Www.cryptoshop.com. TCOS – OpenSC. TeleSec (now part of Deutsche Telekom AG), Deutsche Post and DATEV are german companies that sold TCOS 2 based preformatted cards until 2007, i.e NetKey E4 cards, SignTrust 1024bit cards and DATEV-cards. All these cards had a TCOS 2.03 operating system and an almost PKCS#15 compatible file-layout. OpenSC has read-only support for these kind of cards.
Since late 2006 TCOS 3.0 cards are available from TeleSec and a test card plus excellent doku reached the OpenSC team in december 2006. Besides 2048 bit keys TCOS 3.0 has some other new features. In december 2007 the TCOS 2.0 driver was extended such that it supports TCOS 3.0 cards as well. The 2048 bit NetKey card was named NetKey E4 V3. If OpenSC would fully support TCOS, one could erase the preformatted card and initialize the card with a fresh PKCS#15 filesystem.
The good news are: With the help of an emulation layer OpenSC can use cards that are almost PKCS#15 compatible.

Many different pad layouts can be found on a contact Smart card A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card with embedded integrated circuits which can process data.
This implies that it can receive input which is processed — by way of the ICC applications — and delivered as an output. Overview A "smart card" is also characterized as follows: Dimensions are normally credit card size. Benefits Smart cards can be used for identification, authentication, and data storage.[1] Smart card can provide strong authentication for single sign-on or enterprise single sign-on to computers, laptops, data with encryption, enterprise resource planning platforms such as SAP, etc. History Contact smart card Electrical signals description.
