1 Scope
This European Telecommunication Standard (ETS) defines the interface between the Universal Personal
Telecommunication (UPT) card and the Card Accepting Device (CAD) for the operational phase. It also
defines those aspects of the internal organization of the UPT card which are related to the operational
phase. This is to ensure interoperability between a UPT card and a CAD independently to the respective
manufacturers and UPT service provider.
This ETS only defines the interface between a UPT card and a card reading Dual Tone Multiple
Frequency (DTMF) device (ETS 300 380 [1]).
NOTE: Other types of CADs are under study.
This ETS defines:
- the requirements for the physical characteristics of the UPT card, the electrical signals and the
transmission protocol;
- the model which shall be used as a basis for the design of the logical structure of the UPT card;
- the security features;
- the interface functions;
- the commands for operating the interface functions;
- the contents of the files required for the UPT application;
- the service set to be supported in the UPT card;
- the application protocol (security, services, etc.);
- the Implementation Conformance Statement (ICS) proformas.
This ETS does not specify any aspects related to the administrative management phase. Any internal
technical realization of either the UPT card or the CAD are only specified where these reflect over the
interface. This ETS does not specify any of the security algorithms which may be used.

4 Physical characteristics
Two physical types of UPT card are specified. These are the "ID-1 card" (see ISO 7810 [6]) and the
"plug-in card" (see ENV 1375-1 [16]).
The physical characteristics of both types of UPT card shall be in accordance with ISO/IEC 7816-1 [9] and
ISO/IEC 7816-2 [10] unless otherwise specified. The following additional requirements shall be applied to
ensure proper operation in the UPT environment.
4.1 Format and layout
The identification number as defined in EF (see clause 10) shall be present on the outside of the ID-1
ID
card. The information on the outside of the plug-in card shall include at least the individual account
identifier and the check digit of the IC card identification.
4.1.1 ID-1 size
Format and layout of the ID-1 card shall be in accordance with ISO/IEC 7816-1 [9] and
ISO/IEC 7816-2 [10].
The card should have a polarization mark which indicates how the user should insert the card into the
CAD .
UPT
The CAD shall accept embossed ID-1 cards. The embossing shall be in accordance with
UPT
ISO 7811-1 [7] and ISO 7811-3 [8]. The contacts of the ID-1 card shall be located on the front (embossed
face, see ISO 7810 [6]) of the card.
4.1.2 Plug-in size
The plug-in card has a width of 25 mm, a height of 15 mm, a thickness the same as an ID-1 card and a
feature for orientation. See annex A for details of the dimensions of the card and the dimensions and
location of the contacts.
Clauses A.1 and A.2 of ISO/IEC 7816-1 [9] do not apply to the plug-in UPT card.
Annex A of ISO/IEC 7816-2 [10] applies with the location of the reference points adapted to the smaller
size. The three reference points P1, P2 and P3 measure 7,5 mm, 3,3 mm and 20,8 mm, respectively,
from 0 with the values in table A.1 of ISO/IEC 7816-2 [10] replaced by the corresponding values of
figure A.1.
4.2 Temperature range for card operation
The temperature range for full operational use shall be between -25°C and +70°C with occasional peaks
of up to +85°C. "Occasional" means not more than 4 hours each time and not more than 100 times during
the life time of the card.
4.3 Contacts
The provision of contacts shall be in accordance with ISO/IEC 7816-2 [10].
4.3.1 Provision of contacts
CAD : There need not be any contacting elements in positions C4 and C8.
UPT
Contact C6 need not be provided.
UPT card: Contacts C4 and C8 need not be provided by the UPT card.
Contact C6 shall not be bonded in the UPT card.
4.3.2 Activation and deactivation
The CAD shall connect, activate and deactivate the UPT card in accordance with the operating
UPT
procedures specified in ISO/IEC 7816-3 [11].

