NTAG vs MIFARE NFC Stickers: Wanem Chip Em i Stret?

Sapos yu wok long painimNFC stikalong sait bilong putim ol samting long paket, maketim, kontrolim rot bilong kisim samting, o painimaut olsem prodak i tru, namba wan disisen tru emNTAG vs MIFARE. Tupela wantaim em ol 'high-frequency (13.56 MHz) chips we i bihainim ISO/IEC 14443 standet, na tupela wantaim i ken kamap olsem ol liklik 'adhesive label', tasol ol i wokim bilong mekim ol narapela narapela wok.

Sotpela tok: NTAG NFC stika em i gutpela samting tru taim bikpela samting yu mas mekim em long fon, olsem opim wanpela URL, soim infomesen bilong prodak, rejistaim wanpela waranti, o kirapim wanpela ap. MIFARE NFC stika i fit long ol rida-na-sistem aplikesen olsem ekses kontrol, tiket, membasip, na klos-lup pemen, we tag em i wanpela kredensel insait long wanpela menesmen sistem.

Olsem na gutpela askim em i no wanem 'chip' i strong moa, tasol wanem samting stika i mas mekim. Ol seksen aninit i stori long dispela disisen olsem em i save kamap long ol 'pre-prodaksen projek, wantaim ol spesifik 'chip', wanpela ful tebol bilong skelim, wanpela 'anti-'giaman 'deep dive', na wanpela 'pre-oda seklis.

 

Kwikpela bekim: NTAG o MIFARE?

Yusim dispela olsem wanpela hariap stating poin, na bihain konfemim ol ditel i go daun.

Olsem wanpela rul bilong thumb: sapos projek i stap long fon, NTAG i hariap na i no gat bikpela pe long putim. Sapos em i dipen long ol rida, ol ki, ol tok orait, o ol seif transeksen, MIFARE, planti taim DESFire, em i gutpela rot.

 

Faivpela askim long askim pastaim long yu makim wanpela 'chip'

Planti hevi bilong "rongpela 'chip'" i save kamap taim yu makim ol 'hardware' pastaim long ol i klia long yusim bilong en. Tingim dispela 5-pela askim pastaim, na bekim bilong en bai kamap klia.

• Husat i save ritim, wanpela fon o wanpela man i save ritim?Sapos pablik i paitim wantaim fon bilong ol yet, yusim NTAG. Sapos wanpela 'fixed reader', 'controller', o 'turnstile' i skenim, yusim MIFARE.
• Yu nidim hamas sekyuriti?Long opim infomesen tasol i nidim standet NTAG tasol. Cryptographic, server-verifiable authentication points to NTAG424 DNA. Enkripted akses o stored veliu poin i go long MIFARE DESFire.
• Hamas data dispela 'chip' i mas holim?Wanpela URL tasol i fit gut long NTAG213; planti NDEF rekot o longpela teks i soim NTAG215 o NTAG216.
• Em bai sindaun long wanem hap?Plastik, pepa, na glas i orait, tasol ain i save pasim antena, olsem na yu masanti-metal NFC stikawantaim wanpela 'ferrite' leia.
• Wanem volium na baset?Ol bikpela 'consumer rollouts' i save laikim 'cost-'optimized NTAG; ol menesmen kredensel sistem i save karim MIFARE sip na ol kos bilong integresen we i stret long sekyuriti na kontrol.

 

NTAG NFC stika em wanem samting?

NTAG NFC stika i yusim NTAG sip famili bilong NXP na ol i wokim bilong yusim ol smatfon we i no hatwok tumas. Ol i save putim data insait longNDEF fomat we NFC Forum i makim, we i save larim klostu olgeta fon i ritim wanpela 'tag' na mekim samting long en, opim wanpela link, soim teks, sevim wanpela kontek, o kirapim wanpela ap, na i no gat wanpela ap.

Ol komon opsen i no wankain long yusa memori:

• NTAG213i gat samting olsem 144 bait bilong yusa memori. Em i gutpela long wanpela URL o sotpela rekot bilong prodak, na em i stap olsem 'default' bilong planti wok maketing na 'packaging'.
• NTAG215i gat samting olsem 504 bait, em i gutpela taim yu nidim planti NDEF rekot o longpela 'payload'.
• NTAG216i gat samting olsem 888 bait, bilong ol samting we i gat planti rekot.
• NTAG424 DNAi gat 416 bait na AES-128 'cryptography' na wanpela 'tap-'yunik 'authentication message'; em i bilong sekyuriti na anti-giaman mani na i no bilong ol 'plain link' tasol.

