3.General information about @MAXX prime
3.1. @MAXX prime key benefits
The @MAXX prime is an all-in-one device and the flagship of the @MAXX token family.
Designed as a USB-stick the @MAXX prime is portable and can be connected to stationary
PCs as well as Laptops. In addition to the normal smartcard reader the internal RF antenna
converts the normal USB-stick together with a dual interface smartcard to a portable mobile
passive NFC token. The microSD card slot creates an additional possibility to enlarge the
existing embedded storage. The downstream port allows users to connect USB Low Speed
devices having the slim USB connector. The typical application field of the @MAXX prime is the
combination of physical and logical access within one device.

3.5. Hardware features and their principle usage
The @MAXX prime is a multifunctional token device, which can be used within a big application
field. It can be used for one application or for a combination of several applications. In the
following paragraphs the usage recommendations are outlined to ensure best user experience.
1. Contact Smart Card Reader for dual interface Smart Cards with antenna connection on
C4 / C8
2. Internal RF antenna
3. micro SD card reader
4. On board flash memory
5. USB expansion slot (via internal USB hub)

@MAXX schematics:
3.5.1. Contact Smart Card Reader
The contact smart card reader is an 8-pin, ISO7816 compliant contact smart card reader for ID-
000 smartcards. Its contacts C4 and C8 are connected with the internal RF antenna. Thus it is
possible to use beside normal smartcards (microprocessor and memory cards) also dual interface
smartcards with additional contacts on C4 / C8. Memory cards can be accessed using SCM’s
Memory Card DLL.
Note: Memory cards which supports C4 /C8 will not be able to work as these pins are used for the
RF antenna.
Within a Windows® environment the smart card reader can be used with the PC/SC driver or with a
preinstalled USB-CCID driver.
Windows® Vista and future Windows® operation systems have the USB-CCID driver as standard
driver already installed. If Windows® XP is used as operating system, the USB-CCID driver is
available as optional update.

3.5.2. Internal RF antenna
The internal RF antenna is connected with the pins C4 / C8 of the smartcard reader for the
usage of dual interface cards.
When a dual interface card is inserted in the @MAXX and the @MAXX is put in the magnetic
field of any contactless reader, the internal RF antenna couples with the reader and an
induction current appears in the antenna thus providing power to the integrated circuit. The
generated current is proportional to the magnetic flux going through the antenna of @MAXX
reader
The carrier frequency of the magnetic field is used as a fundamental clock signal for the
communication between the reader and the card. It is also used as a fundamental clock input
for the integrated circuit microprocessor to function.
To send data to the user token the reader modulates the amplitude of the field. There are
several amplitude modulation and data encoding rules defined in ISO/IEC 14443. The reader
should should be ISO 14443 compliant reader.
To answer to the reader, the integrated circuit card of the @MAXX modulates its way of loading
(impedance) the field generated by the reader. Here also further details can be found in
ISO/IEC 14443.
The best communication between the @MAXX (with inserted dual interface card) and a
contactless reader can be established if the @MAXX is placed on the contactless reader with
the @MAXX bottom side in direction to the contactless reader. The bottom side of the @MAXX
is the side where the label and the smartcard insertion slot can be found. Depending on the
used contactless reader and the used dual interface card, the @MAXX prime establishes a
read out distance between 2cm – 3cm. A little bit bigger antenna within the @MAXX pime A
results to a bigger read out distance up to 3.5cm.
The communication between the reader and the @MAXX with dual interface card is sensitive to
the presence of material or objects interfering with the magnetic field generated by the reader.
The presence of conductive materials like metal in the vicinity of the reader and the user token
can severally degrade the communication and even make it impossible. The magnetic field of
the reader generates Eddy or Foucault’s currents in the conductive materials; the field is
literally absorbed by that kind of material.
The presence of multiple @MAXXs in the field of contactless readers also interferes with the
communication. When several @MAXXs are in the field of a contactless reader, load of the
field increases which implies that less energy is available for each of them and that the system
is detuned.
The communication between a contactless reader and the @MAXX is sensitive to the geometry
of the system {reader, @MAXX}. Parameters like the geometry and specially the relative size of
the reader and @MAXX antennas directly influence the inductive coupling and therefore the
communication.

@MAXX PRIME R EFERENCE M ANUAL 15
3.5.3. Micro SD-Card Reader
The micro SD-card reader is connected with internal USB-hub over the micro SC-card
controller. Micro SD-cards with up to 8GB storage are supported by the controller. MicroSD
complies to SecureDigital™(SD) card Rev. 2.0 and HC-SD (SDHC) specifications.
Beside the embedded flash memory the SD-Card reader enables the user to enlarge the
storage of the device and is listed as a USB Mass Storage Device. No further driver installation
is needed to run the Micro SD-card reader in a Windows®, Linux and Mac environment.
3.5.4. Embedded Flash
Also the embedded flash memory is connected with the internal USB-hub over the flash
controller. The actual hardware design is able to support embedded flash memory up to 4GB.
Several different partitions can be created on the flash memory:
- CD-Rom partition (with Auto-run function)
- Secure partition (PIN protected)
It is also possible to upload data on the flash and to create different partitions on production
level.
3.5.5. USB extension slot
The USB downstream port is connected directly with the internal hub. Due to the fact that the
internal USB hub is a Bus-Powered USB hub, only low-power devices (up to 100mA) can be
connected to the extension slot.
The @MAXX prime has only a USB extension slot for devices with a slim USB connector. The
@MAXX prime A has a regular USB type A extension slot.

3.6. Applications
3.6.1. General
@MAXX prime is a multifunctional device, designed to interface a personal computer host
supporting PC/SC interface or CCID interface with ISO7816 smartcards in ID-000 format.
Further the device can be used as a passive NFC tag by using a dual interface smartcard. And
the @MAXX can be used as USB Mass Storage device and Micro SD-card reader.
The following graphic shows the case study and the needed infrastructure if the @MAXX is
used as a passive NFC token.
A similar use case is the door opener. In this case the host is not seen. The contactless reader
is installed beside the door.

@MAXX PRIME R EFERENCE M ANUAL 17
@MAXX prime itself handles the communication protocol but not the application related to the
token. The application-specific logic has to be implemented by software developers on the host.

3.6.2. Applications provided by SCM Microsystems
SCM Microsystems does not provide payment or transport applications.
SCM Microsystems provides a few applications for development and evaluation purposes that
can function with @MAXX prime. There are many tools provided; here are two of them:
• The NFC forum tag reader/writer is a standalone application that enables the user to
read and write NFC forum compliant records into NFC forum compatible tags. It is an
easy to use tool to configure rapidly NFC forum tag demonstrations. Note: @MAXX
PRIME supports NFC forum tag type 2 and 4, only.
• Smart card commander version 1.1 provides NFC forum record parsing functionality
of NDEF records in XML format as well as scripting functionality which can be very
useful for developers to develop and debug their applications. This tool can be used
for both the contact and the contactless interfaces of @MAXX PRIME.

The link between @MAXX prime and the host to which it is connected is the USB interface
providing both the power and the communication channel.
@MAXX Prime contains the SCM Mask ROM Controller for the SIM Interface. The Mask ROM
firmware can handle all the ISO7816 contact protocol and the PC/SC communication protocol
with the host.

Software architecture
Applications can interface with the driver directly through the PC/SC interface.
The @MAXX prime driver implements PC/SC v2.0 API towards upper layers and full CCID for
the contact slot.
