Android识别NFC芯片制造商的方法
如何识别？
通过NFC模块的Serial Number即UID，用户访问权限为R只读，每颗NFC芯片独有序列号（UID），在出厂时写入，用户不能改写。
Android如何实现？通过Intent获取UID
/**
* 读取nfcUID 返回String类型大写的UID
*
* 这个测试顺便加上的，下面用不到，做个笔记~~
*
*/
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);
}
/**
* 读取nfcUID 返回byte[]数组
*
*/
public static byte[] readUID(Intent intent) throws UnsupportedEncodingException {
Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
return tagFromIntent.getId();
}
HexUtil工具类：
public class HexUtil {
/**
* 用于建立十六进制字符的输出的小写字符数组
*/
private static final char[] DIGITS_LOWER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'a', 'b', 'c', 'd', 'e', 'f'};
/**
* 用于建立十六进制字符的输出的大写字符数组
*/
private static final char[] DIGITS_UPPER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'A', 'B', 'C', 'D', 'E', 'F'};
/**
* 将字节数组转换为十六进制字符数组
*
* @param data byte[]
* @param toDigits 用于控制输出的char[]
* @return 十六进制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;
}
/**
* 将字节数组转换为十六进制字符串
*
* @param data byte[]
* @param toLowerCase <code>true</code> 传换成小写格式 ， <code>false</code> 传换成大写格式
* @return 十六进制String
*/
public static String encodeHexStr(byte[] data, boolean toLowerCase) {
return encodeHexStr(data, toLowerCase ? DIGITS_LOWER : DIGITS_UPPER);
}
/**
* 将字节数组转换为十六进制字符串
*
* @param data byte[]
* @param toDigits 用于控制输出的char[]
* @return 十六进制String
*/
protected static String encodeHexStr(byte[] data, char[] toDigits) {
if (data == null) {
return "";
}
return new String(encodeHex(data, toDigits));
}
}
通过UID去查询厂商

private static final String MNF_UNKNOWN = "Unknown Manufacture";
public static final Map<Byte, String> ManufacturerName;
