Smart Cards

Smart Card technology allows you to finally "lose the key."

A Brief History

Electronic credential technologies date back to the early 1980’s when swipe technologies were first introduced to the market. These were a major breakthrough and laid the groundwork for access control with increased user and traceability. However, the data integrity was at risk each time the card was manually swiped and transferred unencrypted data to the reader. About a decade later, proximity (prox) cards were introduced. The 125 kHz low-frequency contactless cards were not susceptible to wear and also led to the development of key fobs and tags. Yet, the data was still unencrypted, lending itself to be easily cloned or forged. At the turn of the century, first generation smart cards were introduced to the market. These cards operated at 13.56 MHZ, a much higher frequency than traditional prox cards. The first generation smart cards would mutually authenticate with the reader meaning that each would contain a set of secure communication parameters. Once the card and reader were deemed secure, credentials were shared to determine if the user has the proper access rights for that door. There was another added benefit of smart cards in that the data storage and characteristics of the cards would allow for multi-application use. For example, a college student's card could give them access to their dormitory and manage their meal plan. After industry protocols were established, second generation smart cards were introduced to the market in 2013 and are more secure than previous technologies.

Smart cards have an embedded microchip that can store large amounts of data which lends the cards to be multi-application. Smart cards can be more than a plastic card. They can come in many forms from key fobs to watches with embedded data chips.

While second generation smart cards share a lot of the same benefits, not all smart cards are created equal. The HS4 smart card follows the same design characteristics as the rest of the HS4 system – be robust and dynamic with recognizable quality and physical strength that stands up to daily use and abuse.

One card, multiple systems.

The HS4 smart cards have allocated sectors on the card, meaning there is additional data space to incorporate other systems such as cashless transactions, mass transit passes, etc.

1Kb, 4Kb, and 8 Kb card availability.

The HS4 smart cards are available in 1Kb and 4Kb sizes. Typically, 1 Kb cards are best suited for users with less than 20 transactions per day.

13.56MHz contactless RFID identification

The higher frequency allows for read-write capabilities where lower frequency cards, such as 125KHz are limited to read-only. By using a smart processor, 13.56MHz also provides more security than lower frequency prox cards. This also allows for the reader to power the card when it is within 4 inches of the reader. Through energy transfer between the reader and the integrated circuit, the smart card can send data transfers to the reader as well as receive data transfers from the reader.

Read-write technology.

Typical prox cards are read-only, meaning they are an open door policy where read-write smart cards transactions are password protected (encrypted). As previously explained, the higher frequency (13.56MHz) establishes an energy transfer between the reader and the embedded circuit, allowing for read-write activity.


No more worn magnetic stripes.

ISO 14443 A,B & ISO 15693.

International standard for Contactless Smart Cards operating at 13.56 MHz that defines the size and physical characteristics of the card, the RF power and signal interface, the initialization and anti-collision protocols, and the high-level data transmission protocols.


Is the trademarked name for the global leading contactless read-write products.

Near Field Communication (NFC).

HS4 smart cards are Near Field Communication (NFC) compatible which utilizes the JUSTin mSVN mobile app so that cards can updated on the fly and offsite.


All cards can be wiped clean, reprogrammed, and reused. And they are waterproof.


Cards are available with the Hager powered by Salto logo or can be ordered without graphics so that the cards cab customized to show printed information such as user name and picture.

Construction Cards.

Construction cards are available and provide construction workers with access to different rooms during construction or remodeling phases.
