Cov lus nug zoo dua tsis yog:

Qhov twg RFID nti yog qhov zoo tshaj?

Nws yog:

Cov nti twg phim rau daim ntawv thov, tus nyeem ntawv, kev ruaj ntseg yuav tsum tau muaj, qhov system architecture thiab daim ntawv pov thawj lifecycle?

Dab tsi Koj Yuav Tsum Xa Koj Tus Neeg Siv RFID Ua Ntej Thov Daim Ntawv Tso Cai?

Tus neeg muag khoom tuaj yeem ua qhov kev pom zoo ntau dua thaum qhov kev xav tau meej meej.

Npaj cov ntaub ntawv hauv qab no:

1. Daim ntawv thov:nkag mus, pib, tsev so, thauj, loyalty, ua tswv cuab lossis lwm yam kev siv
2. Tam sim no nyeem ntawv chaw tsim tshuaj paus thiab qauv:yog tias qhov system twb muaj lawm
3. Daim npav tam sim no lossis chip qauv:tshwj xeeb tshaj yog rau kev hloov pauv lossis kev tsiv teb tsaws chaw
4. Yuav tsum muaj kev ruaj ntseg theem:suav nrog yam kev hem thawj uas qhov system yuav tsum daws
5. Cov ntaub ntawv xav tau:dab tsi tiag tiag yuav tsum tau muab cia rau hauv daim ntawv pov thawj
6. Daim ntawv thov qauv:ib daim ntawv thov los yog ob peb
7. Smartphone xav tau:seb puas yuav tsum muaj kev sib cuam tshuam NFC mobile
8. Lub cev hom:card, wristband, key fob, daim pib lossis lwm daim ntawv pov thawj
9. Lub neej vam meej:ib hnub, ob peb hlis lossis ntau xyoo
10. Ntim:qauv kom muaj nuj nqis thiab xav tau ntau lawm
11. Personalization:luam ntawv, UID tuav, encoding lossis lwm yam ntaub ntawv xav tau
12. Kev kuaj:nyeem ntawv thiab software validation yuav tsum tau ua ntej ntau lawm

Yog tias koj tsis tuaj yeem muab tus qauv chip tiag tiag, xa cov qauv ntawv pov thawj uas twb muaj lawm ua ke nrog cov neeg nyeem thiab cov ntsiab lus ntawm cov txheej txheem es tsis yog kwv yees los ntawm qhov pom.

MIFARE Kev Xaiv Xeem Xeem

• Txhais daim ntawv thov ua ntej xaiv lub nti.
• Txhais qhov kev hem thawj ntawm kev nyab xeeb tiag tiag tsis yog siv lo lus "kev nyab xeeb" raws li qhov yuav tsum tau ua.
• Paub meej tias tus nyeem ntawv tseeb, firmware thiab software ib puag ncig.
