Receipts are valuable, and can be used for different crimes. So, you should always ask for a receipt and destroy it at home if you no longer neeed it.  SHOPLISTING - Is when criminals use found receipts to commit crimes. Fraudsters will pick up discarded receipts and then go to the retail store. They will steal the items that are on the receipt, then return to the store with the items and receipt. Then they'll get a refund for the stolen items since they have a legitimate receipt.                                                                                                                                                                                                                                                                                                                                                                                                                                   REWARDS -  Receipts often contain the last four digits of your card number. This isn't enough for a criminal to do much with. But these days many retail stores offer some type of rewards program. These programs often include cash back or other perks if the customer spends a certain amount, and the customer's rewards account is usually included on the receipt. In other words, the receipt could be used to access the customer's rewards account online or in-store. This is commonly done with gas rewards at places such as grocery stores.                                                                                                                                                                                                                                                         Customers earn gas discounts by spending money at grocery stores. But criminals can use the receipt to access the account at the pumps. Essentially, the criminals can get the discount on gas that was earned by the legitimate customer.                                                                                                                                                                                                                                                                                                                     ADDING TO YOUR RECEIPT - All restaurants and even some service-oriented stores will let you add a tip on the receipt. Usually you will receive two receipts. One for you and one for the establishment. Always make sure you take your copy with you.  Also, fill it out so that even if you lose it the amount cannot be changed.  Also, never leave the receipt unattended, and don't leave the restaurant or place of business until the staff had picked up the completed receipt for you.                                                                                                                                                                                                                                                                                                                                                                                             These days, thieves can change the amount of tip or even the total to charge more to your card. They may even run the card twice and get more money. Even if someone added a few dollars to your tip amount it could add up in the long run.  The bottom line is, even though your receipt might not have a lot of information it can still be used to commit theft against you or the company.
