Π Sajwayelana namathegi e-RFID asizungezile ngokungabonakali ekuphileni kwansuku zonke. Namuhla sizoqhubeka nokuqonda ukusetshenziswa kwansuku zonke kwamathegi futhi sibheke omaka abenziwe e-China.
Isibikezelo
Ngesikhathi Angizange ngihluleke ukuthatha ithuba lokuvakashela izinkampani ezikhiqiza omaka be-RFID bemisebenzi ehlukahlukene: kusukela ethikithini lokungena elivinjelwe ukuya ekhonsathini kuya kumathegi azilimazayo okumaka izimpahla ezibalulekile.
Ngokwesibonelo, ngaya ehhovisi emaphethelweni eShenzhen.
I-assortment yamathegi, njengoba besho, kukho konke ukunambitheka nombala:
By the way, uma unentshisekelo yokubambisana nale nkampani, ke njalo ekulungele ukukusiza.
Omaka abavela e-Middle Kingdom
Sekukonke, ngicele amasampula, phakathi kwawo omabili amathegi anama-chips namathegi aseShayina anama-NXP chips. Ngalokhu kwakamuva, yonke into icacile; umholi emakethe ye-chip RFID kanye ne-trendsetter usefinyelele izidladla zakhe ezinezidladla eChina. Ake siqale ngabo.
Kwenye ilebula kwakukhona endala edumile emhlabeni wonke, enhle futhi ehlolwe isikhathi (kusukela ngo-2009) i-chip ye-MIFARE - CUL1V2.
Enkazimulweni yayo yonke :
Inguqulo yayo ye-HD
Kodwa kwenye ithegi kwatholakala ikhophi ehlekisayo evela ku-NXP - NT2H1V0B, imibhalo engatholakala . Yebo, abafana abavela ku-NXP basengababhali be-cryptographer; izimpawu ku-chip zihluke ngandlela thile kulokho okukhonjiswe ku-chip.
Enkulu, eyinkimbinkimbi, i-NXP... Cishe i-1 mm ubude!
Izithombe ze-LM (kwesokunxele) kanye ne-OM (kwesokudla) ekukhuliseni okungu-50x.
Ungalanda isithombe se-HD
Nedatha ye-NFC Reader:
Enye ithegi ebhubhisayo ilayishwe nge-chip ye-NT2TTVAO, eyenziwe nayo yi-NXP, lapho, ngeshwa, angikwazanga ukuthola imibhalo. Ungakwazi ukusiza?
Yebo, yebo, lesi sithasiselo esincane se-antenna siyingxenye ebulawa ukubhujiswa kwayo futhi akuvumeli ukuthi ithegi ifundwe. Kuzofaneleka uma udinga ukulandelela, isibonelo, ukuthi ngabe umkhiqizo uvuliwe noma cha.
Izithombe ze-LM (kwesokunxele) kanye ne-OM (kwesokudla) ekukhuliseni okungu-50x.
Ungalanda isithombe se-HD
Futhi, kunjalo, uqweqwe lwekhekhe lokuvula ama-RFID aseShayina kwakuwumaka onechip yesiShayina kuphela.
Njengoba i-chip yenziwe e-China, ukuhlola imibhalo akuzange kuveze imiphumela, nakuba kungajabulisa ukubona ukuthi uhlakanipho lwamaShayina olufiphele lubeke ini ngaphakathi kwale chip. Isibonelo, asetshenziselwa ini amaphedi amakhulu angu-3 ekhoneni elingezansi kwesokunxele asetshenziselwa: ukuhlola nje noma i-alamu ehlakaniphile yokuphazamisa?

Futhi ekugcineni, enye idatha encane evela ku-NFC Reader mayelana nale thegi ne-chip:
Esikhundleni isiphetho
Ezingxenyeni ezimbili, sibheke amathegi e-RFID asetshenziswa ekuphileni kwansuku zonke, ukuhlelwa kwezinto kanye nalapho kuthuthwa impahla. Njengoba sibona, ukusetshenziswa okusabalele kanye nokwehliswa okuhambisanayo kwamanani ku-chip eyodwa elula kwenze kwaba nokwenzeka ukuqalisa ukwethulwa kwe-RFID ezindaweni lapho eminyakeni emi-5 nje edlule kwakubonakala kungakhangi kangako ngokomnotho. Ngemva kwalokhu kwandiswa, ukwethulwa okusabalele kokuzenzakalela kwaqala - ngiyaqiniseka, ngokwesibonelo, ukuthi izibuko zami zisebhokisini elinezimpawu ze-RFID. Zazivela esitolo esizishintshayo noma esizenzakalelayo. Kulo mjikelezo wokuhlinzekwa kanye nesidingo samathegi acishe alahlwa, abakhiqizi βabangebona abendabukoβ nabo bavele, njenge-Chinese Noname engaqondakali, eyenza ama-chips ayo e-MIFARE.
Ngicabanga ukuthi engxenyeni elandelayo sizothinta isihloko sama-chips avikelwe nendlela yokubheka ngaphansi kwesendlalelo se-metallization.
Ungakhohlwa ukubhalisa ku : Akunzima kuwe - ngiyajabula!
Futhi yebo, ngicela ungibhalele mayelana nanoma yikuphi ukushiyeka okuphawulwe embhalweni.
