Replace a Sponsor Certificate
A sponsor may need to clear the current sponsor certificate from a device so that
a new sponsor can load certificates and applications. To do this, the original
sponsor must order a Clear Smart Card from the VeriFone CA. The Clear Smart
Card is specific to the requesting sponsor. It restores a deployment device to the
development state by:
•
Deleting the current sponsor and signer certificates from the device’s
application partition.
•
Restoring the default certificate to the device’s application partition.

Application Memory Logically Divided Into File Groups
The memory of a V
x
810 is logically divided into two main areas, or partitions:
•
Operating system
•
Applications
The application partition is further divided into sub-partitions. These sub-partitions
are called file groups or GIDs.
NOTE
The process for replacing a signer certificate is the same as replacing a sponsor
certificate.
