What's the difference between a summons card and a summons notice?

The summons card is used to summon illegal suspects in public security cases; If it cannot be summoned, it can be summoned by force (that is, handcuffs can be applied). The summons card can only be issued after it is approved by the director of the police station.

A summons notice is used to summon a criminal suspect in a criminal case. If you are not summoned, you may be detained, arrested and wanted online. The notice of summons shall be approved by the person in charge of the public security organ at or above the county level.

That's roughly what it means.
