Ii-keyfob ze-RFID zizixhobo ezincinci neziphathekayo ezisebenzisa itekhnoloji ye-Radio Frequency Identification (RFID) ukubonelela ngolawulo lokufikelela olukhuselekileyo kunye nokuchongwa. Ziqulathe itshiphu encinci kunye ne-antenna, ezinxibelelana nabafundi be-RFID besebenzisa amaza erediyo. Xa i-keychain ibekwe kufutshane ne-RFID reader, idlulisela ulwazi lwayo olukhethekileyo lokuchongwa, ivumela ukufikelela okanye ukwenza isenzo, njengokuvula ucango okanye ukuvula inkqubo.

Iikeychain zeRFID zihlala zisetyenziselwa ukungena ngaphandle kokuthintana kwiiofisi, iiflethi, kunye nezakhiwo ezikhuselekileyo, kunye neenkqubo zothutho lukawonke-wonke okanye zokuhlawula. Zibonelela ngenye indlela elula nekhuselekileyo kunezitshixo okanye amakhadi emveli, nto leyo enciphisa umngcipheko wokubiwa okanye ukulahleka. Iikeychain zikwaqinile, zikhaphukhaphu, kwaye kulula ukuziphatha, nto leyo ezenza zilungele ukusetyenziswa imihla ngemihla.

Lilonke, ii-keychains ze-RFID zibonelela ngesisombululo esilula kodwa esisebenzayo sokufikelela ngokukhuselekileyo, nto leyo ezenza zibe yinxalenye ebalulekileyo yeenkqubo zokhuseleko zanamhlanje.
