Technical Background Ntawm NFC

Raws li cov ntaub ntawv tseem ceeb, nyob ib puag ncig xyoo 2003, Sony Corporation thiab tom qab ntawd Philips Semiconductor (tam sim no NXP Semiconductor) tau koom tes los tsim kom muaj kev nyab xeeb dua, sai dua thiab siv tau wireless kev sib txuas lus thev naus laus zis raws li kev tsis sib cuag RF card technology. Tom qab ob peb lub hlis ntawm kev tshawb fawb thiab kev tsim kho, ob tog tau sib koom ua ke tso tawm cov cuab yeej sib txuas lus wireless uas sib haum nrog IS014443 contactless card raws tu qauv, npe hu ua NFC (Neeg Field Communication), thiab cov kev sib txuas lus tshwj xeeb hu ua NFCIP -1 specification. Tsis ntev tom qab tso tawm ntawm NFC thev naus laus zis, ob tog tau xa daim qauv qauv mus rau European Computer Manufacturers Association (ECMA), thov los ua tus qauv kev sib txuas lus nyob ze thiab tau txais kev lees paub sai raws li tus qauv ECMA.340. Tom qab ntawd, nrog kev pab ntawm ECMA, lawv tau xa daim ntawv thov txheej txheem rau ISO / IEC thiab thaum kawg tau lees paub tias yog ISO / IECl8092 tus qauv.
