Isikhokelo esiBanzi kwi-RFID Card Technology kunye nezicelo ezitsha

Kweli hlabathi{0}elikhawulezayo ledijithali, amashishini ahlala efuna iindlela zokuphucula ukusebenza kakuhle, ukhuseleko kunye nokuzibandakanya kwabathengi. Obunye ubuchwephesha obutshintshe kakhulu kwimizi-mveliso eyahlukeneyo yi-RFID (Isazisi seRadio Frequency). Ukusuka kwiinkqubo zokulawula ukufikelela kwizixhobo zentengiso, amakhadi eRFID angundoqo wolu tshintsho. Eli nqaku liza kungena kwihlabathi lamakhadi e-RFID, ukuhlola iintlobo zabo ezahlukeneyo ezibandakanya i-125kHz kunye ne-13.56MHz, njengemodeli ye-T5577, kunye nokuxoxa ngendlela amashishini anokubetha ngayo ukulinganisela ukufikelela ekukhuleni. Siza kuphinda sidibane namakhadi ezinto ezenzelwe wena, i-eco{8}}amakhadi enkuni anobubele, kunye namakhadi ophononongo lwe-NFC kaGoogle, aluncedo ekukhuthazeni amashishini akwi-intanethi. Nokuba ungumnini weshishini, umntu othanda itekhnoloji, okanye umntu onethemba lokudibanisa izisombululo ezikrelekrele, esi sikhokelo siya kubonelela ngeembono ezixabisekileyo kunye neengcebiso ezisebenzayo ezisebenza ngokulula.

Ukuqonda i-RFID Card Technology: 125kHz vs. 13.56MHz

Amakhadi e-RFID asebenza kwiifrikhwensi ezahlukeneyo. Ifrikhwensi nganye inesicelo sayo esithile.125kHz amakhadi RFIDziqhele ukusetyenziswa kulawulo lofikelelo olusisiseko kunye neenkqubo zokusondelelana. Zithembekile kwaye zineendleko-ezisebenzayo, kwaye zifanelekile kwiindawo ezifuna izicelo ezilula ze-ID, ezifana neenkqubo zofikelelo lwabasebenzi okanye amakhadi asehotele. La makhadi abandakanya umgangatho we-em4100, owaziwa ngokuhlala kwawo kunye nokulula ukusetyenziswa.

 

Kwelinye icala, i13.56MHz RFID ikhadiinikeza ukusebenza okukhulu kunye nokhuseleko. Le frikhwensi ixhasa iiprothokholi eziphucuke ngakumbi ezifana neMifare (umzekelo, iMifare Classic, iMifare DesFire), esetyenziswa kakhulu kuthutho lukawonke-wonke, iinkqubo zokuhlawula, kunye nolawulo lofikelelo lokhuseleko. Itekhnoloji ye-Mifare ixhasa i-encryption kunye ne-memory partitions, iyenza ilungele iimeko ezahlukeneyo zesicelo. Olunye uhlobo oludumileyo likhadi le-T5577, elinokuhlelwa ngokutsha kwaye lisebenza ngeendlela ezininzi. Ihlala isetyenziselwa izisombululo ezilungiselelweyo apho ukuguquguquka kubalulekile. La makhadi enziwa ngePVC okanye ngemathiriyeli yeclamshell ukuqinisekisa ubukhulu kunye nokuqina okwaneleyo-ukusetyenziswa kwexesha elide.

 

Kwishishini, ukukhetha i-frequency efanelekileyo kuxhomekeke kwizinto ezifana neemfuno zokhuseleko, umgama wokufunda, kunye nokuhambelana neenkqubo ezikhoyo. Ngokomzekelo, aikhadi elikufutshaneesekwe kwi-125kHz inokwanela iofisi encinci, kodwa ishishini elikhulu linokufuna ukhuseleko olongeziweyo ngekhadi leMifare le-13.56MHz.

 

Ngaphaya koLawulo lokuFikelela: Izicelo zoRhwebo kunye nokuKhula koShishino

Itekhnoloji yeRFID ayingokhuseleko kuphela; sisixhobo esinamandla sokuqhuba ukukhula kweshishini. Iinkampani ezininzi ngoku zisebenzisa amakhadi e-RFID ekuthengiseni nasekubandakanyeni abathengi. Njengokuba,NFC Google amakhadi ophononongoziya zithandwa kakhulu phakathi kwabathengisi kunye nababoneleli ngeenkonzo. Xa aba bathengi bechukumisa amakhadi ngee-smartphones zabo, kubakhokelela ngokuthe ngqo ukuba bashiye uphononongo kuGoogle, ngaloo ndlela bephucula ukubonakala kwe-intanethi kunye nokuthembeka. Esi sicwangciso silula nesisebenzayo sinokukhokelela ekuthengisweni okuphezulu kunye nokwandisa isidima, ngakumbi kumashishini okanye kubathengisi beSitolo sam sikaGoogle.

