The command/term from the cm> prompt will do.

This is a sample. With card inserted into reader. It tells uo your reader's name, whether a card is present and the serial numbr of the card.

/term

Terminal:PC/SC (ACS ACR38U 0)

Status:Card present, 0B012204

Hi socx,

this isn't correct. Try this again - 2 times for the same card and than for an other card. You will see this 4 bytes are the terminal status with following content:

1. byte = internal counter

4. byte = status

See this example:

- /term pcsc:4

--Opening terminal

> /atr

ATR: T=1, N=0, IFSC=254, BWI=4/CWI=5, Hist="JCOP41V22"

> /term

Terminal:PC/SC (SCM Microsystems Inc. SDI010 Smart Card Reader 0)

Status:Card present, 01012204

Last error: -

> /term

Terminal:PC/SC (SCM Microsystems Inc. SDI010 Smart Card Reader 0)

Status:Slot empty, 02001202

Last error: -

> /term

Terminal:PC/SC (SCM Microsystems Inc. SDI010 Smart Card Reader 0)

Status:Card present, 03002204

Last error: -

> /term

Terminal:PC/SC (SCM Microsystems Inc. SDI010 Smart Card Reader 0)

Status:Slot empty, 04001202

Last error: -

> /atr

Call Get Data command to retrieve the CPLC data.

snd: 80 CA 9F 7F 2D

rcd: 9F 7F 2A 40 70 86 17 40 51 21 79 10 0E 61 31 06

47 67 90 96 66 00 00 00 00 00 00 00 00 00 00 00

00 00 00 00 00 00 00 00 00 00 00 00 00 90 00

Chip Serial Number will be at offset 15, length 4bytes

In this example, Serial Number: 0647 6790

... or use the JCOP JCShell Card Manger command "get-cplc". It's a little bit easier.

cm> get-cplc

I have already googled for this and haven't found a clear answer. Maybe someone here could provide me with one.

The serial number, in a java card, is fabricator dependent or is there some global entity that manages it?

Because i need to use some data from the card (it would be better to use "hardcoded" data instead of managing it on the applet) to diversify a key.

Read out the key derivation tag 'CF'. select CMinit-update/ext-authenticateGET DATA (80/84 00 CF 00)You will get unique data constructed from CM AID and CPLC.
