How to choose an access control reader

The access control reader is undoubtedly the most widespread reading device at the moment, despite the increasing popularity of biometrics. Let’s first examine access control readers.

Types and Characteristics of Access Control Readers

According to their purpose, there are various types of access control readers with different technical specifications. The most common ones are those that read access control cards, chips, and bracelets at 125 kHz frequency. (We will discuss the differences in frequencies in another article. There are numerous controversial issues regarding the security and frequency of operation of access control systems, which we will address.) Another widely used format includes readers operating at 13.56 MHz.

Depending on where we place an access control reader, we must pay attention to their protection against external conditions, temperature ranges, and water resistance. It’s beneficial to inquire about the degree of protection and request certificates that verify the technical specifications of each access control reader. Products from VAiOS’s Franky series are encapsulated, withstand variable climatic conditions, and possess a quality certificate.

According to the purpose of the readers and the access control system, we can choose the distance from which cards or chips presented to the reader can be read. Typically, this ranges from a few centimeters to about 40 cm. There are also long-range readers that can read cards from over 6 meters away, suitable for warehouses, parking lots, and other industrial facilities. In places where recognition of a person or vehicle is required from a greater distance.

Contact and Contactless Readers

In business buildings and enterprises, access control readers are often access control readers installed at entrances and exits. Turnstiles are also combined with access control and working time systems, which is a highly effective way to improve security and order.

Another purpose of the access control reader is at entry and exit points of parking systems and barriers. When selecting a reader for a parking system, it’s essential to consider the conditions under which it will operate – rain, sun, snow, and others.

Readers also come in various shapes and colors. The VAiOS series of embedded console readers is interesting. Since we manufacture the plastic molds for our Franky series, they can be made in any color suitable for the client’s interior design.

According to their purpose, each access control reader can be combined with a keypad. This allows the user to enter a PIN code for access. The advantage is that the user learns the code and it cannot be lost or stolen. The inconvenience is that instead of simply presenting a card or chip for access control, a series of digits must be entered, which is more difficult when carrying luggage. From an installation perspective, keypad systems are challenging. They are difficult to install and service.

Biometric access control systems are gaining increasing popularity. These readers recognize fingerprints, facial features, and even retinal patterns. Their positive aspects include a modern and high-tech appearance. Another convenience is that employees cannot “forget” their access medium.

Disadvantages of Biometric Access Control Readers

Unfortunately, biometric readers have several drawbacks:

  • They do not perform well in external conditions. Most readers give errors at higher and lower temperatures.
  • They require frequent servicing. They are difficult to service, replace parts, etc.
  • They are inconvenient for visits by external individuals. Fingerprints must be taken from each person, temporary access must be granted, which takes time for a delegation of 5-6 people.
  • Our fingers often change – in summer heat, gardening work, etc. This makes checking more difficult, sometimes impossible.
  • Biometrics require more frequent maintenance. If a lady with heavily creamed hands checks after her, the reader may need cleaning to function normally.
  • Finally, but not least, biometric readers are more expensive.

Whatever type of access control and working time system you choose, keep in mind that working with employees and creating habits will be necessary. At first, many people perceive it as “restricting freedom”. Therefore, the company needs a clear plan and policy. We can consult and help you in this process (we have gone through it many times with our clients).

Maintenance of the system is also very important. This can be ensured by us or through your representative. You will need at least one “administrator”. Watch out for our next part of the Access Control and Working Time Systems Guide, where we will cover accessories such as bracelets, chips, or cards for access control.
