The latest, deluxe end point of these time and attendance tchotchkes and apps is something like Austin-headquartered HID’s OmniKey platform. Designed for factories, hospitals, universities and offices, this is essentially an all-encompassing RFID log-in and security system for employees, via smart cards, smartphone wallets, and wearables.

how do they prevent spoofing of those rfid keys?

To oversimplify, they use the same type of encryption as you might see on a chip-enabled credit card.

Cloning the card isn't enough, you'd also have to clone a specialized key-signing chip to correctly respond to authentication requests.
