Umhlahlandlela Wamakhadi Ebheji e-RFID: Izinto, Ukuphrinta Nokubhala Ngekhodi

Amabheji Ekhadi Namakhadi Ebheji: Umhlahlandlela Womthengi Ongokoqobo Wezinto Ezibalulekile, Ukuphrinta, Ukufaka ikhodi, noku-oda

 

 

Lo mhlahlandlela uhlelwe ngendlela abathengi abahlola ngayo amabheji, kusukela kokuthi "iyini le nto" kuya kokuthi "ngiyi-oda kanjani ngaphandle kwezimanga." Ihlanganisa izinto zokwakha, usayizi nomsebenzi wobuciko, umehluko wangempela phakathi kwamaphrinta amabheji, i-RFID kanye nombhalo wekhodi we-NFC ngokujula okwanele ukuze uhambisane nesiqiniseko somfundi, ukuqedwa kokuvikela, izisetshenziswa, ukukhethwa kwabahlinzeki, kanye nentengo yangempela nezikhathi.

 

Liyini ikhadi lebheji, futhi lihluke kanjani kwamanye ama-ID amakhadi?

 

Ikhadi lebheji yinhlangano{0}}ikhadi lokuhlonza elikhishiwe elisetshenziselwa ukuhlonza abasebenzi, izivakashi, osonkontileka, abafundi, noma abahambele umcimbi. Ngokungafani ne-ID-ekhishwe uhulumeni, ikhadi lebheji lakhelwe izidingo zenhlangano eyodwa, ngakho-ke lingakwazi ukuthwala uphawu lwenkampani, isithombe, imininingwane yokufinyelela, ibhakhodi noma ikhodi ye-QR, noma i-chip ye-RFID/NFC eshunyekiwe. Okungenalutho okufanayo kungaba ibheji ye-ID yesisebenzi, iphasi yesivakashi, ikhadi lobulungu, i-ID yesitshudeni, noma ibheji lenkomfa kuye ngokuthi uphrinta ini futhi uyibhale ini ngekhodi kukho.

 

Abantu bavame ukusebenzisa amagama agqagqene, ngakho kuyasiza ukuwahlukanisa. Ithegi yegama imane ibonise igama futhi mhlawumbe inkampani; ayinazo iziqinisekiso. Iphasi yesivakashi iyibheji elifushane-elihlala njalo, elivamise ukuba yiphepha, elinikeza ukufinyelela kwesikhashana esakhiweni. Ikhadi lokufinyelela lichazwa yi-chip yalo kunokuphrinta kwalo, futhi ukuphrinta kungase kungabi nalutho. Ibheji yesithombe inoma yikuphi kwalokhu okungenhla okunesithombe somnikazi wekhadi esingezwe ukuze kuqinisekiswe okubonakalayo. Empeleni umugqa obaluleke kakhulu owe-elekthronikhi: ibheji-ephrintiwe kuphela efakazela ubuwena kumuntu, kuyilapho i-chip{7}}ephethe ibheji ifakazela lokho kumfundi. Uma ukala ikhadi le-chip yothintana naye ekhadini le-plain proximity, kufanelekile ukuliqondaukuthi amakhadi e-IC nama-ID ahluke kanjaningaphambi kokuthi uzibophezele kufomethi, ngoba uhlobo lwe-chip lushayela kokubili izindleko nokuphepha.

 

Iyiphi impahla yebheji okufanele uyikhethe?

 

Ukukhetha kwezinto kuya ngokuthi ibheji lizophathwa kanjani, lizophrintwa kanjani, nokuthi lidinga ukuhlala isikhathi esingakanani. Izinhlangano eziningi ezingaphezulu{1}}zicacisa lapha, zikhokhela ukujiya noma ukulaliswa ezingakudingi. Ithebula elingezansi liyisiqalo; amanothi ngemva kwawo yilapho izinqumo zangempela zihlala khona.

 

 

Ngokwazi kwethu, i-PVC evamile engu-30 mil iyimpendulo elungile kuningi elikhulu lamahhovisi kanye{1}}nezinhlelo zokulawula ukufinyelela, futhi izicelo eziningi "zesidinga okuthile okuqinile" zimayelana nokugqokwa okusemngceleni okungase kuxazululwe ngenani eliphansi kunesitoko esijiyile. Abakhiqizi abaningi batusa ukwenyuka kufikela ku-40 mil kuphela uma amabheji ebhekene nokuhlukunyezwa kwangempela kwemboni, ngoba ukujiya okwengeziwe kuphakamisa izindleko ngaphandle kokwenza indawo ephrintiwe ibukeke kangcono. Ngezinhlelo eziphrinta ama-ID esithombe ngevolumu, evamileAmakhadi e-PVC RFIDphatha kokubili umsebenzi wobuciko kanye ne-chip eshumekiwe endaweni engenalutho eyodwa.

