Mongol Paiza

Origins
The Mongol Empire had an ingenious and efficient reader mail system for the time, often referred to by scholars as the Yam, which had lavishly furnished and well guarded relay posts known asörtöösetup all over the Mongol Empire. A messenger would typically travel 25 miles (40 km) from one station to the next, either receiving a fresh, rested horse, or relaying the mail to the next rider to ensure the speediest possible delivery. To help sort the officials from the riff-raff, a small tablet called a piaza was issued to messengers and other important people. Anyone with paiza was allowed to stop there for re-mounts and specified rations, while those carrying military identities used the Yam even without a paiza.

Effects
Whoever holds the piaza can present it as a sort of pass or form of ID to get into restricted areas. The person veiwing the paiza will simply see it as whatever form of ID is required, though they may experience some confusion after giving it thought later. In addition, each person may only be fooled by the piaza once before its effects stop.

With the advent of electrical scanners, it was found the paiza can also be safely scanned as a keycard if need-be, though it seems the same restrictions apply

Felix's Notes
"I was lucky to find this one in a museum in Australia. Having overheard a guard talking about some 'magic plate' that stopped working, I decided to look for myself. Finding it and breaking into the case was simple, and I was happy to find the effects were true when the security guard who responded to the break-in waved me off as a curator after seeing the artifact. I discovered its limitations accidently trying to get back into anight club after leaving momentarily to use the rest-room. While this was a dissapointing discovery, I have since successfully used it as an ID, a passport, backstage pass, bank ID, drivers license and a security key card, and it remains one of my most used treasures."
