RFID (Radio Frequency Identification) tag card wet inlay yɛ substrate a ɛyɛ tratraa a ɛyɛ mmerɛw a ɛwɔ RFID circuitry a wɔde ahyɛ mu, a antenna ne microchip ka ho. Wɔde saa inlays yi yɛ RFID cards, a ɛtumi sie na ɛde data kɔ wirelessly bere a RFID akenkanfoɔ scan no. Wɔtaa hu wɔ kaad a wɔde hwɛ kwan a wɔfa so kɔ hɔ, kaad a wɔde tua sika a wɔmfa wɔn ho nhyɛ mu, ne smart card ahorow mu.
Akenkan kwan, a wɔsan frɛ no akenkan kwan, yɛ parameter a ɛho hia wɔ RFID mfiridwuma mu. Ɛkyerɛ kwan a ɛkyɛn so a RFID akenkanfoɔ bɛtumi ne RFID tag adi nkitaho yie. Akenkan kwan no na ɛkyerɛ sɛnea RFID kaad no betumi ne akenkanfo no ntam kwan ware bere a wɔda so ara hu na wɔkenkan no pɛpɛɛpɛ. Eyi ho hia ma hwɛ sɛ RFID nhyehyɛe ahorow no yɛ adwuma yiye na ɛyɛ adwuma yiye wɔ dwumadie ahodoɔ mu.
RFID tags yɛ adwuma wɔ frequency ahorow mu: frequency a ɛba fam ( LF ), frequency a ɛkorɔn ( HF ), ne frequency a ɛkorɔn yiye ( UHF ). Frequency no nya akenkan kwan no so nkɛntɛnso kɛse.
