Lifehacker featured this tip from Reddit user lunkavitch who suggested it as a way to stay cool if you lose or misplace your wallet and need some cash to get home or grab a meal. But it's also a great idea for debit-card-only folks who might find themselves in need of paper bill in a crunch. You carry your phone everywhere, so it means you'll always have a bit of cash in a pinch.
Alternatively, you could also invest in a phone case that doubles as a wallet to keep some spare cash around. Check out this post for several phone/wallet options for every style.
We know what you're thinking: What if you lose your phone?! The idea is to keep only small-ish amount — small enough to spare, but large enough to get you out of a pickle. If your $200 phone is lost or stolen, will you miss the extra $20? How about $10? It might be worth risking the small loss to have the peace of mind of knowing you have cash when you need it.
No phone case? No problem. Here are a few more places you can stash away emergency cash in your gear or apartment:
• Inside an old remote.
• Between the pages of an unread book on the bookshelf.
• Inside a zippered pocket of your coat.
• Inside a novelty "safe."
• A hidden storage compartment in a desk, cabinet or table.
• Taped to the bottom of the desk or coffee table.
• In the freezer.
