Secure Access Modules

The security of a contactless system is based on secret keys that authenticate transactions between the terminals and the cards. These keys are stored in the cards, or tickets, and in Secure Application Modules (SAMs). A SAM is a smartcard that is installed permanently in the equipment, interacting with the cards or tickets.

SAMs contain cryptographic keys that are being generated during Paragon ID's key ceremonies and personalised to the terminal function (production, emission, loading or validation etc.). Paragon ID is also the pioneer of SAM issuing in Calypso world, Mifare and other implementations.

Paragon ID provides a comprehensive service for the ticketing systems projects of transport authorities by:

  • Defining the security architecture in accordance with interoperability and specific applications requirements
  • Organising and executing the key generation ceremony
  • Securely storing the master secret keys
  • Ensuring the permanent confidentiality of the keys


Host Card Emulation (HCE) / NFC

Mobile ticketing via NFC allows travellers to substitute their transport tickets, cards and passes with their smartphones. Already used for mobile payment, the NFC technology embedded in most mobile phones can also emulate a transport card allowing passengers to purchase and validate their tickets on their phone. Very easy and convenient to use, it is also extremely secure and gives the best experience to customers. 

Paragon ID has partnered with Wizway Solutions who is the sole industrial player in Europe providing a comprehensive NFC platform, having access to hardware security solutions (such as the Secure Element embedded in Samsung smartphones) and software security solutions such as Paragon ID's HCE (Host Card Emulation) technology.

Host card Emulation is a technology that enables software emulation of a traditional smartcard to enable a mobile device to act as a virtual representation of a contactless smartcard. Paragon ID's NFC / HCE solution is conform to ISO and Calypso standards. Already used by several cities, our solution allow passengers to benefit from an improved user experience.
