SDI011 REFERENCE MANUAL 17

3.5. Contactless communication principles and SDI011 usage recommendations

SDI011 is a dual interface reader capable of reading both contact smart cards and contactless
user tokens. The following paragraph focuses on a few specifics of the contactless
communication to outline usage recommendations in order to ensure best user experience.

SDI011 is a contactless reader1 designed to
communicate with user tokens.

User tokens2 are made of a contactless
integrated circuit card connected to an
antenna

User tokens can take several form factors:

 Credit card sized smart card
 Key fob
 NFC mobile phone etc…

Communication between SDI011 and user
tokens uses magnetic field inductive
coupling.

The magnetic field generated by SDI011 has a carrier frequency of 13.56MHz.

3.5.1. Power supply

When the user token is put in the magnetic field of the reader, its 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
the user token.

3.5.2. Data exchange

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 refer to the standard for further details.

To answer to the reader, the integrated circuit card of the user token modulates its way of
loading (impedance) the field generated by the reader. Here also further details can be found in
ISO/IEC 14443.

1

In the ISO/IEC 14443 standard, the reader is called the proximity coupling device (PCD)

2

In the ISO/IEC 14443 standard, the user token is called proximity integrated chip card (PICC)

SDI011 REFERENCE MANUAL 18



It is recommended for proper communication to avoid putting SDI011 in close
proximity of conductive materials.



It is recommended to present only one user credential at a time in front of
SDI011.



It may happen that SDI011 is not capable of communicating with extremely
large or extremely small antennas.



In order to optimize the coupling between the reader and the user token, it is
recommended to put both antennas as parallel as possible



In order to optimize transaction speed between the reader and the card it is
recommended to place the user token as close as possible to the reader. This
will increase the amount of energy supplied to the user credential which will
then be able to use its microprocessor at higher speeds

3.5.3. Recommendations

The communication between the reader and the user token 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 severely 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 user tokens in the field also interferes with the communication. When
several user tokens are in the field of the reader, load of the field increases which implies that
less energy is available for each of them and that the system is detuned. For this reason, SCM
Microsystems has implemented in its driver only 1 slot by default. This means that in the event
several user tokens are in the field of the SDI011, only one will be active. It is possible using
INF configuration to enable up to 4 slots – i.e. to activate up to 4 user tokens nevertheless
depending on the power consumption of the user tokens communication cannot be guaranteed.

Please note that multiple contactless slots feature is supported but is kept disabled by default.

The SDI011 driver on configuration allows the presence and use of several PICCs (maximum 4) at
the same time. The driver can support multiple logical connections and present each of them as a
slot logical device to the Resource Manager and higher components. Also the simultaneous working
of multiple Contactless cards is not guaranteed and depends on the antenna size and the power
requirements of the card.

The communication between the reader and the user token is sensitive to the geometry of the
system {reader, user token}. Parameters like the geometry and specially the relative size of the
reader and user token antennas directly influence the inductive coupling and therefore the
communication.

SDI011 was primarily designed and optimized to function with user credentials of various
technologies having the size of a credit card.

3.6. Applications

3.6.1. General

SDI011 is a transparent reader designed to interface a personal computer host supporting
PC/SC interface with 13.56MHz user tokens like public transport cards, contactless banking
cards, electronic identification documents – e.g. e-passports, e-ID cards, driving licenses etc.

Those user tokens can have several form factors like credit cards, key fobs, NFC mobile
phones or USB dongles like SCT3511 that SCM Microsystems markets.

SDI011 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 SDI011. 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: SDI011
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 SDI011.

4. SDI011 characteristics

4.1. SDI011 high level architecture

4.1.1. Block diagram

The link between SDI011 and the host to which it is connected is the USB interface providing
both the power and the communication channel.

SDI011 has a device controller which is SCM‘s STCII ASIC. This ASIC has several interfaces
available. In SDI011 implementation 3 peripherals are connected to the device controller:

 LED for reader status indication
 A contact smart card interface
 An RF front-end that handles the RF communication

The ASIC embeds flash memory. The flash is programmed during the manufacturing of SDI011
devices. This flash contains the firmware developed by SCM Microsystems to handle all the
ISO7816 contact protocol, the RF communication protocols and the PC/SC communication
protocol with the host. The flash can be upgraded once the device is deployed in the field,
hence enabling firmware upgrades to add and potentially patch features.

The RF front-end ensures the coding/decoding/framing modulation/demodulation required for
the RF communication. It is controlled by the device controller through registers.

The matching circuitry provides the transmission and receiver paths adaptation for the antenna
to function properly.

SDI011 REFERENCE MANUAL 21

4.1.2. Software architecture

Applications can interface with the driver directly through the PC/SC interface.

The SDI011 driver implements PC/SC v2.0 API towards upper layers and uses SCM firmware
commands encapsulated in CCID-like protocol for the contactless slot and full CCID for the
contact slot.

The SDI011 contactless driver handles all the contactless-related intelligence – i.e. ISO/IEC
14443 and the SDI011 firmware handles the raw transport of data to and from the contactless
cards.
