RFID uye NFC zvakajairika zviyero uye zvikumbiro

Rid uye nfc vane vakawanda kufanana. Pamusoro pekushandiswa uye frequency mabhendi, ivo vanogovanawo manyorerwo emasango. Nhasi, ini ndichasuma maviri ezvimwe zvinhu zvakajairika zvakajairika.

RFID:

Vanhu vazhinji vanowana pfungwa yavo yekushambadzira kubva kuIBM yekushambadzira: Mwana wekuyaruka ari muchitokisi anozadza jasi rake rekutarisa kuti agamuchire bhiri rake pasina kubhadhara. Kushambadzira uku kunoratidza vanhu nenzira yakajeka kushandiswa kwerusid muhupenyu hwezuva nezuva.

RFID (redhiyo redhiyo kuzivikanwa) inzvimbo yekuzivikanwa otomatiki inoshandisa mafungu eredhiyo ekutaurirana. Iyo yekutanga nheyo yekuzadzisa otomatiki yekuzivikanwa yezvinhu kuburikidza nekutaurirana data pakati pekuverenga musoro uye iyo tag yakasungirirwa nechinhu kuburikidza neyemagetsi componnet kana kuti inductive coupling. Kuzivikanwa otomatiki kunoreva kushandiswa kwechimwe chishandiso chekuziva, kuburikidza neiyo nzvimbo yekuzivikanwa

Iyo main frequency mapoka erfied ndeye: 125khz, 134.2khz, 13.56mhz, 860 {14} 960mhz, 2.45GHZ uye 5.8GHZ. RFID Systems ine dzakasiyana dzekushanda nguva dzinoshanda zvine akasiyana madaro ekushanda uye akasiyana masisitimu ekushandisa. Low Frequency Band (LF, 125khz, 134.2khz Iyo RFID System tekinoroji yakakwirira frequency (HF, 13.56mhz) yanga yakura, iyo inoshandiswa zvakanyanya mukudzora kwekuwana, zvekufambisa zvine hungwaru uye zvimwe zvinhu. LF uye HF Frequency Band Shanda neInductively Colled Mode, kazhinji ine diki diki yekushanda kure. Iyo inoshanda inoshanda yekuenda kwemagetsi emamaki multra-yakakwira frequency bhendi (UHF, 860-960 MHZ) Rini system, iyo yakakodzera mamirimita, inokodzera ketani uye imwe minda uye imwe minda. Microwave Frequency Bands (2.45GHZ uye 5.8GHZ) inoiswa kune manejimendi manejimendi uye mugwagwa mukuru wekuunganidza. UHF uye microwave frequency mabhendi anoshanda mune electromagnetic coupling mode, ine refu kushanda kure.

NFC:

NFC inomiririra padhuze nemumunda kutaurirana tekinoroji. Kuvandudzwa nePhilips uye Sony, NFC ndeyecherechedzo yekuzivisa NFC inopa iyo yakapusa, kubata {} inobvumidza vatengi kuchinjanisa ruzivo, kuwana zvemukati uye masevhisi nenzira yakapusa uye intuitive. NFC inovandudzwa pahwaro hweRFID, NFC haina kunyanya kusiyana neRFID mune kukosha, iyo yakavakirwa pachiitiko chekutapurirana pakati pezvinhu zviviri padyo nenzvimbo.
