Android识别NFC芯片制造商的方法是什么

本篇文章为大家展示了Android识别NFC芯片制造商的方法是什么，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

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 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[] 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

public class Manufacturer {    private static final String MNF_UNKNOWN = "Unknown Manufacture";    public static final Map ManufacturerName;    static {        ManufacturerName = new HashMap<>();        ManufacturerName.put((byte)1, "Motorola");        ManufacturerName.put((byte)2, "STMicroelectronics SA ");        ManufacturerName.put((byte)3, "Hitachi, Ltd");        ManufacturerName.put((byte)4, "NXP Semiconductors");        ManufacturerName.put((byte)5, "Infineon Technologies AG ");        ManufacturerName.put((byte)6, "Cylink");        ManufacturerName.put((byte)7, "Texas Instrument");        ManufacturerName.put((byte)8, "Fujitsu Limited");        ManufacturerName.put((byte)9, "Matsushita Electronics Corporation, Semiconductor Company");        ManufacturerName.put((byte)10, "NEC");        ManufacturerName.put((byte)11, "Oki Electric Industry Co.
