rfid writer reader stack overflow Guess we have a RFID reader that can read a card number, these readers can connect to pc using RS232 or USB cable and so on. how i can interact with this device. in simple scenario i want to read the card no when reader read a card. any OS (but windows is preferred)
Following points are some of the limitations of NFC technology in general. 1. It can only works in shorter distances which is about 10-20 cm. 2. It offers very low data transfer rates which is about 106 or 212 or 424 Kbps. 3. It is very expensive for the companies to . See more

Assuming you are using a gen2 RFID tag, writing to the tag is fairly simple. I have a RFID card reader device from unknown company. I'd like to read/write to it using any programming language. My question: is there a general way to read/write cards (using C# as example)? Do I need a specific driver/API for every RFID reader?

What I'm doing is creating a library to work easily with the RFID reader/writer RC522 module. I need to create an object of the library MFRC522 in my .cpp file to be able to communticate with the module itself. This is the code for read data: * Reads data written by a program such as "rfid_write_personal_data.ino". * See: https://github.com/miguelbalboa/rfid/tree/master/examples/rfid_write_personal_data. * Uses MIFARE RFID card using RFID-RC522 reader. * Uses MFRC522 - Library I knew the PN532 module can read and write RFID card, but I did not know that the module can also PRETEND/FAKE as a NFC/RFID card/tag. In other words, it can do three things, (1) Read, (2) Write, (3) Pretend to be a card/tag. I bought a USB RFID reader/writer to develop an attendance application. Along with the device they given VB example to read/write RFID tags. But I want to do this in Java.
I don’t have any information on the RFID writer I use. Is a generic Chinese with no documentation. The tag is the EM4305. And the reader I use is based on EM4095 in read only config.
