NFC / RFID
This RFID tag is really unique: it works with mobile phones just like other RFID tags, but you can reprogram it over I2C. The tag shows up as an ISO/IEC 15693 (13.56MHz) chip which is readable by phones and tablets.
This is a blank 13.56MHz RFID/NFC Keyfob with an NTAG213 chip - often used for train/bus passes, information sharing, and contactless payment.
This NFC Antenna is a 13.56MHz antenna for Near Field Communication
The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC.
This tiny flexible micro NFC/RFID tag is super small, and contains an NTAG203 chip plus antenna.
Grove - NFC (ST25DV64) is a flexible and innovative NFC/RFID tag board that utilizes the advanced ST25DV64K chip from STMicroelectronics.
Near Field Communication (NFC) is a set of short-range wireless technologies. It's behind daily applications such as access control systems and mobile payment systems.
The Grove-125KHz RFID Reader is a module used to read EM4100 RFID card information with two output formats: Uart and Wiegand. It has a sensitivity with maximum 7cm sensing distance.
The Adafruit PN532 NFC/RFID Shield for Arduino enables reading and writing of tags at 13.56 MHz with I2C or SPI connection, up to 10 cm range and easy mounting.
