Somehow, a wallet stops being a wallet and begins to talk, in a low-key manner, about a life story. It accumulates old habits, old stuff and stuff that is reserved as emergency over the years. What one would have used during the morning stroll after turning 50 might be based on comfort, the ability to see things clearly, and an easy life that can be reflected in the items one would be carrying in the morning. A thinner, smarter wallet might not only be lighter in the pocket but also in the head. It is not about rules or being abrupt. It is more about paying attention to what remains useful and what may as well be a waste of space. Minor changes may simplify everyday life and prevent the emergence of avoidable stress or inconvenience.
Out-of-date identification card

The old IDs that are not in use anymore may lie in a wallet as a habit. They might create a misunderstanding when accidentally used. This can be achieved by letting go of at least that which is representative of the current and putting the past in some secure place.
Too much cash

Keeping huge sums of money may be a comforting experience, yet one may also be cautious about it being lost or stolen should the wallet be lost. A lot of individuals believe it is sufficient to maintain a small sum, and the rest is locked up elsewhere.
Old receipts

Without any warning, receipts end up piling up. With time, they become stained, wrinkled and crammed up in the wallet. It might be prudent to empty them out on a regular basis unless they are still required for a return or record.
Unused credit or debit cards

The cards that are not used frequently may be stored somewhere without a clear purpose. They may complicate the search for the appropriate card when required. Retaining the most pertinent could be a way of easing daily dealings.
Paper with personal notes

Phone numbers, addresses, or reminders that were written many years ago may not be the truth. Such scraps of paper may increase volume and perplexity. It is usually more convenient to handle updated information in a dedicated notebook or computer.
Gift cards of uncertain value

Old gift cards have a tendency to remain in wallets even beyond the time the balance has been forgotten. They might or might not still be valuable. Going through them periodically and deleting the ones that are not utilized would help eliminate redundant clutter.
Loyalty cards rarely used

Loyalty cards to locations that are no longer frequented fill the wallets of many people. Although they used to count as helpful, they may stuff the wallet. It may be easier to keep the ones that remain relevant so that life every day is easier.
Social security information copies

The existence of sensitive information, even in the form of a copy, may also be dangerous in case of the loss of the wallet. Such documents may be better kept in secure places at home and only retrieved when there is a need to do so.
Old business cards

The sentimental reason is that business cards of old acquaintances tend to hang around. Although memories are important, the cards themselves can no longer be useful. It may be more purposeful to leave some meaningful ones elsewhere.
Obsolete emergency notes

Medical notes or emergency contacts may vary over time. Old information might not be useful in emergency cases. These details may need to be updated and reviewed every now and then.
Spare keys

Slipped wallet keys may be cumbersome and straining. They can also destroy cards through time. Another key holder could be more comfortable.
Worn-out photos

The photos that are carried near tend to bend or fade away. Although they are sentimental, they can be stored somewhere where they are not easily damaged by everyday use.
Old membership cards

Previous memberships have gym, club or association cards, which mostly go unnoticed. In case they are not in operation, they might simply occupy space. It helps to leave them behind and make the wallet lighter.
Coins

Coins irritate and make a bulky wallet. Gradually, they enlarge the matter and become heavier. It might assist to use a small coin pouch or empty them on a regular basis.
Anything kept out of habit

There are a few things that remain just because they have always been there. It can be good to stop and challenge each of them. The wallet that indicates the evolving needs could be more comfortable and purposeful on a daily basis.
