ACR122U yog dab tsi?

ACR122U yog PC-linked contactless smart card nyeem ntawv / sau ntawv tsim los ntawm 13.56 MHz contactless technology. Nws yog lub ntiaj teb thawj CCID-raws li tus neeg tsis paub daim npav nyeem ntawv / sau ntawv uas ua raws li ISO 14443 thiab ISO 18092. Cov cuab yeej no yog tsim los txhawb tsis tau tsuas yog MIFARE® thiab ISO 14443 Hom A thiab B daim npav nkaus xwb tab sis kuj FeliCa thiab NFC cov cim npe. Los ntawm kev siv txog li 424 Kbps nyeem / sau nrawm rau NFC tag nkag thiab mus txog 12 Mbps rau USB qhov nrawm, ACR122U tuaj yeem nyeem tau zoo los ntawm thiab sau rau ntau yam ntawv tsis sib cuag / cim npe. Nws tseem yog PC / SC-raws li uas tso cai rau kev sib koom ua haujlwm thoob plaws cov ntawv thov sib txawv thiab cov platforms. Koj tuaj yeem paub qhov yooj yim ntawm kev siv ACR122U, nrog nws qhov loj me thiab ntau yam uas nws muaj, rau cov ntawv thov xws li kev them nyiaj, kev tswj xyuas, sijhawm thiab kev tuaj koom, thiab kev thauj mus los loj.

 

ACR122U NFC Reader yog qhov zoo tagnrho rau ob qho tib si kev ruaj ntseg ntawm kev txheeb xyuas tus kheej thiab kev them nyiaj hauv online. Lwm daim ntawv thov ntawm ACR122U suav nrog kev nkag mus rau kev tswj hwm, e-them nyiaj, e-daim pib rau cov xwm txheej thiab kev thauj mus los loj, kev sau nqi ntawm txoj kev thiab kev txheeb xyuas lub network.

 

Rau kev nce qib ntawm kev ruaj ntseg, ACR122U tuaj yeem yooj yim ua ke nrog ISO 7816-3 SAM qhov. Kuj los muaj nyob rau hauv daim ntawv module, ACR122U NFC Reader tso cai yooj yim kev koom ua ke rau hauv cov tshuab loj. Qhov no suav nrog POS terminals, lub cev nkag mus rau lub cev thiab lub tshuab muag khoom.
