Rfid-solutions
RUE “Cryptotech” of Goznak is the leading Belarusian manufacturer of labels (tags) and inlays. Production capacity is approximately 50 million labels (tags) and inlays of HF and UHF standards per year. The main focus of research is the development of finished and semi-finished products, such as inlays, adhesive labels, tags and smart cards.
The production cycle includes all stages from development and design of antenna, to assembly and personalization of smart cards. Capacities of RUE “Cryptotech” of Goznak are approximately 50 million smart cards per year.
Produced RUE “Cryptotech” Goznak RFID cards used in fare systems, access monitoring and recording systems and many others.
Main products:
- RFID inlays.
- RFID-tags.
RFID inlays
Sheet inlays are plastic sheets with chips and antennas inside required for the production of contactless cards.
This variant is very useful semi-finished for the manufacturer, as inlay simplifies and speeds up production.
Depending on needs, the supply of inlays in various formats can be chosen:
- PVC Inlays.
- Inlays based on PET with hot adhesive.
- PET Inlays for direct printing.
RFID-card is a plastic or paper (cardboard) card, usually rectangular in shape, which is integrated with the RFID-chip antenna. Such a device is used for non-contact identification of goods, services and people.
Plastic or cardboard cards represent a protective container for the chip and the antenna that allow minimizing the harmful effects of the environment or humans. If the RFID-card is made of cardboard, the chip antenna is glued between two layers of paper that are pre-applied to the desired picture. For greater safety of the chip between the cardboard layers an extra layer with a hole in the place of chip can be put. This layer will let to align the antenna and the chip thickness (since the antenna is substantially thinner than the chip, when gluing the RFID-tags without additional cardboard layer the chip is clearly “palpable” and less protected from external influences). Currently, due to their ease of use and simplicity of reading equipment, RFID-cards are used everywhere: in the subway and overland transport, access control systems, electronic systems, such as skipass passes, as library pass and etc.
RFID-tags
RFID-label (transponder, RFID-tag) — is a device that transmits a radio signal in response to a request for reading equipment. RFID-label consists of two components: the transceiver antenna and microcircuit for data storage, processing the incoming request and forming response signal.
RFID-labels are classified by the operating frequency, the power supply, on the type of used memory, as well as design style.
On a working frequency distinguish radio-frequency tags of ranges of LF (125-134 kHz), HF (13,56 MHz), UHF (860-960 MHz). LF tags are used in veterinary medicine and subdermal chipping of animals and humans. HF-labels are developed and applied in access control, payment systems, are widely used for payment in public transport. Finally, UHF-transponders as having the greatest range of identification, are used in warehouse logistics and production lines.
Regarding the power supply (PS) RFID-tags are divided into passive (without built-in PS), active (with integrated PS) and semi-passive (passive tags with small capacity of PS). Each type has its own advantages and disadvantages. For example, active tags have the highest read range (up to 300 meters), but are more expensive than passive. Passive at low cost and ease of manufacture are read at a distance of 10 cm to several meters (depending on frequency and antenna parameters).
Used memory type affects the working methods with such RFID-label. Distinguish tags with memory that can be:
- only read;
- once to record and then read many times;
- repeatedly write and read information.
Functionality of the systems using in work of a RFID tag is comparable with opportunities of applications for bar codes. But, in comparison with bar codes, RFID tags have some advantages and shortcomings.