Page 14
ETS 300 477: September 1996
For any voltage level, monitored during the activation sequence, or during the deactivation sequence, the
order of the contact activation/deactivation shall be respected.
NOTE1: It is recommended that whenever possible the deactivation sequence defined in
ISO/IEC 7816-3 should be followed by the CAD on all occasions when the CAD
UPT UPT
is powered down.
NOTE2: The voltage level of Vcc used by UPT differs from that specified in ISO/IEC 7816-3.
Vcc is powered when it has a value between 4,5 V and 5,5 V.
4.3.3 Contact pressure
The contact pressure shall be large enough to ensure reliable and continuous contact (e.g. to overcome
oxidization and to prevent interruption caused by vibration). The radius of any curvature of the contacting
elements shall be greater than or equal to 0,8 mm over the contact area.
Under no circumstances may a contact force be greater than 0,5 N per contact.
4.4 Precedence
For a CADUPT which accepts both an ID-1 PIM and a plug-in PIM, the ID-1 PIM shall take precedence over
the plug-in PIM.
5 Electronic signals and transmission protocols
Electronic signals and transmission protocols shall be in accordance with ISO/IEC 7816-3 [11] unless
otherwise specified. The following additional requirements shall be applied to ensure proper operation in
the UPT environment.
The choice of the transmission protocol(s), to be used to communicate between the PIM and the CAD ,
UPT
shall at least include that specified and denoted by T = 0 in ISO/IEC 7816-3 [11].
The values given in the tables hereafter are derived from ISO/IEC 7816-3 [11], subclause 4.2 with the
following considerations:
-V and V always refer to the device (CAD or PIM) which is driving the interface. V and V
OH OL UPT IH IL
always refer to the device (CAD or PIM) which is operating as a receiver on the interface;
UPT
- this convention is different to the one used in ISO/IEC 7816-3 [11], which specifically defines an ICC
for which its current conventions apply. The following clauses define the specific core requirements
for the PIM, which provide also the basis for Type Approval. For each state (V , V , V and V )
OH IH IL OL
a positive current is defined as flowing out of the entity (CAD or PIM) in that state.
UPT
- the high current options of ISO/IEC 7816-3 [11] for V and V are not specified for the PIM as
IH OH
they apply to NMOS technology requirements. No realisation of the PIM using NMOS is foreseen.
5.1 Supply voltage
The PIM shall be operated within the following limits:
Table 1: Electrical characteristics of VCC under normal operating conditions
Symbol Minimum Maximum Unit
Vcc 4,5 5,5 V
Icc 10 mA
The current consumption of the PIM shall not exceed the value given in table 1 at any frequency and
voltage accepted by the PIM.
When the PIM is in idle state (see below) the current consumption of the card shall not exceed 200 μA at
1 MHz and 25°C.
Page 15
ETS 300 477: September 1996
The CAD shall support the current as required above. It shall also be able to counteract spikes in the
UPT
current consumption of the card up to a maximum charge of 40 nAs with no more than 400 ns duration
and a maximum amplitude of 200 mA, ensuring that the supply voltage stays in the specified range.
NOTE: A possible solution would be to place a capacitor (e.g. 100 nF, ceramic) as close as
possible to the contacting elements.
5.2 Reset (RST) (contact C2)
The CAD shall operate the PIM within the following limits shown in table 2.
UPT
Table 2: Electrical characteristics of RST under normal operating conditions
Symbol Conditions Minimum Maximum
V I = +20μA Vcc-0,7 Vcc (note)
OH OHmax
V I = -200 μA 0V (note) 0,6V
OL OLmax
t t C = C = 30pF 400μs
R F out in
NOTE: To allow for overshoot the voltage on RST shall remain
between -0,3V and Vcc+0,3V during dynamic operation.
5.3 Programming voltage
The CAD need not provide contact C6. If the CAD provides contact C6, then contact C6 shall not
UPT UPT
be connected.
5.4 Clock (CLK)
The PIM shall operate with a clock frequency between 1 MHz and 5 MHz. The clock shall be supplied by
the CAD . No "internal clock" PIMs shall be used.
UPT
The duty cycle shall be between 40% and 60% of the period during stable operation.
The CAD shall operate the PIM within the following limits:

NOTE: To allow for overshoot the voltage on CLK shall remain between -0,3V
and Vcc+0,3V during dynamic operation.
5.5 I/O (contact C7)
Table 4 defines the electrical characteristics of the I/O (contact C7). The values given in the table have the
effect of defining the values of the pull-up resistor in the CAD and the impedances of the drivers and
UPT
receivers in the CAD and PIM.

NOTE 1: It is assumed that a pull-up resistor is used in the interface
device(recommended value: 20kohms).
NOTE 2: During static conditions (idle state) only the positive value can apply. Under
dynamic operating conditions (transmission) short term voltage spikes on
the I/O line may cause a current reversal.
NOTE 3: To allow for overshoot the voltage on I/O shall remain between -0,3V and
Vcc+0,3V during dynamic operation.
5.6 States
There are two states for the PIM while the power supply is on:
- the PIM is in operating state when it executes a command. This state also includes transmission
from and to the CAD ;
UPT
- the PIM is in idle state at any other time. It shall retain all pertinent data during this state.
The PIM may support a clockstop mode. The clock shall only be switched off subject to the conditions
specified in the SELECT response to the MF.
Clockstop mode: A CAD shall wait at least five (5) elementary time units (etu's) after having received
UPT
the last bit of the response before it switches off the clock (if it is allowed to do so). It shall wait at least two
(2) etu's before it sends the first command after having started the clock.
5.7 Baud rate
(clock frequency)
The baud rate for all communications shall be: .
5.8 ATR
The ATR is information presented by the PIM to the CAD at the beginning of the card session and
UPT
gives operational requirements.
5.8.1 Structure and contents
Table 5 gives an explanation of the characters specified in ISO/IEC 7816-3 [11] and the requirements for
their use in UPT. The ATR consists of at most 33 characters. The CAD shall be able to receive
UPT
interface characters for transmission protocols other than T = 0, historical characters and a check byte,
even if only T = 0 is used by the CAD .
