Don't make it easy for pickpockets. Carry your wallet in an inside pocket, preferably one which can be fastened, not your back pocket . If someone bumps into you in a crowd, immediately see if you still have your wallet or purse.
Cash is a favourite target for thieves, so try to avoid carrying large amounts.
When on holiday abroad, take travellers' cheques ot use credit cards. If your credit card is stolen, tell the card company immediately. Keep the phone number handy. If you delay reporting the loss, it could lead to a crime being committed in your name, as a thief could make fraudulent use of your card. Thieves can use credit cards for over the counter and telephone purchases.
