Administration Functions
The terminal has some administration/maintenance functions. These are normally invoked from a dedicated EFT Maintenance button.
EFTLink uses DeviceProxy messages to display input prompts on the POS to manage these functions.
Cayan will provide the merchant credentials that are required to set up the connection with the Cayan host. The information consists of five elements: Name, Key, SiteID, DBA, and TerminalID.
These credentials must be entered through the administration functions. The information is stored in the file cayandynamic.properties. The fields Name and Key are stored in an encrypted form. For each POS system, the Cayan core will create a random encryption key to protect sensitive information. The encryption key itself is stored in the file cayan.secure using an EFTLink specific encryption algorithm.
Cayan has created an Oracle account for testing purposes. To connect to the Cayan host from non-US IP addresses, a 'WhitelistRequest' document containing the static IP of the Genius terminal must be sent to Cayan first. It typically takes 2-3 business days for Cayan security to review and then IT to process.
