TeleSec IDKey

Smartcard with TCOS 3.0 and the applications IDLM, Access, Flexitime and OneTimePass

On delivery TeleSec IDKey contains the abovementioned applications which provide various algorithms and tools for identification, authentication and decryption. The card was specially developed for centrally administrated Enterprise PKIs and is equipped with high quality key material that has been generated and coded into the card in Telekom Security Trust Center.

The TeleSec IDKey cards do not contain personal information upon delivery and need to be assigned to specific persons or systems depending on their intended usage. This assignment is part of the rollout process of the Enterprise PKI. The assignment to specific persons or system (personalization) is carried out during the rollout processes of the Enterprise PKI.

Dual Interface Cards

TCOS Smartcards are available as pure contact-based or dual interface smartcards. In Addition to the contact field for contact based communication, dual interface smartcards are equipped with an antenna that is moulded with the card body and that enables touchless operation. This "air interface" conforms with ISO-IEC 14443, thus allowing to enhance the cards functionality with application scenarios such as contactless access control, payment solutions, electronic ticketing or over the air identification.