 

Okubaluleke ngakumbi, amakhadi e-RFID eza ngeendlela ezahlukeneyo kwaye akaphelelanga nje kumakhadi e-PVC aqhelekileyo. Iifobhu ezingundoqo kunye neeleyibhile zezinye iindlela ezifanelekileyo ezifanelekileyo kwiikhonkco ezingundoqo kunye nokulandelwa kwe-asethi. Zisetyenziswa ngokubanzi kumaziko empilo, iindawo zokupaka kunye nolawulo lwempahla. Ngokudibanisa ezi kunyeAbafundi bekhadi le-RFID, amashishini anokwenza amava angenamthungo, njengeenkqubo zokubala ngokuzenzekelayo kunye neenkqubo zobulungu ezizimeleyo.

 

Ukwenza wena kunye noZinzo: UkuPhakamisa koBugcisa kunye ne-Eco{0}}Amakhadi aHloniphekileyo

Ngexesha apho ukwenza ngokwezifiso kunye nozinzo zizinto eziphambili kubathengi, itekhnoloji yeRFID ihambelana ngokugqibeleleyo. Iikhadi lobugcisa bomntuidibanisa zombini iimpawu zoyilo kunye nokusebenza. Ishishini ngoku libonelela ngamakhadi e-RFID enziweyo anokuthi ayilwe ngeelogo, iipateni, kunye nemifanekiso ukuze ilungele ngokugqibeleleyo ulawulo lofikelelo lwebhrendi, amatikiti esiganeko, okanye ukuhanjiswa kwentengiso. Xa esetyenziswa ngokubambisana nobuchwepheshe be-NFC, la makhadi anokuthi adityaniswe nomxholo wedijithali onjengewebhusayithi okanye iiprofayili zemidiya yoluntu, ngaloo ndlela ephucula ukubandakanyeka komsebenzisi.

 

Ngokufanayo, ihambelana nokusingqongileyoamakhadi RFID ngamaplangakancinci kancinci ziye zibe lukhetho oludumileyo lweempawu ezinolwazi lokusingqongileyo. La makhadi enziwe ngezinto ezifana ne-bamboo okanye iinkuni ezinokuphinda zisetyenziswe. Banikezela ngemeko eyodwa kunye{2}}nomgangatho ophezulu wokuziva ngelixa behlisa inkunkuma yeplastiki. Zithandwa kakhulu kwiindawo ezinjengendawo yokuhlala, ukutya kunye nokuthengisa. Kwezi zicelo, ukunyuswa kophawu kunye nokuzinza kukwinqanaba elifanayo nokutsala abathengi banamhlanje.

 

Ukudibanisa iiNkqubo zeRFID: Abafundi kunye naNgaphaya

Ukuze usebenzise ngokupheleleyo amakhadi eRFID, amashishini adla ngokufuna abafundi abahambelanayo. Ezi zixhobo zivela kubafundi be-USB abalula ukuya kwiinkqubo zenethiwekhi ezinzima. Ukusetyenziswa kwabo okudibeneyo kwenza ukuxhomekeka okuqinileyo kwisicelo. Umzekelo, indawo yokutyela inokusebenzisa iincwadi zokufunda ezisisiseko ukulandelela ukubakho kwabasebenzi, ngelixa umzi-mveliso unokufuna iincwadi zemizi-mveliso-ezenzelwe ngokukodwa izixhobo zokulandela umkhondo. Isitshixo ekuqinisekiseni ukuba ikhadi liyahambelana nomfundi ilele frequency kunye neprotocol (umz., 125kHz abafundi amakhadi 125kHz). Le ndibaniselwano ayiphuculi nje ukusebenza kakuhle kodwa ikwabonelela ngesigqibo esixabisekileyo{10}}sokwenza idatha enokuhlalutywa kwaye isetyenziswe ukwenza izigqibo.

 

Isiphelo: Yamkela iRFID yeKamva{0}}Izisombululo zeShishini eziBubungqina

Itekhnoloji yekhadi le-RFID kunye namakhadi ayo e-Mifare ukusuka kwi-125kHz ukuya kwi-13.56MHz inikezela ngamathuba orhwebo angenasiphelo. Nokuba kungokomeleza ukhuseleko ngokusetyenziswa kwamakhadi ashinyeneyo eclamshell, ukuphucula uphononongo ngamakhadi ophononongo lwe-NFC kaGoogle, okanye ngokufaka amakhadi omthi azinzileyo, umda wesicelo wawo ubanzi. Ngokuqonda ezi ndlela zokhetho kunye nokuzidibanisa nabafundi abafanelekileyo, inkampani inokuhlengahlengisa imisebenzi yayo, iphucule ukuzibandakanya kwabathengi ngelixa igcina inkqubela-phambili yayo kwimarike yokhuphiswano.
