cnet rfid read write I'm trying to read/write data from a RFID using the serial port in C#. I've used the code below but it doesn't work. I've wrote a command from the manual, but the data received is totally different: Manual example. public partial class Form1 : Form.

I'm staring at a table covered in circuitry, a solderless "breadboard," a bunch of wire, an antenna, and some other components--all the things I've been given to build a rudimentary RFID reader.

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? I'm trying to read/write data from a RFID using the serial port in C#. I've used the code below but it doesn't work. I've wrote a command from the manual, but the data received is totally different: Manual example. public partial class Form1 : Form. I am working on a project which uses RFID smart card to access room, so when user access room his/her details should be read and stored in database, and also can put restriction on card like time and number of access per day. So is there any solution for this to write cards and read them in asp.net core. C#.
Can an RFID blocking card keep someone from "reading" your card without your knowledge? I put it to the test. Credit and debit cards contain RFID contactless technology.
Using radio waves, RFID can write, store and transmit information without requiring line-of-sight scanning. Easily reading data from RFID tags allows you to identify single items or entire batches of goods simultaneously.RFID uses radio waves produced by a reader to detect the presence of (then read the data stored on) an RFID tag. Tags are embedded in small items like cards, buttons, or tiny capsules. These readers also use radio waves in some systems to write new information to the tags. In summary, reading RFID tags with an RFID reader involves powering on the reader, positioning the reader and tags correctly, launching the RFID reader software, activating the reading function, capturing the tag data, and collecting and processing the data as needed.
the above method writes data on an rfid tag in the line serialPort1.Write(writeByteArray, 0, writeByteArray.Length); writeByteArray is the size of the data which is exceeding the limit of the RFID tag, my boss .
