Lim Li Xue, Cheryl Ho, and Ng Ai Ling, students from the National University of Singapore, might have created a wallet that will solve everyone's woes. 

They created KIN, a wallet that helps you sort notes and coins. Change is always handed back to us with notes and cash combined, and it takes a while for us to separate the notes and coins before keeping them in our wallets. This often leads to a longer queue and coins dropping everywhere. 

As for KIN, you can just put your notes and coins into the same compartment and the wallet will do the sorting for you. Watch:

Amazing, isn't it? The wallet is still a Kickstarter project now and is still opened for support. You can start pledging yours here and get a KIN wallet in return. 

Did we also mention that the wallets are waterproof? The KIN wallet is definitely a must-have!
