Nothing can spoil a vacation quicker than losing your money or credit cards. A few simple steps before you head out of the door can help protect your cash, card and personal information while you’re traveling.

Paul Stephens, a policy analyst San Diego, notes that people spend a lot of time planning their trips, from buying guidebooks to finding just the right beach outfits(装备).“But their eyes glaze(呆滞) over when the subject of keeping money safe comes up,” he said.

“Why not take a few minutes to do something that could probably save your vacation?” Stephens asked.“In most cases, they can go on your to-do list with‘ buy travel bags’ and everything else,” he added.

The top recommendation is to clean your wallet. Remove unnecessary credit cards and any other unneeded documents that could compromise(危及...的安全)your identity if lost or stolen while you’re on vocation.

Then make a photocopy of the cards you’ve decided to take along and keep it in a secure location with you(not in your wallet)or leave it with a trusted relative or friend back home. Then you will know who you need to contact and how to reach it if your wallet is missing.

“Travelers should never leave their wallets or any identifying documents in their hotel room when they’re not there,” he said.” Choose a hotel with a safe to keep your valuable things in. Or keep your wallet and documents with you at all times. ”