 

 

Osayizi bebheji nemininingwane yomsebenzi wobuciko evimbela ukuphrinta kabusha

 

Ibheji elivame kakhulu lilandela ifomethi ye-ISO ID-1 / CR80 kokuthi 85.6 × 54 mm, ubukhulu obufanayo nekhadi lesikweletu. Lokho kumiswa akunangqondo: kuchazwa yi-ISO/IEC 7810, ebeka izici ezibonakalayo, ubukhulu, kanye nezimfuneko zokuqina zamakhadi okuhlonza ukuze asebenze kubabambi, amaphrinta, kanye nabafundi emhlabeni wonke. Ukunamathela ku-CR80 kusho ukuthi amabheji akho alingana-nezinsiza zeshalofu nezishumeki ngaphandle kwamathuluzi angokwezifiso.

 

Amanye amafomethi akhona emisebenzi ethile: CR79 (83.9 × 51 mm) okunamathelayo-amakhadi angemuva anamathela ekhadini eliseduze, amabheji omcimbi amakhulu (cishe ngo-100 × 150 mm) wezingqungquthela lapho igama kufanele lifundeke ekamelweni lonke, namabheji amancane e-VIP noma ithokheni. Izimo ezisikiwe{7}ezisikiwe ziyatholakala kodwa engeza izindleko zamathuluzi nesikhathi sokuhola, ngakho zigcinele izingcezu zokuphromotha kunomazisi wansuku zonke.

 

Ngomsebenzi wobuciko, ukucaciswa okuvimbela ngempela ukuphrinta kabusha yilezi: setha ikhanvasi kusayizi wekhadi eliqediwe, engeza u-3 mm wokopha ukuze imidwebo engemuva iphume onqenqemeni lokunquma, gcina umbhalo namalogo endaweni ephephile engu-2-3 mm ngaphakathi kokusikwa, sebenza ku-300 DPI ku-CMYK, bese uthekelisa i-PDF enamagama achaziwe nezithombe zishunyekiwe. Uhlu lwedatha olufushane-luvamise ukufaka igama, isithombe, umnyango, isihloko, ilogo yenkampani, ibhakhodi noma ikhodi ye-QR, kanye nenombolo ye-chip lapho kufanele khona.

 

Amabheji ezithombe anezidingo zawo ezithulile ezitholwa abathengi kuphela ngemva kwenqwaba embi: thwebula endaweni engemuva ethafeni, ekhanyiswe ngokulinganayo, gwema ithunzi elisindayo, futhi unikeze izithombe ngokulungiswa okusabukeka kubukhali ngosayizi wokuphrinta kunesithonjana esikhishwe kuhlelo lokusebenza lengxoxo. Amaphutha edizayini avelayo esiwabonayo ayabikezelwa, ngakho-ke kufanelekile ukuwahlola ngaphambi kokuthi{1}}uvale:

• Izithombe{0}}ezinokulungiswa okuphansi ezishintshashintsha ngosayizi wekhadi.
• Amafayela e-RGB athunyelwe kunqubo yokuphrinta ye-CMYK, eshintsha imibala.
• Ukopha okungekho, okushiya ama-slivers amhlophe amancane emaphethelweni ngemva kokusika.
• Amafonti ashiywe{0}engacacisiwe, ngakho aphinde ageleze noma ashintshele esiteshini sokuphrinta.
• Amakhodi e-QR aphushelwe eduze kakhulu onqenqemeni, lapho ukusika kunqamula indawo ethulile.
• Umzimba wombhalo ongaphansi kuka-6 pt, noma umehluko ongemuhle phakathi kombhalo nengemuva.
•  

Ingabe amaphrinta amabheji ahluke kanjani ngempela?

 

"Iphrinta yebheji" ihlanganisa ubuchwepheshe obubili obuhluke ngempela, futhi okubadidayo kulapho kuvela khona izikhalazo eziningi zekhwalithi yokuphrinta. Inketho ishayela ikhwalithi yesithombe kumakhadi e-chip, ukumbozwa konqenqema, izindleko zokusebenza, nokuthi iyunithi idinga ukulungiswa okungakanani.

