MNI 37XX REFERENCE MANUAL 81
Omni 37xx applications can be developed by VeriFone, customers, or third
parties on customer request. One or more applications must be downloaded
to the Omni 37xx terminal before it can be deployed at a customer site and
used to process transactions.
• Files related to file authentication: The logical component of the VeriShield
security architecture in the Omni 37xx terminal is
file authentication . For an
executable to run on an Omni 37xx terminal, it must be authenticated by the
VeriShield file authentication module.
Two special types of files are required for the file authentication process:
digital certificates (*.crt) and signature files (*.p7s). These file types must be
downloaded to the terminal together with the application files to authenticate.
• Terminal configuration settings: Files or records that contain various types
of data can also be downloaded to an Omni 37xx terminal, including
CONFIG.SYS variables, passwords for accessing protected system mode
functions, the current date and time, the modem country code setting, and so
on (refer to Chapter 4).
Full and Partial
Downloads
When preparing to initiate a download procedure, you must choose either a full or
partial download and the COM 1 port, through the system mode menu options

download method you are using, there are some restrictions on if a full or partial
download is permitted.
The various types of full and partial download procedures are listed and described
in Table 19.
