S-CARD Command

The S-CARD command can be used to access the Smartcard reader embedded within Zebra Cameo

“SC” or Road Warrior models of mobile printers. Differences in Smart Card operation between the Cameo

“SC” and Road Warrior are explainied in detail below. The smart card library implements the T=1 protocol

for IS07816 compliant cards. This allows users to send ASCII commands to the printer and the printer will

in turn forward this command to the smart card with the appropriate header and checksum information.

The printer then returns the card’s response.

For Cameo “SC” mobile printers, the S-CARD command set is only valid on printers with a printer

application at version 41h or above. The software version can be verified by performing a two-key reset

as described in Section 1 of this manual. The number in the “Software:” listing on the second report

must end in 41h or above (e.g. “Software: HTLK41h”). Cameo “SC” models may be equipped with either

Towitoko MICROCHIP or SCM Microsystems SCR135 Smart Card reader only. For Road Warrior mobile

printers, Smart Card support is included in all versions of the printer application. All Road Warrior printers

are equipped with Phillips TDA8029 Smart Card reader only. Information on which particular Smart Card

reader is used is available via a special S-CARD command described later in this chapter.

Note: For clarity of all communication examples in this chapter, Smart Card reader response codes of ASCII “ACK” (hex 0x06) AND

ASCII “NAK” (hex 0x15) were shown as <ACK> and <NAK>. Actual Smart Card responses will contain hex values of 0x06 (ASCII

ACK) and 0x15 (ASCII NAK).

Format of Smart Card Commands:

{Command } { Operation } { Options }

The ‘Operation’ argument indicates how to access the reader. All options must be separated by a

space unless stated otherwise. The options may appear in any order. The S-CARD command must be

issued using the printer utility session command (!U1...) and terminated by a CRLF pair (0x0D0x0A).

Format of Smart Card Command Response:

Response for a successful command:

Explanation of response:

<ACK> = Successfully sent command to the card and received a response.
