RFID Reader/Writer RC522 SPI S50 with RFID Card and Tag

<p>Do you want to know the work of RFID Reader/Writer RC522 SPI S50 CARD AND KEYCHAIN, then this Product is best for you . With this Product, you can detect radio waves produced by a reader to detect the presence of (then read the data stored on) an RFID tag</p> <p>This is <strong>RFID Reader/Writer RC522 SPI S50 CARD AND KEYCHAIN which works on non-contact 13.56mhz communication</strong>, is designed by NXP as <strong>low power consumption, low cost, and compact size read and write chip</strong>, is the best choice in the development of smart meters and portable hand-held devices.</p> <p>It uses an advanced modulation system,  <strong>fully integrated at 13.56MHz with all kinds of positive non-contact communication protocols. Support 14443A compatible answer signal</strong>. DSP deals with<strong> ISO14443A</strong> frames and error correction.</p> <p>This module can fit directly in handheld devices for mass production. The module uses the <strong>3.3V</strong> power supply and can communicate directly with any CPU board by connecting through the SPI protocol, which ensures reliable work, good reading distance.</p> <hr /> <h4><strong>Features :</strong></h4> <ol> <li>Highly integrated analog circuitry to demodulate and decode responses.</li> <li>Supports ISO/IEC 14443 A/MIFARE.</li> <li>Typical operating distance in reading/Write mode up to 50 mm.</li> <li>Supports ISO/IEC 14443 A higher transfer speed communication up to 848 kBd.</li> <li>SPI up to 10 Mbit/s.</li> <li>FIFO buffer handles 64 bytes send and receive.</li> <li>Flexible interrupt modes.</li> <li>Power-down by software mode.</li> <li>Programmable Timer.</li> <li>2.5 V to 3.3 V power supply.</li> <li>CRC coprocessor.</li> <li>Internal self-test.</li> </ol> <hr /> <h4><strong>Package Includes</strong></h4> <p>1 x RFID-RC522 Reader/Write Module<br />1 x Standard blank RFID card<br />2 x A Straight & right-angle header strip<br />1 x Special-shaped keychain RFID tag</p> <hr /> <h4><strong>Useful Links:</strong></h4> <p><a href=""http://playground.arduino.cc/Learning/MFRC522"" target=""_blank"" rel=""noopener noreferrer"">Arduino Playground for MFRC522</a></p> <p><a href=""http://www.instructables.com/id/Arduino-RC522-RFID-Door-Unlock/"" target=""_blank"" rel=""noopener noreferrer"">Arduino RC522 RFID Door Unlock</a></p> <p><a href=""http://www.electroschematics.com/11301/arduino-rfid-reader-rc522-access-control-system/"" target=""_blank"" rel=""noopener noreferrer"">Access Control System based on Arduino</a></p> <p><a href=""https://github.com/search?utf8=%E2%9C%93&q=MFRC522&type=Repositories&ref=searchresults"" target=""_blank"" rel=""noopener noreferrer"">Github Source code for various targets like PIC, AVR, ARM, and such</a></p>
