ST25TV ochungechungeni lwamathegi e-NFC
https://www.st.com/en/nfc/st25tv-series-nfc-tags.html
Uhlobo lwe-ST25TV 5 I-NFC tag IC iyisixazululo sokuqala sokuhlanganisa ukusebenziseka kalula kokuxhumana okude ngokwe-ISO/IEC 15693 izinga elinamandla okuthola ukuphazamisa. Uma kuqhathaniswa nezinye izinhlobo zamathegi e-NFC, Amathegi e-ST25TV afundeka kalula, ngaleyo ndlela kuthuthukiswe ulwazi lomsebenzisi ekwakhiweni komkhiqizo. Abaklami bomkhiqizo nabakhiqizi manje bangasebenzisa omaka be-NFC abancane nezitikha eziphephe kakhudlwana futhi ezifakeka kalula ukuze kuthuthukiswe ukusebenzisana kwamakhasimende.. Lesi sixazululo esiyingqayizivele singasetshenziswa kuwo wonke umjikelezo wokuphila womkhiqizo, ukusuka endaweni yokukhiqiza kuya ekusebenzelaneni kwabathengi endaweni yokuthengisa nangale kwalokho. Inikeza izimpahla zansuku zonke zabathengi impilo yedijithali.
Uchungechunge lwe-ST25TV lunikeza amathegi anenkumbulo engu-512-bit noma engu-2-Kbit, kufaka phakathi isevisi yemiyalezo ye-NDEF ezenzakalelayo. Ivumela ithegi ukuthi iphendule ngokuqukethwe okukhiqizwa ngamandla uma icushwa umsebenzisi wokugcina kanye neselula yakhe ye-NFC elula. “kampompi”. Lobu buchwepheshe bubizwa nge-Augmented NDEF.
Omaka be-ST25TV bangasetshenziselwa ukuvikela umkhiqizo ophethwe ngamafu, njengokutholwa kokulwa nomgunyathi/ukuphazamisa ezindaweni ezisetshenziswayo ezahlukahlukene ezihlanganisa iwayini nemimoya, Amakhemikhali, nezimpahla zikanokusho. Angasetshenziswa futhi nezifundi ezikude ze-HF RFID ukuze zihlonzwe umkhiqizo, logistics, kanye nezinhlelo zokusebenza zokulandeleka.
