Neeg Kev Sib Txuas Lus (NFC) vs Bluetooth
Neeg Kev Sib Txuas Lus (NFC) thiab Bluetooth yog ob qho tib si luv luv ntawm kev sib txuas lus wireless sib txuas nrog cov khoom siv hluav taws xob kom yooj yim thiab nyab xeeb ntawm cov khoom siv hluav taws xob.
Neeg Kev Sib Txuas Lus (NFC) yog lub tshuab txuas wireless uas tuaj yeem siv rau ob txoj kev sib cuam tshuam ntawm cov khoom siv hluav taws xob hauv ob peb centimeters. Bluetooth tseem yog lub tshuab wireless uas tau tsim los rau kev sib cuam tshuam ntawm kev sib txuas lus hauv 10-meter ntau yam tsis muaj kev sib txuas ntawm lub cev.
NFC yog qhov luv luv ntawm kev sib txuas lus ntau zaus wireless raws li kev sib txuas ntawm inductive, qhov uas xoob sib txuas inductive circuits tuaj yeem siv los qhia lub zog thiab cov ntaub ntawv ntawm cov khoom siv hauv ntau yam luv luv; tsuas yog nyob rau hauv ob peb centimeters. Qhov no yog qhov txuas ntxiv ntawm daim npav sib thooj uas txhawb nqa kev sib txuas lus RF rau ISO / IEC14443 thiab FeliCa smartcards thiab NFC li.
Bluetooth yog cov txheej txheem tsim tshwj xeeb rau kev sib txuas lus luv luv nrog qib siab ntawm kev ruaj ntseg. Nws tau tsim los ntawm Telecom Vendor Ericsson. Nws ua haujlwm hauv ISM band (Unlicensed Industry Scientific thiab Medical) uas yog 2.4 GHz. Bluetooth yog pob ntawv raws li kev sib txuas lus nrog Master thiab Slave architecture thiab mater ntaus ntawv tuaj yeem txuas mus rau xya lub twj tso kua mis.
Lub sijhawm teeb tsa rau NFC tsawg dua piv rau Bluetooth. NFC pab kiag li lawm tsim kev sib txuas nrog hauv 0.1 Sec. NFC ua haujlwm hauv 13.56 MHz thiab tuaj yeem mus txog qhov siab tshaj plaws cov ntaub ntawv tus nqi 424 Kb / s, thaum Bluetooth ua haujlwm hauv 2.4 GHz zaus thiab ncav cuag cov ntaub ntawv siab tshaj plaws 2.1 Mb / s. Qhov deb dav Bluetooth yuav ua haujlwm nyob rau hauv 10 m vojvoog qhov twg raws li NFC ua haujlwm max 20 cm.
Hais txog kev siv hluav taws xob, NFC siv lub zog qis piv rau cov khoom siv Bluetooth uas thaum cov khoom siv tsis muaj zog nws siv zog ntau dua.
Nyob rau hauv NFC, NFC ntaus ntawv tuaj yeem yog daim npav tsis sib cuag; NFC ntaus ntawv yog nquag thiab nyeem passive RFID thiab taw tes rau taw tes hom.
Qee Daim Ntawv Thov General ntawm NFC
(1) Electronic Money
(2) Electronic Identity Document
(3)NFC ntaus ntawv tuaj yeem nyeem NFC cim npe
(4) Electronic Key
(5) NFC ntaus ntawv tuaj yeem txuas nrog Bluetooth thiab Wi-Fi
