Android识别NFC芯片制造商的方法
来源：jb51　　时间：2021/11/29 9:29:23　　对本文有异议

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

  1.     /**
  2.      * 读取nfcUID 返回String类型大写的UID
  3.      * 
  4.      * 这个测试顺便加上的，下面用不到，做个笔记~~
  5.      * 
  6.      */
  7.     public static String readUID(Intent intent) throws UnsupportedEncodingException {
  8.         Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
  9.         byte[] uid = tagFromIntent != null ? tagFromIntent.getId() : null;
  10.         return HexUtil.encodeHexStr(uid, false);
  11.     }
  12.     
  13.     /**
  14.      * 读取nfcUID 返回byte[]数组
  15.      * 
  16.      */
  17.     public static byte[] readUID(Intent intent) throws UnsupportedEncodingException {
  18.         Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
  19.         return tagFromIntent.getId();
  20.     }

HexUtil工具类：

  1. public class HexUtil {
  2.  
  3.     /**
  4.      * 用于建立十六进制字符的输出的小写字符数组
  5.      */
  6.     private static final char[] DIGITS_LOWER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
  7.             'a', 'b', 'c', 'd', 'e', 'f'};
  8.  
  9.     /**
  10.      * 用于建立十六进制字符的输出的大写字符数组
  11.      */
  12.     private static final char[] DIGITS_UPPER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
  13.             'A', 'B', 'C', 'D', 'E', 'F'};
  14.  
  15.     /**
  16.      * 将字节数组转换为十六进制字符数组
  17.      *
  18.      * @param data     byte[]
  19.      * @param toDigits 用于控制输出的char[]
  20.      * @return 十六进制char[]
  21.      */
  22.     protected static char[] encodeHex(byte[] data, char[] toDigits) {
  23.         int l = data.length;
  24.         char[] out = new char[l << 1];
  25.         // two characters form the hex value.
  26.         for (int i = 0, j = 0; i < l; i++) {
  27.             out[j++] = toDigits[(0xF0 & data[i]) >>> 4];
  28.             out[j++] = toDigits[0x0F & data[i]];
  29.         }
  30.         return out;
  31.     }
  32.  
  33.     /**
  34.      * 将字节数组转换为十六进制字符串
  35.      *
  36.      * @param data        byte[]
  37.      * @param toLowerCase <code>true</code> 传换成小写格式 ， <code>false</code> 传换成大写格式
  38.      * @return 十六进制String
  39.      */
  40.     public static String encodeHexStr(byte[] data, boolean toLowerCase) {
  41.         return encodeHexStr(data, toLowerCase ? DIGITS_LOWER : DIGITS_UPPER);
  42.     }
  43.  
  44.     /**
  45.      * 将字节数组转换为十六进制字符串
  46.      *
  47.      * @param data     byte[]
  48.      * @param toDigits 用于控制输出的char[]
  49.      * @return 十六进制String
  50.      */
  51.     protected static String encodeHexStr(byte[] data, char[] toDigits) {
  52.         if (data == null) {
  53.             return "";
  54.         }
  55.         return new String(encodeHex(data, toDigits));
  56.     }
  57. }
  58.

通过UID去查询厂商

  1. public class Manufacturer {
  2.  
  3.     private static final String MNF_UNKNOWN = "Unknown Manufacture";
  4.  
  5.     public static final Map<Byte, String> ManufacturerName;
  6.  
  7.     static {
  8.         ManufacturerName = new HashMap<>();
  9.         ManufacturerName.put((byte)1, "Motorola");
