Ama-keyfob e-RFID angamadivayisi amancane, aphathekayo asebenzisa ubuchwepheshe be-Radio Frequency Identification (RFID) ukuhlinzeka ngokulawula ukufinyelela okuphephile kanye nokuhlonza. Aqukethe i-chip encane kanye ne-antenna, exhumana nabafundi be-RFID besebenzisa amaza omsakazo. Uma i-keychain ibekwe eduze kwesifundi se-RFID, idlulisela ulwazi lwayo oluhlukile lokuhlonza, ivumela ukufinyelela noma ukuqala isenzo, njengokuvula umnyango noma ukuvula uhlelo.

Amaketanga okhiye e-RFID avame ukusetshenziselwa ukungena ngaphandle kokuthinta emahhovisi, emafulethini, nasezindlini eziphephile, kanye nasezinhlelweni zokuhamba zomphakathi noma zokukhokha. Anikeza enye indlela elula nephephile esikhundleni sezikhiye noma amakhadi endabuko, okunciphisa ingozi yokwebiwa noma yokulahleka. Amaketanga okhiye nawo aqinile, alula, futhi kulula ukuwaphatha, okwenza afaneleke ukusetshenziswa kwansuku zonke.

Sekukonke, amaketanga okhiye e-RFID ahlinzeka ngesisombululo esilula kodwa esisebenzayo sokufinyelela okuphephile, okwenza abe yingxenye ebalulekile yezinhlelo zokuphepha zanamuhla.
