Internet of Things Identification Technology hi i hria em: RFID leh NFC te hi eng nge an danglamna?

Internet of Things hi technology pawimawh pathum atanga siam a ni a, chungte chu connectivity, identification leh data manipulation te an ni.

NFC 100 a ni.

Field Communication (NFC) bulah a awm. NFC hi mobile phone hmanga inbiakpawhna interface hman tlanglawn tak a ni. Smart device te hian an inhnaih tawn a, data an inthleng thei a ni. NFC device te pawhin passive NFC tag hmangin an inbiak theih bawk. Communication method pawh RFID nen a inang vek. Communication protocol bakah hian NFC standard hian data exchange atana format a tarlang bawk. Integrated sensor card reader, sensor card leh point-to-Point functions chu NFC chip pakhatah a function a, chu chuan identification leh data exchange chu a inmil devices te nen hla vak lovah a hmang thei a ni.

Radio Frequency hriat theihna .

Contactless Radio Frequency Identification (RFID) hi a bul berah chuan wireless communication technology a ni a, wireless electromagnetic wave hmangin data pawh a thawn chhuak thei a ni. Mahse, communication technology pangngai ang lo takin, a tum ber chu phone call emaw text message thawn emaw a ni lo. RFID hi object nena inzawm tags te hriatchhuah leh track nan hman a ni ber a, chutiang chuan object management a thleng thei ang.

NFC leh RFID inthlauhna .

1. Hnathawh tam dan .

NFC hi 13.56MHz band hmanga RFID technology subset anga hriatthiam theih a ni a, RFID pawh band dang a awm bawk.

RFID hian working frequency band tam tak a nei a, low frequency band chu 125kHz a ni a, high frequency band chu 13.56MHz a ni a, ultra{2}}high frequency band chu 433.92MHz leh 915MHz a ni a, microwave frequency band chu 2.45GHz a ni.

2. Inbiakpawhna hlat zawng .

NFC hi near field communication an ti a, a takah chuan communication distance hi a hnai hle a, 0.1m aia tam a ni lo.

RFID chi hrang hrang a awm a, hriat theih distance pawh a danglam bawk. RFID access card ang bawkin recognition distance pawh NFC nen a inang tlangpui. Mahse, ETC ang chi application scenario atan chuan recognition distance rei zawk a ngai a ni. Long distance RFID-a hriat theihna hlat zawng chu meter sawm vel emaw, meter za tam tak emaw pawh a ni thei.

3. Application scenario 1000 a awm.

RFID hi active emaw passive emaw pawh nise, a hna ber chu thil hriat chian a la ni reng. Logistics, transportation leh warehousing te hian RFID technology hmangin bungrua an lo enfiah thin a ni.

NFC chip hi a inzawm tlat a, card reader leh tags te pawh a tel. Chu bakah, NFC-a -way communication capability pahnih hi a sang chho hle bawk. Phên dangin sawi ila, NFC hi identification tag ang chauh ni lovin, data exchange atana kawng hnih-way communication method angin hman theih a ni. Tunah hian NFC hi payment domain-ah hman tam ber a ni.
