Ama-keyfobs e-RFID amathuluzi amancane, aphathekayo asebenzisa ubuchwepheshe be-Radio Frequency Identification (RFID) ukuze anikeze ukulawula okuphephile kokufinyelela kanye nokuhlonza. Aqukethe i-chip encane kanye nothi, oluxhumana nabafundi be-RFID kusetshenziswa amaza omsakazo. Uma i-keychain ibekwe eduze nesifundi se-RFID, idlulisela ulwazi lwayo lokuhlonza oluhlukile, oluvumela ukufinyelela noma ukucupha isenzo, njengokuvula umnyango noma ukuvula isistimu.

Okhiye be-RFID bavame ukusetshenziselwa ukungena ngaphandle kokuthinta emahhovisi, ezindlini, nasezindlini ezivikelekile, kanye nasezintweni zokuhamba zomphakathi noma izinhlelo zokukhokha. Banikeza enye indlela elula nevikelekile kokhiye bendabuko noma amakhadi, enciphisa ingcuphe yokweba noma yokulahlekelwa. Amaketango okhiye nawo aqinile, angasindi, futhi kulula ukuwaphatha, okuwenza alungele ukusetshenziswa kwansuku zonke.

Sekukonke, okhiye be-RFID bahlinzeka ngesixazululo esilula kodwa esisebenzayo sokufinyelela okuphephile, okubenza babe yingxenye ebalulekile yezinhlelo zokuphepha zesimanje.
