Ultra-high-frequency (UHF) RFID tags: 300 MHz to 3GHz And because almost all smartphones function as NFC readers, NFC tags are popular in promotional labels and posters, and are also a good tool for personalized customer engagement. To learn how brands have leveraged NFC technology, read our articles on NFC applications in wine labels or in the healthcare industry. NFC technology provides secure, one-to-one coupling, making it useful for contactless payment applications such as ApplePay™. With larger memory capabilities and two-way communication capabilities, though, NFC tags are much more useful for storing and communicating large amounts of information - making them an incredibly valuable tool in promotional campaigns. And while other RFID types allow for entire pallets of tags to be read at once, NFC tags must be read one at a time. One key difference is that NFC tags have a much smaller read range, often requiring the reader and tag to be no more than a few centimeters apart.
NFC operates in a very specific subset of the high-frequency range -13.56 MHz- and have very different use cases and implementation considerations from other RFID categories. All NFC tags are HF RFID tags, but not all HF RFID tags are NFC tags.
NFC tags are a subcategory of HF RFID technology. Within the HF RFID category are a common type of smart label: Near field communication (NFC) tags. HF RFID tags have longer read range and higher memory capabilities, making them well-suited to cataloging library media or for use in tracking bracelets for theme parks. High-frequency (HF) RFID tags: 3 to 30 MHz Because of this, they’re often used in applications where an RFID label is affixed to a metal substrate, such as inventorying beer kegs or automobiles.
LF RFID tags have slower read rates and shorter read ranges than UHF or HF, but they’re less susceptible to interference by liquids and metals because they have a longer wavelength. Low-frequency (LF) RFID tags: 30 KHz to 300 KHz This gives RFID tags a clear advantage when it comes to driving visibility and efficiency at the supply chain level (called smart label tracking).īeyond distribution and supply chain benefits, many brands are leveraging RFID tags to engage with their customers at a personal level, allowing consumers to access educational content and / or product-specific landing pages by scanning the label. But because RFID tags use radio wave technology, they don’t require direct line-of-sight in order to be read - meaning entire pallets or truckloads of products can be read as quickly as 700 products per second. Similar to barcodes, RFID tags are commonly used to quickly retrieve product- or pallet-level information. It’s easiest to explain RFID tags (or labels) by comparing them to barcodes. Unique information - such as a GS1 Electronic Product Code™ (EPC)- can be programmed into each individual RFID tag, which are then affixed to products, boxes, pallets or even high-value equipment depending on the application. At its simplest level, an RFID reader sends a signal out to an RFID tag and the tag sends back an information-carrying signal. RFID technology relies on radio waves to send and receive information between a tag and a reader.
