6.6.1 About Files

Large blobs of data uploaded to / downloaded from the device are referred to as "files" and share a
common set of commands documented here, and special message type Data File Message. Some file
types can be sent in the File Payload fields in "raw" form (e.g. certificates and images) with metadata
coming from the command request and response. Other file types require the addition of MagTek
metadata included inside the File Payload blob; these are documented in the "File Type" subsections of
section 4 Data Types and Shared TLV Data Objects.
Files Types that may come from the host include:
•
EMV configuration
•
Firmware updates
•
Public Key Infrastructure (PKI) Certificates
•
User interface images and prompts
•
EMV kernels
•
SRED BIN tables
File Types that may come from the device include:
•
Read back of the above file types
•
Signature Capture
•
Logs
•
Certificate Requests
The commands in this section share a common list of 4-byte file types, listed in Table 6.6-1. File types
marked as Secured = Yes must be loaded using Command 0xD811 - Start Send File to Device
(Secured); file types that are marked as Secured = No can be loaded using Command 0xD812 - Start
Send File to Device (Unsecured).
