Handheld electromechanical surgical system

A method of using a surgical device, the method comprising:

• decoupling a first handle assembly from an adapter assembly, the adapter assembly supporting an annular reload having a memory;
• coupling a second handle assembly to the adapter assembly;
• reading the memory of the annular reload to determine whether a shipping cap is detached from the annular reload, the shipping cap being configured to maintain staples within the reload and to prevent inadvertent advancement of a staple driver assembly or a knife assembly of the reload;
• at least one of proximally or distally moving a trocar of the adapter assembly, thereby engaging the shipping cap to detach the shipping cap from the annular reload when the first or second handle assembly is coupled to the adapter assembly and the reload is connected to the adapter assembly;
• encoding to the memory an occurrence of the at least one of the proximal or distal movement of the trocar, the at least one of the proximal or distal movement of the trocar being indicative of the shipping cap being detached from the reload;
• and
• attaching an anvil to the trocar after the shipping cap is detached.