Wanpela gutpela rot bilong skelim sais bilong 'chip': sapos yu wok long enkodim wanpela URL tasol, NTAG213 em inap long olgeta taim, long wanem, wanpela sotpela link i stap aninit long 144-bait mak bilong en. Muv i go antap longNTAG215o NTAG216 taim yu nidim planti rekot (olsem wanpela URL na teks na wanpela rekot bilong ap), wanpela longpela URL wantaim ol 'tracking parameters', o 'headroom' bilong 're-encode bihain.

 

Wanem ol stika bilong MIFARE NFC?

MIFARE NFC stika i yusim ol MIFARE chips bilong NXP, we i bosim akses kontrol, pablik trenspot, tiket, membasip, na 'closed-loop peimen. Taim yumi skelim wantaim NTAG, MIFARE em i sistem-oriented: dispela 'chip' em i bilong wok wantaim ol rida, ol ki, na ol 'backend' sofwet, na i no wanpela fon tasol.

• MIFARE Classic 1K / 4Kem i wanpela 'legacy workhorse' we i stap yet long planti olpela sistem. Em i yusim 'proprietary Crypto-1 cipher, we i gat ol wiknes we ol i bin raitim gut, olsem na em i gutpela long ol 'low-risk o 'legacy-compatible deployments tasol i no long ol nupela hai-sekyuriti projek. Long kisim bekgraun, lukimMIFARE 1K kad em i wanem samting.
• MIFARE Plusem i wanpela komon rot bilong apgredim long Classic we i save putim AES sekyuriti.
• MIFARE DESFire EV1 / EV2 / EV3em i seif, multi-applikesen lain, yusim AES-128 na tripela-pas mituel autentikesen, olsem ol i stori long enDESFire EV3 dokumentesen bilong NXP. Em i wanpela samting ol i save makim long serios ekses kontrol, transit, na tiket.

Wanpela tok lukaut we i gutpela long tokaut long en pastaim: MIFARE i save kamap olsem wanpela kad, ki fob, o 'wristband' na i no olsem wanpela stika, long wanem, ol dispela sistem i save givim wanpela 'credential' long wanpela man. Olsem ol stika, MIFARE i gutpela moa yet long ol aset o sistem tagging. Sapos projek bilong yu i gat akses- o membasip-, ating yu laik truMIFARE akses kado ol 'fobs' na i no ol 'label'.

 

NTAG na MIFARE NFC stika: sait-long-sait skelim

Dispela tebol i skelim ol 'chips' long ol samting we i save makim wanpela projek.

 

Ol bikpela samting we i no wankain we i save afektim projek bilong yu

 

Smatfon riding: iPhone, Android, NDEF na UID

Pasin bilong yusim fon em i no wanpela samting tasol; em i dipen long wanem samting ol i askim fon long ritim. Planti ol nupela iPhone na Android divais i save ritim wanpela NDEF rekot long wanpela NTAG tag long bekgraun na mekim wok long en, na opim wanpela URL we i no gat wanpela ap i stap. Ritim UID bilong wanpela sip, o ritim sekta o fail data, em i narapela wok we planti taim i nidim wanpela ap o wanpela spesifik rida.

Dispela em i hap we MIFARE Classic i save kamap hevi long ol konsuma projek: sekta data bilong en i no inap long ritim gut long olgeta fon, na sapot bilong iPhone i sot tru, olsem na Classic i save stap wantaim ol dediket rida na i no ol fon bilong pablik. NTAG na DESFire i bihainim ol kain 'tag' bilong NFC Forum, we i mekim ol i kamap gutpela moa. Sapos ol manmeri i yusim fon bilong ol yet, NTAG em i gutpela rot, na em i helpim long kliagut longhau NFC riding i wok long fonpastaim long yu mekim.

 

Sekuriti na autentikesen

Ol standet NTAG21x 'chips' em ol i wokim bilong ol 'open interactions'. Sampela i sapotim 32-bit paswod we inap long pasim man long raitim gen, tasol paswod i no wanpela 'cryptographic authentication', na UID bilong wanpela 'chip', maski em i narakain, ol i ken ritim na i no stap long pruf bilong em yet. Laspela poin em i bikpela samting, long wanem, UID-tasol "verifikasen" em i wanpela bilong ol bikpela rong bilong daunim giaman mani.

