Approximately 50% of microchips injected will not help get a pet home because they are improperly registered, or not registered at all. Any brand microchip can be registered through Fi, so that all pet owners can have access to free microchip registration for life.
Pet owners can quickly register a non-Fi Nano microchip with an active email and their microchip number at nano.tryfi.com/register. It does not require a Vet/Rescue/Breeder's help.
