an SCARD_READERSTATE array and the maximum amount of time (in milliseconds) that it is willing to wait for an action to occur on one of the listed readers .
