smart card reader authentication with contact chip and / or contactless chip for physical access and logical access
The smart card readers listed on this page are the best on the market today, used for authentication with contact chip and / or contactless smart card-
They are readers for physical access control and logical access
The customer can easily find the type that suits their needs.
CARD READERS are used to read or write smart cards which are currently of three types:
CONTACT CHIP READER
CONTACT CHIP CARDS READERS are part of SMART CARD READERS.
There are various types from the simplest to the most complex ENCRYPTED.
The use of contact smart cards is the widest, ranging from simple cards for gyms, automatic car washes, swimming pools, SPAs, cards for physical or logical authentication or BANKS.
CONTACTLESS READER (without contact)
They exploit radio frequency as the data exchange between the card and the reader takes place via the two antennas of the card and the reader.
In fact, they are also called RFID (Radio Frequency IDentifier) or contactless cards, as they do not have to be swiped on a magnetic stripe reader
To work you need two devices: a smart card reader (active element) and a smart card (passive element).
The reader connected to the computer generates a magnetic field: when a smart card is brought closer to the reader (on average 5 centimeters) the card uses the antenna to transform the magnetic field into current and thus powers the chip.
At this point the two devices are connected to each other and the data exchange is managed by the software.
HF CONTACTLESS (high frequency 13.56 MHz)
The most recent cards, but not the latest ones, use a frequency of 13.56 MHz, the best known are the NXP MIFARE cards which have become a de facto standard.
They use various sectors, which can be used for different services: for example, a sector for access to the company, a sector for access to the canteen, one for access to the coffee machines, etc.
LF CONTACTLESS (low frequency 125 Khz)
LF CONTACTLESS cards are also called proximity cards, low frequency contactless or 125 Khz cards.
They are also called RFID (Radio Frequency IDentification), as the magnetic signal generated by an active device (reader) is intercepted by a passive device (card or tag).
The use of these cards tends, over time, to decrease in favor of high frequency cards as they have more memory and are more flexible
