certificate

I understand how the relation between issuer and subject certificates enables verification of the subject's authenticity. If I connect to a networked device, and it sends me its certificate to identify itself, then I can verify that it was issued by a trusted party and that it has not been tampered with in any way. However, suppose I simply upload this certificate onto another device. Then what prevents me from having this device identify itself with the copied certificate?
