Many people carry not only money and bank cards in their wallets, but also other things, but this can backfire on the wallet's owner. We tell you what things you shouldn't keep in your wallet. Gift cards. If you lose your wallet, you may be able to recover bank cards, but gift cards and certificates cannot be recovered. Don't carry these cards with you unless you intend to use them soon.Checks The powder used to print checks uses bisphenol A. This substance is toxic and causes health problems. It is recommended that you come into contact with checks as infrequently as possible. Spare key A wallet can contain data that can be used to identify the owner's name and address. If you keep a key in your wallet, you may become a victim of robbers if you lose it.Condom The contraceptive should be stored in a cool, dry place and not exposed to friction. In the wallet, the condom is constantly rubbing and causing microcracks on it. Bank card PINs An obvious tip that for some reason is still not followed by everyone. The PIN should not end up in your wallet in any form - including written on a separate sheet of paper or even encrypted with symbols found on the Internet. Passwords Logins and passwords from important sites are best remembered and not stored in a written form. It's especially dangerous to carry such data in your wallet. Attackers can gain access to your social networks, mail, and e-wallet. Stash If you do not plan to spend a large sum of money in the near future, you should not carry it around. It is better to put this money into an account or hide it at home.Documents Thieves don't need documents and when a purse is stolen, it usually ends up in the trash. It takes a lot of time and money to recover your documents. All bank cards If you keep all of your bank cards in your wallet, if you lose it, you will be left with no money at all. Make a habit of carrying one card in your bag or pocket.