Long kisim trupela 'authentication', 'chip' i mas soim em yet long rot bilong 'cryptographic'.NTAG424 DNA bilong NXPyusim AES-128 na kamapim narapela, seva-kod we yu ken sekim long olgeta taim, we i hat tru long klonim. Long sait bilong sistem, MIFARE DESFire i save putim tripela -pas 'mutual authentication' na 'file-level' ki, olsem na kad na rida i save sekim narapela narapela pastaim long wanpela data i muv. Long save long hau dispela i kamap long wok, lukim dispela lukluk longNFC anti-giaman teknoloji.

 

Memori na data straksa

NTAG i yusim wanpela simpol, planti taim linear memori we ol i putim aut long NDEF, na dispela i as na em i isi tru long enkodim ol URL, teks, na ol kontek rekot. MIFARE i yusim wanpela 'structured memory' bilong ol sekta, aplikesen, fail, na ol 'access keys'. Dispela i givim moa kontrol long husat i ken ritim o raitim wanem samting, na tu, ol i mas mekim moa plening, menesmen bilong ol ki, na tes.

 

Integresen bilong sistem na kos

Planti taim ol i ken putim wanpela NTAG projek wantaim wanpelaNFC rida na rait: putim URL, putim stika, na ol kastoma i paitim. Wanpela MIFARE projek i save nidim ol 'compatible readers', 'key management', 'backend' sofwet, na ol 'access rules', na tu, ol i mas traim long 'live system'.

Kost i bihainim dispela hevi. Ol samting tru we i save kirapim prais bilong wanpela NFC stika em kain 'chip', sais bilong antena, sabstret (pepa, PET, PVC, o epoksi), printing, sapos ol 'tag' i stap nating o i gat 'pre-encoded, wanem kain 'lamination' o 'lock step', na, long yusim metal, wanpela 'ferrite layer' we ol i putim, olgeta i bungim wantaim namba. Gutpela stia tok em i isi: noken baim MIFARE kompleksiti taim fon i laik opim wanpela URL tasol, na noken traim long ranim sekyua ekses kontrol long wanpela besik NTAG sip.

 

NTAG424 DNA vs MIFARE DESFire bilong daunim giaman mani

Long lukautim bren dispela em i bikpela samting tru, long wanem, tupela 'chip' i yusim strongpela AES-128 'cryptography' tasol i save stretim ol hevi we i no wankain liklik.

NTAG424 DNA em i bilong ol manmeri i ken sekim. Bikos ol i save kamapim 'authentication code' bilong en long olgeta wan wan 'tap' na sekim long seva bilong yu, wanpela sopa i ken konfemim 'authenticity' wantaim wanpela nomol fon na nogat ap, na wankain 'tap' inap long kirapim maketing o rejistresen. Em i tu wanpela rot we i no gat bikpela pe bilong en long kisim bikpela volium bilong 'product authentication'.

MIFARE DESFire em i bilong planti -aplikesen, rida-bes ekosistem olsem 'access', 'transit', na 'stored value', na em i gutpela samting taim 'secure credential' tu i mas mekim ol dispela wok. Long 'pure consumer product verification' em i save kisim moa long wanem samting yu nidim; long wanpela 'credential' we i mas stap insait long wanpela 'access' o 'payment system' na tu i mas gat wanpela 'authentication function', em i fit gut.

Disisen i stap long wanpela lain tasol: makim NTAG424 DNA bilong lukautim 'brand' bilong ol manmeri, na DESFire taim 'authentication' i mas stap wantaim 'access', 'ticketing', o 'payment' insait long wankain 'managed system'. Maski wanem rot, noken dipen long wanpela UID sekim tasol, long wanem, dispela em i aidentifikesen, i no autentikesen.

 

Yu mas makim long aplikesen

Bilongol maketing kempen na ol smatpela posta, NTAG213 i save lukautim ol URL bilong opim 'tap-to-, daunlodim ol ap, na ol pes bilong kempen long gutpela na gutpela rot. Bilongsmatpela paket na infomesen bilong prodakolsem ol buk, rejistresen bilong waranti, na ol samting bilong bren, NTAG213 i karamapim ol besik link, wantaim NTAG216 taim yu nidim moa rum.

Bilongtok tru bilong prodak na anti-giaman, yusim NTAG424 DNA, o DESFire insait long wanpela bikpela seif sistem, na noken yusim wanpela 'static-URL chip tasol. Bilongakses kontrololsem ol dua, wokman ID, ol rum bilong hotel, na ol eria we i gat tambu, MIFARE DESFire o wanpela 'chip' we i wankain olsem sistem we i stap pinis em i samting we i save kamap, planti taim ol i save givim olsem ol kad o fob na i no olsem ol stika. Bilongbaim tiket, membasip, na ol iven, MIFARE em i gutpela samting, na 'credential' em i save kamapRFID hanbeno kad na i no wanpela lebol. Bilongsimpol aset aidentifikesen, NTAG213 em i inap sapos sistem i no givim wanpela MIFARE sip.

