Android实现NFC芯片制造商识别
时间：2023-03-03 23:00:00
如何识别？
通过NFC模块的Serial Number即UID，用户访问权限为R只读，每一个NFC独特的芯片序列号（UID），用户不能在出厂时重写。
Android如何实现？
- 通过Intent获取UID
/** * 读取nfcUID 返回String类型大写的UID * * 顺便加上这个测试，下面不用，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 {
/** * 用于输出16进制字符的小写字符数组 */ private static final char[] DIGITS_LOWER = {
'0', '1', '2', '3',
'4'

// two characters form the hex value.

;
}
return out
;
}
/** * 将字节数组转换为十六进制字符串 * * @param data byte[] * @param toLowerCase true 传换成小写格式 ， false 传换成大写格式 * @return 十六进制String */
public
static
String
encodeHexStr
(
byte
[

{
return
encodeHexStr

/** * 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 */

- 通过UID去查询厂商
