Efficient access management

As physical access is integrated into many other parts of the business, the importance of securing identities has also increased. Many people want to be able to use a credential for several different things: access, logg in to computers and copying machines. There are more and more applications that the identity will work with. These are often decentralized organizations - instead of having their own equipment for issuing cards locally, they want them distributed from the manufacturer. Through our ordering portal, Serix Online, the customer can order their ID cards online, which our production then produces and distributes. As a customer, you can follow the entire process from order to delivery. There is also the possibility of reporting card data directly into various access control systems via APIs.

Serix IAM is our platform for managing identities and accesses where you have a simple interface for managing people, credentials, authorizations and asset management. Serix IAM can retrieve personal data from, for example, an HR system or your AD and link them to other systems such as an access control system or printing solutions.

What is RFID?

RFID is short for radio frequency identification and is a collective name for a number of variants of technologies that work in several different standardized frequencies between 3 kHz and 300 GHz. The two most common frequencies are 13.56 MHz (Mifare) and 125 kHz (EM).

A reader can read a digital key (for example, keyfob or card) wirelessly, also called contactless. This means that the digital key is embedded with a transmitter and a receiver that do not have to touch the reader to be able to read the encoded information.

The communication occurs through electromagnetic waves, the most common form being radio waves. The radio waves are grouped into three radio frequency ranges: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF). They differ according to application, maximum reading interval and type of RFID product and reader used.

A digital key can be read up to several meters away and does not have to be within the direct line of sight of the reader to be tracked. Depending on the variant of RFID chip used, different distances are required. Some RFID chips are equipped with their own battery and then send out stronger signals that can be read up to many meters away. Other types of chips are powered by a reader. The former is called active RFID and the later one passive RFID.

The uses of RFID are many and the technology is available in everything from our metro cards, gym cards and access cards to mobile phones and credit cards.

Active RFID

Sometimes you need a chip with a more capacity than the passive chips can offer. The more powerful chip needs a power source that allows the chip to work even when it is outside the reading field. It repeatedly tells you ”Here I am!". If the reader receives messages from the digital key, the system knows that it is within a communicational distance. Their range can extend up to several hundred meters and the batteries can last up to 10 years.

Passive RFID

The passive digital keys have no internal power supply. They get enough power from the reader to be able to send a response. Passive RFID products have the capacity to be read from 11 cm up to 10 meters depending on the standard used and how the environment looks like. Thanks to the fact that the passive RFID products do not have a built-in power source, they can be made very small, and they are therefore very easy to place where the space is limited.
