RFID introduction

Of course, the focus of our RFID technology activities, besides training and laboratory testing (measurements, experiments, device development, etc.), is the development of automated identification systems, but we are striving for the contribution of all three areas to the continuous improvement of our services.

Comparison of RDID and barcodes

When designing an automatic identification system, it is important to know the benefits and limitations of possible solutions when choosing the right device. The two Auto ID methods most commonly encountered in commercial and industrial applications are barcode technology and radio frequency identification.

The following are the main similarities and differences between barcode technology and RFID.

Elements of the barcode based system:

Data carrier: Label, packaging or product with barcode
Data writing: label printer, printing press, labeling device
Reading: barcode reader
Interface elements
Device manager and communication assistant software (device to user system communication, if required)
User systems
Connected systems

Advantages:

Low costs, can be produced by several techniques on a wide variety of surfaces.
An accepted, read-only optical reading technique.
Various symbols to encode numeric and alpha-numeric data as required.

Limitations:

Readability is highly dependent on the quality of the symbol (which varies widely due to the great variety of production techniques) and the reader (optics, technology, decoding software, etc.),
Low capacity for 1D symbols: approx. 15 to 50 characters of data storage capacity, depending on the symbol type. The capacity of 2D symbols can be up to 3-4,000 characters. Complex codes (1D + 2D) represent a transition,
The reader “has to see” the symbol,
One code can be read at a time (there is a special exception),
Can be “written” once, it cannot be modified later.

Radio frequency identification – Elements of the RFID system

Data carrier: RFID tag (antenna and microchip)
Data writing: Standard RFID tag purchased from the manufacturer, pre-written, printed and written with a RFID printer
Reading/Writing: Reading/Writing devices (antenna, reading/writing electronics)
Interface elements
Device manager and communication assistant software (device to user system communication, if required)
User systems
Connected systems

Advantages:

It is more efficient than the optical systems (barcode 1D/2D, character recognition, etc.) because it does not need to “see” the label,
The data carrier is manufactured in specialized factories under controlled conditions on machines, which means that its quality is always in line with standard requirements, not like in the case of barcodes,
More information can be stored, forwarded,
“Readable” from long distances,
It can also be used in areas where barcode solutions are not available,
Durable: works in high and low temperatures, dirty environments, etc.
Less chance of errors,
It is possible to read multiple labels at a time,
Readable/Writable data carrier.

Limitations:

The costs of the data carrier are higher than those of 1D or even 2D barcodes, reader and writer devices are almost similar in price except for the lower category,
Radio waves are not regulated in an uniform manner, so most data carriers can be used globally, but require different versions for reading/writing,
Different materials affect radio waves differently, sometimes causing poor

RFID activity at Vonalkód Rendszerház

As the domestic market leader in the industry, Vonalkód Rendszerház has been at the forefront of discovering and applying new technologies and solutions since its foundation.

This effort is underpinned by our diverse high quality educational and research activities, as evidenced by the RFID laboratory built with EU support in 2006. The focus of our RFID technology activities is the development of automatic identification systems. With the help of over 20 years of system integration experience in the domestic automatic identification market, our company began testing RFID as a “new” solution and later integrated it into its range of services.

The system development tasks carried out by VRH cover the following areas:

Preparation of needs analysis
Choosing the device and device system
Device development and modification according based on the given needs
System development
Integration with existing information system with our hardware and software solutions

RFID laboratory

In many cases, the application of RFID technology requires preliminary tests and measurements. The variety and complexity of the tasks prompted our company to establish the first RFID laboratory in Hungary. The design and equipment of the laboratory was completed in 2006, but it has been continuously expanding in terms of resources, as well as measuring and testing functions. The purpose of the laboratory is to facilitate the development of radio frequency automatic identification solutions and to enable enthusiasts of the technology to learn about its applications.

During system development we perform the following tasks:

Creating economic feasibility analyses.
Provide recommendations to properly label an item (merchandise, collector, pallet, etc.) with a RFID tag:
- for use in open applications,
- for closed, restricted use,
in a similar manner, the examination, approval, and identification of existing marking concepts or objects already marked in some way, as well as mapping out issues,
choosing the best method for automatic identification to solve a particular problem
testing the applicability of automatic identification tools (stamps, labels, hardware and software tools) for a given task,
mapping out and solving system and device integration issues of devices and identification solutions.
conducting field applicability tests with our mobile RFID laboratory for our clients.

System integration into enterprise management systems (SUN, ORACLE, etc.)

Integration of RFID applications with enterprise management systems, with the use of utility software and testing. Currently, we have SUN and Oracle solutions.

Demonstration and testing of the dock gate environment (with forklifts and trolleys)

Testing, developing and demonstrating RFID gates for use in warehouse systems in a variety of applications and merchandise types.

Manual reading, testing and demonstration

Reading the identifiers of stored pallets and boxes with a handheld data collector, developing applications for multi-component systems or as a stand-alone solution.

Testing forklift applications

Development, implementation and testing of the use of general (standard pallet applications) and custom (special containers or applications for storage structures) forklift mounted RFID readers and terminals. Testing data collection from shelves, pallets, and unique collector identifiers.

Conveyor belt applications

Testing of identification solutions for products moving on conveyor belts using special antennas (HF/UHF RFID tunnels, etc.) and their unique placement.

Testing RFID stamps

Examination of stamps operating in the LF/ HF/UHF frequency range and preparation of comparative analyses. The tests may include antennas, chip memories, chip fit types, effects of applications near different materials, etc.

Personalization of RFID stamps

Writing data on RFID tags and printing on suitable stamps.

Testing antennas

Testing the antenna’s range is an important part of various system developments, as measurements form the basis of decisions during device selection.
