Π Isu takajairana neRFID tag inotitenderedza tisingaonekwe muhupenyu hwemazuva ese. Nhasi isu ticharamba tichinzwisisa kushandiswa kwemazuva ese kwema tag uye tarisa ma tag akagadzirwa muChina.
Foreword
Munguva Handina kukundikana kutora mukana wekushanyira makambani anogadzira RFID tags yemabasa akasiyana-siyana: kubva pabhanari yekupinda tikiti kuenda kukonsati kune kuzvikuvadza ma tags ekumaka zvinhu zvakakosha.
Somuenzaniso, ndakaenda kuhofisi kunze kweShenzhen.
Iyo assortment yemaki, sezvavanotaura, kune ese kuravira uye ruvara:
Nenzira, kana iwe uchida kushandira pamwe nekambani iyi, saka nguva dzose akagadzirira kukubatsira.
Tags kubva kuMiddle Kingdom
Kazhinji, ndakakumbira samples, pakati pawo aive ese ma tag aine machipisi eChinese chete nema tag ane NXP chips. Nezvekupedzisira, zvese zviri pachena; mutungamiri muRFID chip musika uye trendsetter asvika pamakumbo ayo akarovera muChina. Ngatitange navo.
Mune imwe label paive nemukurumbira wepasirese yekare, yakanaka uye yakaedzwa nguva (kubvira 2009) MIFARE chip - CUL1V2.
Mukubwinya kwayo kwese :
Iyo HD vhezheni
Asi mune imwe tag kopi inosetsa kubva kuNXP yakawanikwa - NT2H1V0B, zvinyorwa zvinogona kuwanikwa. . Ehe, vakomana vanobva kuNXP vachiri ma cryptographer; mamaki pane chip akati siyanei nezvinoratidzwa pane chip.
Yakakura, yakaoma, NXP ... Inenge 1 mm kureba!
LM (kuruboshwe) uye OM (kurudyi) mifananidzo pa50x magnification.
Unogona kudhawunirodha mufananidzo weHD
Uye NFC Reader data:
Imwe tag inoparadza yakatakurwa ne NT2TTVAO chip, yakagadzirwawo neNXP, iyo, zvinosuruvarisa, handina kuwana zvinyorwa. Unogona kubatsira here?
Hongu, hongu, iyi diki yekuwedzera yeantenna ndiyo chikamu icho kuparadzwa kwayo kunoiuraya uye haibvumiri tagi kuverengwa. Ichave yakakosha kana iwe uchida kuteedzera, semuenzaniso, kana chigadzirwa chakavhurwa kana kwete.

Uye, hongu, iyo icing pakeke rekuvhura maChinese RFIDs yaive tag ine yakasarudzika Chinese chip.
Sezvo chip ichi chakagadzirwa kuChina, googling zvinyorwa hazvina kuburitsa chero mhedzisiro, kunyangwe zvingave zvinonakidza kuona izvo zvakasvibirira Chinese shasha yakaisa mukati meiyi chip. Semuyenzaniso, ndeapi matatu mapedhi mahombe ari mukona yezasi yekuruboshwe anoshandiswa: kungoyedza kana kuridza alarm yakangwara?

Uye pakupedzisira, imwe data shoma kubva kuNFC Reader nezve iyi tag uye chip:
Pane mhedziso
Muzvikamu zviviri, takatarisa maRFID tag anoshandiswa muhupenyu hwemazuva ese, logistics uye pakutakura zvinhu. Sezvatinoona, kushandiswa kwakapararira uye kudzikiswa kwemitengo kunoenderana neimwe chip yakapusa kwaita kuti zvikwanise kutanga kuunzwa kweRFID uko makore mashanu chete apfuura zvaiita sezvisina kunaka mune zvehupfumi. Kutevera kuwedzera uku, kuunzwa kwakapararira kweautomation kwakatanga - ndine chokwadi, semuenzaniso, kuti magirazi angu ari mubhokisi rine RFID mamaki. Ivo vakabva kune semi-otomatiki kana kunyange automatic warehouse. Mukutenderera uku kwekupa uye kudiwa kwema tag anoraswa, "asiri echinyakare" vagadziri vakaonekwawo, senge isinganzwisisike yeChinese Noname, iyo inogadzira yayo MIFARE machipisi.
Ini ndinofunga kuti muchikamu chinotevera tichabata pamusoro pechinyorwa cheakadzivirirwa machipisi uye maitiro ekutarisa pasi pemetallization layer.
Usakanganwa kunyoresa kune : Hazvina kuoma kwauri - ndinofara!
Uye hongu, ndapota nyorera kwandiri nezve chero kukanganisa kwakaonekwa murugwaro.
