The most common type of RFID tag does not contain a battery (unless it is an active tag). Instead, it receives energy from the radio waves emitted by the RFID reader. When the tag detects the signal from the reader or antenna, that energy powers the tag\u2019s chip. The chip then encodes the desired information into the signal and sends it back to the reader\/antenna.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Differences_Between_RFID_Inlays_RFID_Labels_and_RFID_Cards\"><\/span><strong>Differences Between RFID Inlays, RFID Labels, and RFID Cards<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"981\" height=\"348\" src=\"http:\/\/1gate.monamedia.net\/wp-content\/uploads\/2023\/11\/RFID-tag-1-1.png\" alt=\"\" class=\"wp-image-1258\" srcset=\"https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-1-1.png 981w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-1-1-300x106.png 300w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-1-1-768x272.png 768w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-1-1-400x142.png 400w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-1-1-600x213.png 600w\" sizes=\"(max-width: 981px) 100vw, 981px\" \/><\/figure>\n\n\n\n<p><strong>RFID inlay<\/strong> is the functional core of an RFID label. It consists of the RFID chip and antenna, and it can be used independently by simply attaching it to the target asset. There are two types of inlays: dry inlays and wet inlays. Dry inlays require an additional adhesive layer to attach them to the desired surface, whereas wet inlays already come with adhesive backing.<\/p>\n\n\n\n<p><strong>RFID labels<\/strong> include an RFID inlay embedded on one side with an adhesive layer. These labels can be affixed to assets for the purpose of tracking, identification, and management.<\/p>\n\n\n\n<p><strong>RFID cards<\/strong> encapsulate an RFID inlay within a protective housing. Unlike labels, producing an RFID card requires securing the inlay inside a casing in a way that ensures it remains unobstructed to allow for uninterrupted signal transmission from the RFID reader.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"500\" src=\"http:\/\/1gate.monamedia.net\/wp-content\/uploads\/2023\/11\/RFID-tag-2-1.png\" alt=\"\" class=\"wp-image-1260\" srcset=\"https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-2-1.png 1000w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-2-1-300x150.png 300w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-2-1-768x384.png 768w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-2-1-400x200.png 400w, https:\/\/1gate.com.vn\/wp-content\/uploads\/2023\/11\/RFID-tag-2-1-600x300.png 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p>There are hundreds of types of RFID labels and cards, each designed for specific uses, environments, and asset types.
