WE DID IT! The GUINNESS WORLD RECORD for the largest display of key cards consists of 20,000 key cards, achieved by Accor X Fliggy X GCS Times in Chengdu, Sichuan, China on 25 October 2024.

The entire challenge was live-streamed, aiming to assemble 20,000 wooden key cards (made by @GCS Times) into a massive poster, featuring nine iconic tourist sites worldwide.*Note: The key cards on display had to be standard key cards available on the market, either now or in the past, and each one needed to be unique, with no repeated colours, patterns, or text. After several hours of effort, a large-scale key card mosaic was unveiled to everyone. After verification, the Guinness adjudicator announced that the final result confirmed that 20,000 key cards broke the previous record!

Each wooden key card used instead of a PVC card reduces carbon emissions by 61 grams. Congratulations to everyone who received a key card from this challenge—you were part of a Guinness World Record and supported eco travel at the same time!
