The Xadow NFC v2 features the most popular NFC chip-set on the market - a highly integrated transceiver module PN532. This chip set is very powerful and can be seen in most of smartphones and NFC devices. It can be used to read and write to tags and cards, acting like NFC tags. Currently we’ve developed Arduino libraries to support reading and writing to MIFARE Class and MIFARE Ultralight Card.
The board also adopts the new 11 PIN Xadow connector to improve the flexibility of module connections.
Near Field Communication (NFC)
Near Field Communication (NFC) is the set of protocols for the communication of electronic devices that are close proximity to each other (typically 10cm or less). Full NFC devices usually have three working mode:
Card Emulation: typically used in entrance card, or in smartphones to let them acts like smart cards to perform payment process or ticketing
Reader/Writer Mode: used to read the information stored in the NFC tags
Peer-to-peer Mode : used for data exchanging between devices
Features:
Open source and modular design

Xadow nfc v2 的特點是最受歡迎的 nfc 晶片-在市場上-一個高度集成的收發模組 PN532。這個晶片集是非常強大的, 可以看到在大多數的智慧手機和 NFC 設備。它可以用來讀寫標籤和卡片, 就像 NFC 標籤一樣。目前, 我們已經開發了 Arduino 庫, 以支援讀寫 MIFARE 類和 MIFARE 超輕型卡。
該主機板還採用新的11針 Xadow 連接器, 以提高模組連接的靈活性。
近場通信 (NFC)
近場通信 (NFC) 是電子設備通信的一套協定 (通常是10cm 或更少)。全 NFC 設備通常有三工作模式:
卡類比: 通常用於門禁卡, 或智慧手機, 讓他們的行為像智慧卡, 執行付款過程或票務
讀寫模式: 用於讀取存儲在 NFC 標籤中的資訊
對等模式: 用於設備間的資料交換
