BellID DataPrep is a software product that belongs to the Token Service Provider platform. Its main role is creating a personalized chip data block that is used for mobile payment applications. It does this according to EMV standards defined by the main payment schemes, using input such as the PAN (which may be tokenized), the cardholder’s name and sometimes a PIN block, along with configuration entities such as an EMV template, a tag dictionary, and a CPS mapping file as input.
During dataprep, cryptographic keys are added to the chip data block so transactions can be processed securely. These keys are managed in the Key Manager instance of Dataprep. The output of DataPrep (a chip data block in TLV format) is usually returned encrypted. In the Perso Bureau configuration entity you must configure which keys are used. In Key Manager you must make sure that these keys are present.
