Android識別NFC芯片制造商的方法

第Android識別NFC芯片制造商的方法如何識別？

通過NFC模塊的SerialNumber即UID，用戶訪問權(quán)限為R只讀，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(xiàn)？

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~~

publicstaticStringreadUID(Intentintent)throwsUnsupportedEncodingException{

TagtagFromIntent=intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);

byte[]uid=tagFromIntent!=nulltagFromIntent.getId():null;

returnHexUtil.encodeHexStr(uid,false);

*讀取nfcUID返回byte[]數(shù)組

publicstaticbyte[]readUID(Intentintent)throwsUnsupportedEncodingException{

TagtagFromIntent=intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);

returntagFromIntent.getId();

}

HexUtil工具類：

publicclassHexUtil{

*用于建立十六進制字符的輸出的小寫字符數(shù)組

privatestaticfinalchar[]DIGITS_LOWER={0,1,2,3,4,5,6,7,8,9,

a,b,c,d,e,f

*用于建立十六進制字符的輸出的大寫字符數(shù)組

privatestaticfinalchar[]DIGITS_UPPER={0,1,2,3,4,5,6,7,8,9,

A,B,C,D,E,F

*將字節(jié)數(shù)組轉(zhuǎn)換為十六進制字符數(shù)組

*@paramdatabyte[]

*@paramtoDigits用于控制輸出的char[]

*@return十六進制char[]

protectedstaticchar[]encodeHex(byte[]data,char[]toDigits){

intl=data.length;

char[]out=newchar[l1];

//twocharactersformthehexvalue.

for(inti=0,j=0;ii++){

out[j++]=toDigits[(0xF0data[i])

out[j++]=toDigits[0x0Fdata[i]];

returnout;

*將字節(jié)數(shù)組轉(zhuǎn)換為十六進制字符串

*@paramdatabyte[]

*@paramtoLowerCasecodetrue/code傳換成小寫格式，codefalse/code傳換成大寫格式

*@return十六進制String

publicstaticStringencodeHexStr(byte[]data,booleantoLowerCase){

returnencodeHexStr(data,toLowerCaseDIGITS_LOWER:DIGITS_UPPER);

*將字節(jié)數(shù)組轉(zhuǎn)換為十六進制字符串

*@paramdatabyte[]

*@paramtoDigits用于控制輸出的char[]

*@return十六進制String

protectedstaticStringencodeHexStr(byte[]data,char[]toDigits){

if(data==null){

return

returnnewString(encodeHex(data,toDigits));

通過UID去查詢廠商
