RFID
treshna supplies RFID tags, rfid cards and rfid readers for the New Zealand market. We stock both short range and long range rfid cards and provide complete rfid solutions.
We have RFID products and software for a variety of industries. We concentrate on solutions mostly on the recreation and manufacturing industry. We provide solutions like access control, ticketing, concessions, point of sale and inventory management.
We have a large variety of products ranging from short range to long range scanners. We also have gates and turnstiles, along with ticketing & printing machines for issuing RFID cards. Solutions can be custom made to meet your individual requirements.
We use a number of different standards such as Mifare (ISO 14443) for short distance use, Vicinity cards (ISO 15693) for medium distance and EPC Gen 2 (ISO 18000) for long distance use.. Each standard has its designed use and there are described in more detail below. We also supply a number of different types of rfid cards and key fobs. There come in a variety of shapes and sizes to suit each companies use. We can supply both small and large quantity of cards and readers.
RFID Standards
Mifare (ISO 14443)
We use what is known as Mifare Ultralight, which is by far the cheapest RFID standard to date. It is commonly used for disposable tickets, however can also be used for short distance reading for access control, identification cards, or any other form of ticketing.
The Ultralight cards allow storage of up to 512 bits of unencrypted data. Encrypted standards of Mifare cards are also available. The cards come in different shapes and sizes ranging from the average credit card sized plastic cards to key fobs. It can also be embedded in stickers and cardboard for inventory tracking.
The readers are small and can be placed on any desktop or wall. The reading range however is limited to 5-7cm, so close contact is an requirement.
This is the standard we use for our software GymMaster for access control and membership cards. It is the easiest and cheapest to implement compared to the other standards, however is limited by its reading range.
Vicinity Cards (ISO 15693)
Vicinity cards are very similar to that of Mifare apart from it has a increased reading distance of 1-1.2 meters. It is used for those who want the want increased flexibility in terms of reading distance and durability of cards and key fobs.
The readers allow reading distances of up to 1.2 meters, its similar to that used for security is stores to prevent people stealing items. The cards or key fobs come in a variety of shapes and sizes as well as ones that are more durable in harsh conditions. There are ones which are water proof or can withstand the hash conditions of a ski field in which people carry tags to get access to lifts.
EPC Gen 2 (ISO 18000)
EPC Gen 2 is the latest standard for long distance reading. It has a reading and writing range of up to 10 meters, under optimum conditions. The readers come with external antennas to increase the reading distance. The cards can either be active, which has its own power supply for extended range, or passive, which the traditional ones which does not have its own power supply. Both cards are encrypted to ensure security standards. The cards, like Mifare, can come in a variety of shapes and sizes, and can also be embedded in stickers and cardboard.
EPC Gen 2 is often used for inventory tracking and non contact access control. Because of its long distance capabilities, items with a RFID tag are able to pass through a "door" with antennas on each side and the reader will be able to identify the RFID tag without contact. The same principle can be used to track people, stock, items of any shape and size every time they pass by a reader.
RFID Equipment
Reader
The reader is the equipment that picks up all the RFID tags. Some readers can process the data onboard however most just passes the RFID information to a cental computer, which will then deal with it. Readers are mainly located on a desk or a wall. There are ones designed for either indoor or outdoor use, which are weather proof. For standards such as EPC Gen 2, hand held RFID readers with wireless capabilities are also available.
Some readers come with the ability to use external antenna's for increased reading or writing range. This is mostly used in EPC Gen 2 standard.
Cards
The cards come in different shapes and sizes depending on its intended use. Traditional credit card size cards are the most common and popular. These cards can be custom printed with any form of pictures of words on them. This can be done by us in the factory or yourself if you have the right printer. There are also different types such as key fobs, coins, stickers, cards, or even water proof ones available.
Printers
RFID printers have 2 functions. One function is to print physically to the card or sticker with pictures, names or barcodes. The other function is to write data onto the RFID card itself. Fortunately all printers will do both of these.
Each standard has its own type of printer and printers come in all shapes and sizes, and of course prices vary according to these functions. It may be useful to be able to print your own identification cards with the person's picture on it or change the information on the card. The other use is to track inventory by printing out a RFID sticker and sticking it onto the box. The printers are easy to operate and work like any traditional printer.