 

Wanem taim yu no ken yusim NTAG, na wanem taim yu no ken yusim MIFARE

Noken NTAGtaim yu nidim 'cryptographic access control', 'stored value' o 'payment', ol 'multi-application management credentials', o ol 'fine-grained backend permissions. Em i teritori bilong DESFire.

Noken MIFARE, moa yet Klasik, taim mak bilong yu em i wanpela simpol, bikpela-skel fon tap-long-URL ekspiriens, taim odiens bilong yu i stap long ol iPhone na yu bai dipen long ol Klasik sekta rid, o taim yu laikim liklik pe na simpol enkoding. Long ol dispela taim NTAG i save hariap, i no gat bikpela pe, na ol i ken save long en.

 

Ol rong we planti man i save mekim taim ol i makim ol NFC stika

1.  

2. Mi makim MIFARE bikos em i luk olsem em i seif moa.

3. Dispela 'chip' tasol i no inap long kamapim sekyuriti; yu nidim tu gutpela menesmen bilong ol ki, 'reader compatibility', na ol 'access rules'. Wanpela DESFire sistem we i no stret em i no seif moa long wanpela NTAG we i gat gutpela 'scoped'.

Ol askim we ol i save askim planti taim

 

Ol stika bilong MIFARE inap wok wantaim wanpela iPhone?

Em i dipen long 'chip'. MIFARE DESFire na NTAG, we ol iPhone i save tingim olsem ol standet NFC Forum tag, i gat gutpela sapot, tasol MIFARE Classic sekta data i no inap long ritim gut long ol iPhone, olsem na ol i save yusim Classic wantaim ol dediket rida na i no ol konsuma fon. Long wanpela fon-namba wan projek, NTAG em i gutpela rot bilong makim.

 

NTAG i seif?

Ol standet NTAG21x 'chips' em ol i wokim bilong ol 'open interactions' na i gat wanpela 'optional password' tasol, we i no strongpela 'authentication'. Sapos yu nidim sekyuriti, NTAG424 DNA i save putim AES-128 na wanpela 'tap-unique' toksave we wanpela seva i ken sekim, we i strong tru long 'product authentication'.

 

Wanem NFC stika i gutpela long stopim giaman mani?

NTAG424 DNA em i nambawan samting bilong lukautim bren bilong ol manmeri, long wanem, ol manmeri i ken sekim wanpela prodak wantaim wanpela nomol fon. MIFARE DESFire i stret long ol keis we wankain sekyua kredensiel i mas lukautim tu akses o pemen. Wanpela UID sekim tasol i no inap long daunim giaman mani.

 

NTAG213 inap long URL bilong mi?

Long wanpela URL tasol, klostu olgeta taim yes, bikos wanpela sotpela link i save fit gut insait long 144 bait bilong yusa memori bilong NTAG213. Go antap long NTAG215 o NTAG216 sapos yu nidim planti NDEF rekot, wanpela longpela URL wantaim ol 'tracking parameters', o moa 'headroom'.

 

Bilong wanem NFC stika bilong mi i no inap ritim long wanpela metal pes?

Metal i save rausim 'standard NFC antena' na pulim 'field', olsem na wanpela nomol stika i no save ritim taim em i pas long metal. Yusim wanpela anti-metal NFC stika wantaim wanpela ferrite leia, na konfemim pefomens long pes bilong yu yet taim yu kisim sempel.

 

Mi mas odarim ol NFC stika we i no gat samting o ol stika we i stap pinis?

Ol 'blank tag' i givim yu sans long putim 'encode' insait long-haus; ol 'pre-encoded tags i save sevim taim long skel tasol yu mas pasim ol konten na rekodim ol kain long fran. Long ol 'dynamic content', askim long ol 'rewritable tags' na sapos 'chip' bai pas bihain long yu 'encoding'.

 

As tingting

Yu mas makim NTAG long namba wan wok bilong fon olsem maketing, smat paket, infomesen bilong prodak, na simpol aidentifikesen, na makim MIFARE, planti taim DESFire, taim stika i hap bilong wanpela seif sistem wantaim ol rida, ki, na tok orait.
