iCLASS cards and readers offer several unique features that enhance traditional RFID technology. These features include:

  • Mutual authentication: Simply put, the card and the reader each need to ensure that the other has matching keys, so that the reader "knows" that the cardholder is legitimate, and the  card "knows" that the reader is authorized to read its information.
  • If the card and the reader simply transmitted the keys to each other for comparison, anyone with technical skills  and a receiver tuned to the reader's frequency could capture the information, and make his own smart card to obtain access. Mutual authentication is a common practice in key-based encrypted communications.

  • Cryptographic data storage: the card and reader each contain complex cryptographic algorithms, which can scramble the transmitted data so that it is unintelligible. To prevent "hackers" from reverse-engineering the algorithm, the card and reader also have random number generators, and each one factors a random number into the algorithm, so that if you were to read the same card multiple times, the data transmitted would be different every time. Each card contains a unique serial number, which is used to encrypt the key that is stored on the card, making the key unique.
  • iCLASS offers DES and Triple-DES encryption for all data stored within the HID Application Area. The encryption is selected and implemented via an iCLASS Field Programmer (for availability, consult HID). The actual encryption is executed in the reader and the function calls necessary will be added to the SDK when available.
  •  Secure reading and writing of data: All data stored on iCLASS cards is secured by Authentication Keys. The iCLASS cards and readers use 64 bit diversified keys. One key is used to protect each of the card's Application Areas.
  • The iCLASS reader can store up to eight Authentication Keys. Even if more than eight keys are in use at a particular site, a reader will only need to store the keys used for its particular application. New keys can be loaded on-the-fly when necessary.
  •  User definable access keys: The iCLASS Field Programmer (for availability, consult HID) will enable end-users to create custom keys for their site. The programmer will generate keys based on a user entry, sometimes called a seed. The generated keys will be used to program a Master Key Card as well as all the other cards for that site. The Master Key Card is then presented to each of the readers to update its keys for compatibility with the newly programmed cards.

Upgrading existing proximity systems

We know that customers may wish to upgrade existing proximity, barium ferrite, Wiegand, contact smart chip or mag stripe  systems over time. In some cases, customers may use proximity/ mag stripe technology in an existing building and use iCLASS technology in a new building. To help customers economically manage these situations, HID is offering several options:

  • If you have an existing proximity or mag stripe system, you may add iCLASS technology to your existing card by affixing an iCLASS Tag to your existing proximity/ mag stripe card. The card will then function with either a proximity/ mag stripe reader, or an iCLASS reader.
  • HID will also be manufacturing credentials with HID proximity and iCLASS technologies in the same credential. Alternatively, we will offer a credential with Wiegand and iCLASS similar to our ProxCard® Plus card, which offers proximity and Wiegand technologies in the same card. A mag stripe is optional on any of the iCLASS cards.

You should also note that you may choose to replace existing proximity/ mag stripe readers with iCLASS readers. As the iCLASS reader offers a standard Wiegand output, a reader upgrade should be relatively easy.

Read range for the iCLASS

The iCLASS product line offers read ranges of approximately 1" to 4.5" (2.5cm to 11.4cm). As with proximity, read range is a function of the size of the reader, the size/form factor of the credential, and is dependent upon local installation conditions. Larger readers, when used with the standard credential (card), provide the longer read range.

Wiegand Output

The reader's Wiegand output easily interfaces with most existing Wiegand protocol access control panels. The reader also reads standard proximity format data from HID iCLASS cards and output data as encoded. Wiegand data (standard HID proximity formats) can be programmed into the cards by HID or by the customer using an iCLASS card programmer.

Users can custom program the same facility code and bit format currently used on an HID proximity system into an iCLASS credential. The iCLASS reader then passes the information to the user's security panel in the same format as the existing proximity readers, thereby making the transaction identical to the existing access control system.

Multiple Card Technologies

You should also note that you may choose to replace existing proximity readers with iCLASS readers. As the iCLASS reader offers a standard Wiegand output, a reader upgrade should be relatively easy.

HID offers multi-technology credentials that allow you to use a mix of technologies in your facilities. For  example, if you are using a mag stripe currently, you may consider either adding an iCLASS Tag to your existing mag stripe card or purchasing new iCLASS cards with a mag stripe. In either case, you will experience the convenience of using a single credential on more than one type of reader.

HID will offer a number of credential options including:

  • iCLASS Cards, Tags and Keys
  • iCLASS Prox
  • iCLASS Wiegand

You will be able to add mag stripes, barcodes, contact smart chip modules, and other technologies, dependent upon the form factor of the credential and the combination of technologies required.
