It is compulsory to have an individual CPx-type card to log in to the INSi teleservice. Three types of cards are supported: CPS, CPE, CPF. 

CPx cards issued before December 2020 have a contactless chip that prevents from overwriting its code.

The new CPS R3V3 cards that are now in circulation have a Mifare Desfire chip. These cards can stock crypto-secret keys that work with the Mifare Desfire protocol.

All the information about this feature is available in the Manual to deploy contactless CPx cards (available to download below). One must be cautious about the data inserted in the chip’s writing code.

We strongly advise against using this section of the chip to stock access rights. The ANS recommends you to use the ANSSI guidelines on using a "transparent" reader in connected mode. This does not involve a cryptographic protocol during a badge authentication – only the UTL (logic treatment unit) takes part in the cryptographic protocol.

ANSSI advises against setting up a “smart” badge allowing a double authentication breaking from the UTL.

All the recommendations on securing systems for physical access and video projection are available in the document below, "Recommendations on securing systems for physical and video projection access".

This midware allows the interfacing between computer applications, such as the Vivoptim doctors portal and the CPS card.
