Ma tag a RFID (Radio Frequency Identification) ndi zida zazing'ono zomwe zimagwiritsa ntchito mafunde a wailesi kufalitsa deta. Amakhala ndi microchip ndi mlongoti, zomwe zimagwirira ntchito limodzi kutumiza chidziwitso kwa owerenga RFID. Mosiyana ndi ma barcode, ma tag a RFID safuna mzere wachindunji wowonera kuti awerengedwe, kuwapangitsa kukhala achangu pakutsata ndi kuyang'anira zinthu.

Ma tag a RFID amagwiritsidwa ntchito m'mafakitale ambiri monga ogulitsa, mayendedwe, zaumoyo, ndi kupanga. Pogulitsa, amathandizira pakuwongolera zinthu, kupewa kuba, komanso kufulumizitsa kulipira. Pazinthu, ma tag a RFID amatsata zomwe zatumizidwa ndi katundu, zomwe zimapangitsa kuti mayendedwe azigwira bwino ntchito.

Pali mitundu iwiri ikuluikulu ya ma tag a RFID: kungokhala chete komanso yogwira. Ma tag a Passive RFID alibe batire ndipo amalandira mphamvu kuchokera kwa owerenga, pomwe ma tag a RFID ali ndi batire yawoyawo ndipo amatha kutumizira ma siginecha mtunda wautali.

Ubwino waukulu wa RFID umaphatikizira kutsatira zenizeni zenizeni, zolakwika zochepa, komanso chitetezo chabwino. Imawongoleranso magwiridwe antchito komanso imathandizira mabizinesi kudziwa zambiri zazomwe zimagwiritsidwa ntchito ndi katundu.

Tekinoloje ya RFID ikukula, ndipo kugwiritsidwa ntchito kwake kukukulirakulira m'mabizinesi komanso m'moyo watsiku ndi tsiku.
