RFID bụ otu n'ime teknụzụ njirimara akpaaka (AIDC: njirimara akpaaka na ijide data). Ọ bụghị naanị teknụzụ njirimara ọhụrụ, kamakwa ọ na-enye nkọwa ọhụrụ maka ụzọ nnyefe ozi. NFC (Near Field Communication) sitere na ngwakọta nke RFID na teknụzụ njikọ njikọ. Yabụ kedu njikọ na ọdịiche dị n'etiti RFID, NFC na MSR ọdịnala?

Otu MSR (Magnetic Stripe Reader) bụ ngwaike nke na-agụ ozi etinyere na eriri magnetik dị n'azụ kaadị rọba. Mpempe akwụkwọ nwere ike ịgụnye ozi dị ka ikike ịnweta, nọmba akaụntụ, ma ọ bụ nkọwa ndị ọzọ nwere kaadị. Ndị na-agụ eriri magnetik dakọtara na ọtụtụ mmemme ngwanrọ ID. A na-enwekarị ngwaike ndekọ ego maka ịkwụ ụgwọ na kaadị magnetik na-ejikarị na kaadị ID, kaadị onyinye, kaadị akụ, wdg.

RFID bụ teknụzụ njirimara akpaka na-abụghị kọntaktị. Usoro RFID kachasị mfe nwere akụkụ atọ: Tag, Reader, na Antenna. Otu akụkụ nke nzikọrịta ozi bụ ngwaọrụ agụpụta raara onwe ya nye, akụkụ nke ọzọ bụ mkpado na-agafe agafe ma ọ bụ na-arụ ọrụ. Ụkpụrụ ọrụ ya adịghị mgbagwoju anya - mgbe mkpado batara na oghere magnetik, ọ na-enweta akara ngosi ugboro redio nke onye na-agụ ya zitere, wee zipu ozi ngwaahịa echekwara na mgbawa site na ike nke ugbu a na-ebute, ma ọ bụ na-arụsi ọrụ ike. na-eziga mgbama nke ụfọdụ ugboro, na-agụ na-agụ na decoded ozi. Mgbe nke ahụ gasịrị, a na-eziga ya na sistemụ ozi etiti maka nhazi data dị mkpa.

NFC bụ mbiri nke Near Field Communication, ya bụ, teknụzụ nzikọrịta ozi ikuku dị mkpụmkpụ, na anya nzikọrịta ozi ya dị mkpụmkpụ. NFC na-ejikọta onye na-agụ kaadị na-enweghị kọntaktị, kaadị enweghị kọntaktị na ọrụ ndị ọgbọ na otu mgbawa.
