Android識別NFC芯片制造商的方法
如何識別?
通過NFC模塊的Serial Number即UID,用戶訪問權限為R隻讀,每顆NFC芯片獨有序列號(UID),在出廠時寫入,用戶不能改寫。
Android如何實現?
通過Intent獲取UID
/** * 讀取nfcUID 返回String類型大寫的UID * * 這個測試順便加上的,下面用不到,做個筆記~~ * */ public static String readUID(Intent intent) throws UnsupportedEncodingException { Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); byte[] uid = tagFromIntent != null ? tagFromIntent.getId() : null; return HexUtil.encodeHexStr(uid, false); } /** * 讀取nfcUID 返回byte[]數組 * */ public static byte[] readUID(Intent intent) throws UnsupportedEncodingException { Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); return tagFromIntent.getId(); }
HexUtil工具類:
public class HexUtil {
/**
* 用於建立十六進制字符的輸出的小寫字符數組
*/
private static final char[] DIGITS_LOWER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'a', 'b', 'c', 'd', 'e', 'f'};
/**
* 用於建立十六進制字符的輸出的大寫字符數組
*/
private static final char[] DIGITS_UPPER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'A', 'B', 'C', 'D', 'E', 'F'};
/**
* 將字節數組轉換為十六進制字符數組
*
* @param data byte[]
* @param toDigits 用於控制輸出的char[]
* @return 十六進制char[]
*/
protected static char[] encodeHex(byte[] data, char[] toDigits) {
int l = data.length;
char[] out = new char[l << 1];
// two characters form the hex value.
for (int i = 0, j = 0; i < l; i++) {
out[j++] = toDigits[(0xF0 & data[i]) >>> 4];
out[j++] = toDigits[0x0F & data[i]];
}
return out;
}
/**
* 將字節數組轉換為十六進制字符串
*
* @param data byte[]
* @param toLowerCase <code>true</code> 傳換成小寫格式 , <code>false</code> 傳換成大寫格式
* @return 十六進制String
*/
public static String encodeHexStr(byte[] data, boolean toLowerCase) {
return encodeHexStr(data, toLowerCase ? DIGITS_LOWER : DIGITS_UPPER);
}
/**
* 將字節數組轉換為十六進制字符串
*
* @param data byte[]
* @param toDigits 用於控制輸出的char[]
* @return 十六進制String
*/
protected static String encodeHexStr(byte[] data, char[] toDigits) {
if (data == null) {
return "";
}
return new String(encodeHex(data, toDigits));
}
}
通過UID去查詢廠商
