11.0 What does it mean when a transaction is approved on "Fallback" or prompts for an authorisation number?
The occasional fallback transaction is normal. This may mean there was a momentary break in communications with the bank. However, if you receive several fallback transactions in succession, please call the HICAPS Help Desk for assistance.
For transactions with large amounts that exceed your floor limits, the terminal will not automatically approve them on fallback. Instead the terminal will display "Trans Fallback Enter Auth.No". For these transactions you must call the patient's financial institution to obtain an authorisation number to key into the terminal.
