NFC (Near Field Communication), zn\u00e1m\u00e1 jako bezdr\u00e1tov\u00e1 technologie kr\u00e1tk\u00e9ho dosahu, je sada komunika\u010dn\u00edch protokol\u016f, kter\u00e9 umo\u017e\u0148uj\u00ed jednoduchou a bezpe\u010dnou obousm\u011brnou interakci mezi elektronick\u00fdmi za\u0159\u00edzen\u00edmi. V roce 2004 zalo\u017eily spole\u010dnosti Nokia, Philips a SONY f\u00f3rum Near Field Communication (NFC), kter\u00e9 definovalo p\u011bt typ\u016f zna\u010dek, kter\u00e9 poskytuj\u00ed r\u016fzn\u00e9 komunika\u010dn\u00ed rychlosti a mo\u017enosti z hlediska konfigurovatelnosti, pam\u011bti, zabezpe\u010den\u00ed, uchov\u00e1v\u00e1n\u00ed dat a kontinuity z\u00e1pisu.<\/p>\n
Typ 1 zna\u010dky f\u00f3ra NFC:
\nNFC tag Type1 je zalo\u017een na standardu ISO\/IEC 14443A. NFC tag Type1 je nejjednodu\u0161\u0161\u00ed \u010dip ze v\u0161ech p\u011bti typ\u016f a tak\u00e9 nejpomalej\u0161\u00ed \u010dip pro p\u0159enos dat. Kv\u016fli jednoduchosti je v\u0161ak mo\u017en\u00e9 na \u010dipu Type1 zaplnit i v\u00edce pam\u011bti. Typick\u00fdm tagem Type1 IC je Innovision Topaz 512 a aplikace typu NFC tag Type1 jsou obvykle aplikace pro jednor\u00e1zov\u00e9 z\u0159izov\u00e1n\u00ed nebo aplikace pouze pro \u010dten\u00ed atd.<\/p>\n
Typ 2 zna\u010dky f\u00f3ra NFC:
\n\u0160t\u00edtky typu NFC Type2 jsou zalo\u017eeny na standardu ISO14443A. \u0160t\u00edtek NFC \u0160t\u00edtek typu Type2 je cenov\u011b v\u00fdhodn\u011bj\u0161\u00ed variantou, proto\u017ee poskytuje dostatek funkc\u00ed za spr\u00e1vnou cenu, aby uspokojil popt\u00e1vku trhu. Zna\u010dky NFC typu 2 lze \u010d\u00edst a p\u0159episovat a u\u017eivatel\u00e9 mohou zna\u010dky nakonfigurovat tak, aby se staly pouze pro \u010dten\u00ed. Typicky ozna\u010den\u00e9 NFC Type 2 ics jsou s\u00e9rie Enzienttag a MIFARE Ultralight s\u00e9rie. Aplikace NFC tag Type 2 jsou obvykle transakce s n\u00edzkou hodnotou nebo RFID vstupenky atd.<\/p>\n
Typ 3 zna\u010dky f\u00f3ra NFC:
\n\u0160t\u00edtek NFC Type 3 je zalo\u017een na syst\u00e9mu SONY FeliCa, vyr\u00e1b\u011bn\u00e9m v Japonsku, a je \u0161iroce pou\u017e\u00edv\u00e1n p\u0159edev\u0161\u00edm v Asii. Jde o propracovan\u00fd \u0161t\u00edtek, kter\u00fd nab\u00edz\u00ed \u0161irokou \u0161k\u00e1lu funkc\u00ed, ale p\u0159ich\u00e1z\u00ed tak\u00e9 s vy\u0161\u0161\u00ed cenovkou. Typick\u00fdm \u0161t\u00edtkem Type 3 IC je \u0159ada FeliCa S od Sony a aplikace pro \u0161t\u00edtek Type 3 jsou obvykle tranzitn\u00ed j\u00edzdenky, elektronick\u00e9 pen\u00edze, e-ID atd.<\/p>\n
Typ 4 zna\u010dky f\u00f3ra NFC:
\n\u0160t\u00edtky NFC typu 4 jsou definov\u00e1ny jako kompatibiln\u00ed s ISO14443A a standard B tak\u00e9 poskytuje podporu pro zabezpe\u010den\u00ed ISO\/IEC 7816. Tyto ikony NFC jsou p\u0159edkonfigurov\u00e1ny v dob\u011b v\u00fdroby, mohou \u010d\u00edst\/p\u0159episovat nebo pouze \u010d\u00edst a tak\u00e9 umo\u017e\u0148uj\u00ed vlastn\u00ed \u00fapravu obsahu NDEF. Typick\u00fdm IC ozna\u010den\u00fdm Type 4 je \u0159ada NXP Desfire a aplikace ozna\u010den\u00e9 NFC Type 4 jsou obvykle platebn\u00ed a bezpe\u010dnostn\u00ed.<\/p>\n
Typ 5 zna\u010dky f\u00f3ra NFC:
\nNejnov\u011bj\u0161\u00ed specifikace NFC Type 5, zve\u0159ejn\u011bn\u00e1 v roce 2015, je zalo\u017eena na technologii RFID definovan\u00e9 specifikac\u00ed ISO\/IEC 15693. Specifikace ISO\/IEC 15693 byla p\u016fvodn\u011b vyvinuta tak, aby umo\u017e\u0148ovala dlouh\u00e9 RF provozn\u00ed dosahy a\u017e 1,5 metru. F\u00f3rum NFC zvolilo podporu aktivn\u00edho komunika\u010dn\u00edho re\u017eimu, kter\u00fd umo\u017e\u0148uje v\u00fdkon p\u0159enosu dat podobn\u00fd technologii RFID podporovan\u00e9 F\u00f3rem NFC, ale omezuje \u010dtec\u00ed vzd\u00e1lenost za\u0159\u00edzen\u00ed NFC. Typick\u00e9 NFC ozna\u010den\u00e9 Type 5 ics jsou \u0159ady NXP ICode a ST Microelectronics \u0159ady ST25TV.
