Non-invasive cards

Proximity Cards

Proximity card is one of the most interesting developments appeared recently. Proximity cards are increasingly common as access-control means, protection against robberies, logistics automation, etc.

Microscopic processor in contained in the inner assembly of proximity cards, having no contacts on the surface. This peculiar characteristic has a great benefit – such a proximity card is consistent enough to surface contamination. It can be passed through a reader unit, or just bring the card closer to it. The card’s styling reminds of accustomed plastic cards.

Special reader unit is used to receive information from the proximity card. It operates on a principle of radio communication - there is no need to take out the card when paying and to lean it to the device.

This peculiarity invests with high security and reliability. The owners of this type of high-tech card may not be afraid of its data stored inside this small device - proximity card performs encryption of all data and transactions regarding its transferring. Contamination and moisture are by no means dangerous for such a card. This device has unlimited availability period, and specially "advanced models" are equipped with indicators sensitive to light. Besides, not a physical obstruction may influence on data transferring while using this card type.

Proximity card – identifier of tomorrow!

Nowadays, the Proximity memory cards of EM-MARINE and MIFARE have become very popular.

EM-MARINE proximity card is distinguished from the MIFARE card by the fact that it functions in the frequency range 100-150 KHz, accessible only for reading with an operational radius up to 70 cm.

MIFARE proximity cards also differ by unsurpassed rate of data exchange between the card module and reading device - less than 10 ms. A unique chip possesses a large protected memory, while a built-in antenna may transmit information at a distance up to 10 m. These qualities of MIFARE smart-card allows quickly, safely and promptly effect payments or transfer funds.

It is also worth noting that MIFARE cards have the highest level of protection against attacks and forgeries. The card is manufactured in a single copy, entered into a secret protocol, and access to information consists of a number of enciphered codes. The chip memory also has several levels of access, which may be opened by means of special keys. The keys themselves are stored within the card security-protection module, only the customer knows them, what ensured an additional protection against infiltration at all stages (from manufacturer to banking systems).

Finally, MIFARE Standard proximity cards possess a high level of functionality and store size – 1 Kbyte.
