Myruns specialises in the most advanced RFID identification technology. Know what it is and how it works.

TECHNOLOGY / WHAT IS RFID

What is RFID

RFID, which stands for Radio Frequency Identification, is a technology whose function is the remote identification (up to 15 metres) of persons, objects, and/or animals.

The special feature of RFID technology is that it does not require a visual field and can read up to 1000 IDs per second, allowing the automation of identification and traceability processes, thereby significantly reducing identification times and eliminating human error.

TECHNOLOGY / RFID SYSTEM

RFID System

A reading system consisting of:

1

RFID Tags

It is a flexible, adhesive, wireless device that has a unique electronic code stored on an IC or microchip for its automated, remote identification.

2

Reading system

It is a system consisting of a reading processor (reader) and an antenna or antennas whose function is to emit a radio frequency signal which, when reflected from the label, collects the information (identification code) from the label.

3

Reading solution

Its purpose is to adapt the RFID technology to the medium or application. The reading solution can result in multiple options: Reading arc, reading posts, reading tunnel, integrated to shelves, furniture, or even briefcases.

4

RFID Software

Is a software that allows you to interact and communicate with the RFID technology. Through different connectivity solutions, the RFID Software can be controlled remotely and in real time. In addition to displaying the data, it can also interact with the reading system (change reading frequencies, change reading intensities, etc.).

TECHNOLOGY / HOW DOES IT WORK?

How does it work?

The system components interact as follows:

The reader acts as the locomotive part of the system and the antennas as its eyes. With proper direction and power of the radio frequency emitted by the antennas, the system will be able to capture the readings up to a frontal distance of 15 metres and with a smaller range toward the sides.

The technical reading process is a radio frequency emission emitted by the reader and a process called ‘backscattering’ performed by the RFID tag. Backscattering is a fronton court effect produced by the tag in which the digital ID information is collected, then processed in the reader, and sent to a cloud for viewing. The ecosystem is capable of processing up to 1000 readings per second without requiring a line-of-sight field.

The keys in any case for the optimal operation of an RFID ecosystem are the read antennas and the tag antennas. The best technology and advice are required to select the appropriate RFID components from an RFID ecosystem usage in specific applications.

The ecosystem may experience reading difficulties caused by the following interferences:

  • Metal: Ya que refleja la señal de radiofrecuencia y genera inestabilidad en las prestaciones de la tecnología RFID limitando en ocasiones el rango de lectura.
  • Líquido: Absorbe la señal de radiofrecuencia y limita su rango de lectura.
  • Superposición de etiquetas: En un espacio reducido las etiquetas superpuestas pueden interferir en la señal.

TECHNOLOGY / TYPES OF FREQUENCY

Types of frequencies

Currently, we are working with three RFID frequencies:

LF

(Low Frequency)

Low-frequency RFID

Trabaja a 135kHz y tiene un rango de lectura muy corto (2 cm o 5 cm normalmente). Este tipo de tecnología es útil para aplicaciones como tarjetas de crédito, tarjetas de metro, autobús y sistemas de acceso

HF

(High Frequency)

High-frequency RFID

funciona en 13.56MHz. Tiene un rango de lectura de aproximadamente 12 cm. Este tipo de tecnología es útil para la identificación de objetos en líneas automatizadas donde se puede requerir ausencia de interferencias

UHF*

(Ultra High Frequency)

Ultra-high frequency RFID

Funciona entre las frecuencias 300 MHz y 3GHz (ver normativa UHF Gen2 punto 4). Tiene un rango de lectura de hasta 15 metros. Este tipo de tecnología es útil para trazabilidad de objetos fuera de líneas automatizadas

*En MYRUNS nos centramos en esta frecuencia.

