iPhone Built-in RFID Posts MQTT

iPhone Built-in RFID Posts MQTT To Any Broker You use the iPhone Built-in RFID Posts MQTT messages using the NFC Read Write app. Place RFID tag near iPhone built-in RFID-NFC reader and the tag CSN value is published to the specified MQTT Broker. When you use tag with NDEF data present, this is also included in the MQTT message. Using your iPhone with NFC Read Write app as your MQTT Publisher, your MQTT broker gets RFID-NFC data message in JSON format.  What Is MQTT And Why Use It Firstly, use

Moving To RFID From Barcodes

Moving to RFID from Barcodes was one of the smartest decisions we ever made. Serialio worked with our IT department for a smooth transition. We added RFID-NFC tags to our currently barcoded assets for a seamless transition. Our mobile inventory solution using RFID works nicely with our in-house business processes.  We save significant time and money. We use Scanfobs® brand keyfob sized mobile NFC readers, and desktop USB UHF RFID readers. The Android tablets connect to the Scanfob brand readers with Cloud-In-Hand® Mobile Grid app. The desktop readers connect with SerialMagic

About Anti-Metal RFID-NFC Tags

Anti-metal RFID tags (aka on-metal RFID tags) are specialized RFID tags that can be read from conductive surfaces, such as metal (something that regular RFID tags can’t do). The Problem Before you understand the problem, you need to understand how RFID tags work — When an RFID reader scans a tag, it sends a radio-frequency electromagnetic field that powers the tag (passive tags) and allows the RFID reader to communicate with the tag.    The problem arises when the RFID tag is fixed to a conductive surface, such a s metal.

What is Near Field Communication (NFC)?

NFC is an acronym for Near Field Communication. NFC is a somewhat recent ‘labeling’ for a subset of RFID (Radio Frequency Identification) for short-range, wireless protocols. While NFC type RFID can apply to low frequency (LF), high frequency (HF), and ultra-high frequency (UHF) types, it’s most commonly associated with HF and used for close-range applications (hence the “near field”). NFC has some features that distinguish it from other forms of RFID, such as the capacity for bidirectional peer-to-peer communication. This article, An Introduction to NFC, is part of a series of articles intending

Common types of NFC tags

Although NFC is a subgroup of RFID technology, there are many varieties of NFC tags/inlays to choose from for different solution needs. This page is a summary guide showing common NFC inlay and tag type options available for many common RFID solutions and application needs. This article is a part of the series of articles intended as a practical guide to NFC serving to address many common considerations when selecting an NFC tag type for your unique application or solution.  Clarification — “NFC tag,” as used in this series of articles,

Applications of NFC

There are many, many applications for NFC technology — from the chip embedded in your credit card to streamlining other technologies, such as Bluetooth pairing. The combination of close-range data transfer, ease of use, and versatility make NFC perfect for environments where data transactions have a requirement for location-specific access (for example, you don’t want your credit card chip to be accessible from more than a few centimeters away). Below are some of the most common uses for NFC (note that this is far from an all-inclusive list). Common Use

Factors That Affect RFID/NFC/UHF Read Range

There are a handful of factors that can affect RFID, NFC, or UHF tag read ranges. If you’re interested in understanding the various aspects that affect RFID read range to improve your RFID application or use case, continue reading! Tag Characteristics (SOAP) SOAP is an acronym for the various factors that affect an RFID tag’s performance; size, orientation, angle, and placement. Not to be confused with Simple Object Access Protocol (SOAP). S Size O Orientation A Angle P Placement Inlay Size — As a rule of thumb, the bigger the tag inlay,

Components of an RFID Tag

Inlay The tag inlay consists of the integrated circuit (IC), an antenna, and a substrate to hold it all together. The inlay, on its own, is a fully functional tag; ready to be packaged into either a smart label or another casing. Integrated Chip (IC) The IC is an electronic circuit or microchip that is manufactured at a semiconductor plant. This microchip contains a memory store and a microprocessor or decision making (logic) unit. The IC is configured either as a passively powered device (powered by inductive coupling generated from

An Introduction to UHF RFID

The latest standardization of the Ultra-High Frequency RFID spectrum is the GS1 UHF Gen2 protocol (ISO/IEC 18000-63), which defines the technical specifications (e.g., physical/logical interactions between devices, anti-collision algorithms, security commands, etc.) for RFID devices operating in the frequency of 860–860 MHz. The ITU designated UHF (Ultra-High Frequency) as the radio frequency range of 300 MHz to 3 GHz, while the IEEE defines UHF as only frequencies between 300 MHz and 1 GHz (the rest of the ITU–defined UHF frequency range overlaps with the IEEE’s frequency allocations for the L band and
