В Sesijwayele omaka be-RFID, abasizungezile ngokungabonakali ekuphileni kwansuku zonke. Namuhla, sizoqhubeka nokuhlola ukusetshenziswa kwansuku zonke komaka futhi sibheke omaka benziwe e-Chinese.
Isibikezelo
Ngesikhathi Ngithathe ithuba lokuvakashela izinkampani ezikhiqiza amathegi e-RFID ezinhlobonhlobo zezinhlelo zokusebenza: kusukela kumathikithi ekhonsathi alula kuya kumathegi azilimazayo okumaka izimpahla ezibalulekile.
Ngokwesibonelo, ngama ngasehhovisi emaphethelweni eShenzhen.
Uhlu lwamathegi, njengoba besho, lufanela konke ukunambitheka nombala:
By the way, uma unentshisekelo yokubambisana nale nkampani, ke njalo ekulungele ukukusiza.
Omaka abavela e-Middle Kingdom
Ngakho-ke, ngicele amasampula, ahlanganisa womabili amathegi anama-chips aseShayina kanye nomaka abanama-NXP chips. Lokhu kwakamuva kusobala: umholi wemakethe ye-chip RFID kanye ne-trendsetter yelule izinzipho zayo eChina. Ake siqale ngabo.
Ithegi eyodwa ibiqukethe i-chip edumile emhlabeni wonke, enhle, futhi ehlolwe isikhathi (kusukela ngo-2009) i-chip ye-MIFARE - CUL1V2.
Kuyo yonke inkazimulo yayo kusukela :
Inguqulo yayo ye-HD
Kodwa kwenye ithegi, kwatholakala isifanekiso esihlekisayo esivela ku-NXP - NT2H1V0B, imibhalo engatholwa Yebo, abafana ku-NXP bangabanye bangempela be-cryptographer; izimpawu ku-chip zihluke kancane kulokho okubhalwe ku-chip.
Kukhulu, kuyinkimbinkimbi, i-NXP-ish… 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 inikwe amandla yi-chip ye-NT2TTVAO, ebuye yenziwe yi-NXP, okwathi, ngeshwa, angizange ngithole noma yimiphi imibhalo. Ungakwazi ukusiza?
Yebo, leso sithasiselo se-antenna siyingxenye okuthi, uma ichithwa, ibulale uthi futhi ivimbele ukuthi umaki ufundwe. Lokhu kuyasiza uma udinga ukulandelela, isibonelo, ukuthi into ivuliwe noma cha.

Futhi, kunjalo, uqweqwe lwekhekhe lomaki we-RFID wase-Chinese oluqhekekayo lwalungamathegi ane-chip yesiShayina kuphela.
Njengoba i-chip yenziwe e-China, i-Googling imibhalo ayizange ibe nemiphumela, nakuba kungajabulisa ukubona ukuthi uhlakanipho lwamaShayina olunomthunzi lubeka ini ngaphakathi kwale chip. Isibonelo, asetshenziselwa ukuthini amaphedi amathathu amakhulu okuxhumana asekhoneni elingezansi kwesokunxele: asetshenziselwa ukuhlola noma i-alamu ehlakaniphile yokuphazamisa?
Izithombe ze-LM (kwesokunxele) kanye ne-OM (kwesokudla) ekukhuliseni okungu-50x.

Ekugcineni, enye idatha encane evela ku-NFC Reader mayelana nale thegi ne-chip:
Esikhundleni isiphetho
Ezingxenyeni ezimbili, sihlole omaka be-RFID abasetshenziswa empilweni yansuku zonke, ukuhlelwa kwezinto, kanye nokuthuthwa kwempahla. Njengoba sibona, ukutholwa okusabalele kanye nokwehliswa okuhambisanayo kwezindleko nge-chip ngayinye elula kuye kwasiza ukuqaliswa kwe-RFID ezindaweni lapho bekuyobonakala kungathandeki ngokomnotho eminyakeni emihlanu edlule. Ngemva kwalokhu kunwetshwa, okuzenzakalelayo sekuqalile ukusetshenziswa yonke indawo—ngokwesibonelo, ngiqinisekile ukuthi izibuko zami zisebhokisini elinomaka be-RFID. Bafika bevela ku-semi-automated noma ngisho ne-automated fullhouse. Kulo mjikelezo wokuhlinzekwa kanye nesidingo samathegi alahlwayo, abakhiqizi "okungebona abendabuko" nabo bavele, njengenkampani engaqondakali yaseShayina i-Noname, 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.