 

 

Kumaribhoni, ukwakheka kwephaneli yikho okunquma kokubili umbala kanye nesivuno. Iribhoni ye-YMCKO iphethe okuphuzi, oku-magenta, okusacyan, iphaneli ye-resin emnyama, nembondela ecacile, okuyikona konke okudingayo ukuze uthole ibheji-egcwele yombala owodwa{2}}. I-YMCKOK yengeza iphaneli yesibili emnyama ukuze iphrinte emuva, amaribhoni e-monochrome aphatha umbhalo-amakhadi kuphela ngeshibhe kakhulu, futhi imbondela enikelwe noma i-laminate yengeza ukuklwebheka nokuvikela kwe-UV. Isivuno seribhoni, okusho ukuthi mangaki amakhadi ephrinta i-roll eyodwa, inombolo eshayela buthule izindleko zakho ngekhadi ngalinye, ngakho-ke liqhathanise nenani leribhoni kunokuba lizihlukanise.

 

Okucaciswayo okubili abathengisi abacwebezelayo kodwa ochwepheshe benkundla abakhathalelayo umjikelezo wokuhlanza (ama-printheads namarola adinga amakhithi okuhlanza avamile, futhi ukweqa kuvele njengemigqa) kanye nesivinini sokuphrinta sangempela ngaphansi kweribhoni yakho yangempela, hhayi isihloko sesihloko esisodwa{{0}isibalo sombala. Emahhovisi amancane, ukungena-izinga eliqondile{3}}ku-iyunithi yekhadi elineribhoni ye-YMCKO kuningi; amabhizinisi amakhulu nezinhlelo zikahulumeni ezidinga umkhawulo-ukuze{6}}unqenqemeni okukhiphayo kumakhadi ahlakaniphile ngokuvamile zithuthela ekudluliseleni kabusha. Uma ufanisa iphrinta nevolumu yakho nezidingo zokuphepha, ukuhamba kwethu kuvuliweukukhetha iphrinta yekhadiiya ngokujula, futhi ukukhiqizwa kwangaphandle, uchwephesheukuphrinta{0}}kwamakhadi okuhlakaniphileigwema ukuthenga i-hardware isikhathi eside-.

 

Yibuphi ubuchwepheshe bokufaka ikhodi obulingana nesistimu yakho yokufinyelela?

 

Lesi yisigaba lapho iziqondiso ezingajulile zikubiza khona imali, ngoba "i-RFID" akuyona into eyodwa. I-frequency ne-chip oyikhethayo kufanele ifane nabafundi asebevele beseminyango yakho, futhi ukuyenza ingalungile kusho ukushintsha abafundi noma{1}}ukukhipha ikhadi ngalinye. Ukwehlukaniswa okungokoqobo kwenzeka nge-frequency.Izicaciso ezimbalwa ithebula elingakusikisela kuphela.

 

Uma ukala-izindleko zangaphambili nezomjikelezo wempilo zamafrikhwensi wokufinyelela amabili amakhulu, ukuqhathanisa phakathi125 kHz kanye ne-13.56 MHz izifakazeloilona iqembu elithenga kakhulu eleqa futhi elizisola kamuva. Ukuze uthole isithombe esibanzi samakhadi avikelekile, umchazi wethu uvuliweukuthi i-RFID smart card isebenza kanjaniixhuma i-chip kumqondo womfundi. Noma yini oyikhethayo, iqinisekise ngokumelene nokufakiwe kwakhoabafundi bokulawula ukufinyelelaokokuqala, ngoba umfundi, hhayi ikhadi, ubeka imithetho.

 

Ku-NFC ngokuqondile, ukusebenzisana kubuswa Iforamu ye-NFC, -izincazelo zayo zohlobo lwethegi zihlala phezu kwe-ISO/IEC 14443; yingakho ibheji ye-NFC efakwe ikhodi ohlotsheni lwethegi elungile ifundwa ngokuqhubekayo ngama-smartphones ajwayelekile. Amacala amabili ansuku zonke okufanele amemeze: amakhadi okhiye behhotela asasebenzisa umugqa kazibuthe noma u-13.56 MHz, futhi uma lokho kuwuhlelo lwakho lokusebenza, kuyasiza ukuqonda.ukuthi amakhadi okhiye wehhotela asebenza kanjaningaphambi kokukhetha phakathi kwakho kokubili.

 

Ukuqedwa kokuphepha{0}}kwemininingwane yokuqinisekisa ephakeme