TECHNOLOGY / TYPES OF TAGS

Classes of RFID tags

There are three classes of RFID tags, depending on their ability to interact with the complete system:

PASSIVE

El tag no dispone de batería y responde como un elemento pasivo reflejando la señal de lectura. La etiqueta se compone de una antena de aluminio y un IC. Su rango de lectura puede llegar hasta 15 metros.

tag RFID semipasivo

SEMI-PASSIVE

El tag dispone de una batería conectada al IC. Actúa como un elemento pasivo, pero en el momento de reflejar la señal le inyecta energía para llegar más lejos (30 metros) o transportar información más pesada (ej. Temperatura)

tag RFID activo

ACTIVE

El tag dispone de una batería conectada y actúa como un elemento activo emitiendo constantemente una señal que puede ser leída por el sistema de lectura a un rango de hasta 100 metros.

TECHNOLOGY / TYPES OF READERS

Classes of RFID readers

lector Rfid convencional

CONVENTIONAL FIXED READER

Procesador de lecturas alimentado de 230V y fijado en un cuadro eléctrico con comunicaciones convencional Ethernet.

lector Rfid convencional

FIXED COMMUNICATIONS READER

Procesador de lecturas alimentado de 230V y fijado en un cuadro eléctrico con comunicaciones alternativas: WiFi, LoRa y GPRS.

lector Rfid smartphone

MOBILE READER

Procesador de lecturas con batería e inalámbrica.

TECHNOLOGY / TYPES OF READING ANTENNAS

Classes of RFID antennas

LINEAR POLARISATION ANTENNA

Antena con capacidad para leer tags únicamente en posición horizontal y con alto rango de lectura.

CIRCULAR POLARISATION ANTENNA

Antena con capacidad de lectura de tags en todas sus posiciones.

El método de lectura del código de barras es visual (requiere visión por láser), mientras que el RFID no requiere visibilidad.

Un sistema RFID es capaz de leer el interior de cajas sin necesidad de abrirlas.

The barcode requires individual reads, while the RFID can perform simultaneous reads.

An RFID system can read up to 1000 tags at a time with the resulting saving of time.

Reading the barcode is slow and sometimes a rough surface or dirt on the label can make it even more difficult to read. Instead, RFID is a fast, automatic read.

La etiqueta de código de barras es superficial atendiendo a su método de lectura visual, es difícilmente protegible y puede sufrir daños. En cambio, la etiqueta RFID tiene posibilidad de protección con sustratos plásticos o foam.

Los códigos de barras habituales solamente identifican un producto (como por ejemplo EAN). El Código Electrónico de Producto (EPC) es la información transmitida mediante tecnología RFID. Es un código alfanumérico único, identificando cada ítem unívocamente de otros ítems.

información que aparece impresa en un código de barras es fija y no puede modificarse. Sin embargo la información electrónica codificada en la etiqueta RFID puede ser recodificada y por tanto puede ser reescrita tantas veces sean precisas.

El código de barras es una tecnología visual y fácilmente reproducible. Mientras que la información del RFID es más fácil de ocultar y es encriptable.

TECHNOLOGY /RFID vs BARCODE

Benefits of RFID technology

The implementation and use of RFID technologies arise from the need to optimise the traceability of identification and tracking processes across multiple applications. Some of its advantages are mentioned below:

REDUCED TIME TO REGISTER ENTRIES

RFID technologies reduce the time in entry logging while providing a real-time inventory.

REDUCED TIME IN BILLING AND SALES

All the information is automated and can be read by readers.

ADVANCED CONTROL AND MANAGEMENT OF INFORMATION

With all the information automated, it is easy to access and manage the existing information.

REGISTRATION OF INVENTORY MOVEMENT BY DAY/TIME

All movements that are made (entries and exits) are accurately recorded with date and time.

REDUCED TIME IN PHYSICAL STOCK

Control of automated exits and entrances which reduces the time in making physical inventories.

REDUCTION OF LOSS AND MISPLACEMENT OF GOODS

The RFID technologies seek to prevent loss and misplacements, whether inside a factory or during transport, in a highly rigorous and, above all, controlled environment of security.

REGISTRATION OF SALES BY ITEM, MODEL, SIZE, ETC.

Registration of all existing information about each article and easy access to it.

COST CONTROL AND PREVENTION OF NEEDS

By registering the information, a more rigorous control of costs is possible as well as to forecast the company's stock requirements.
