7 apps to find holiday deals

If your wallet is getting fat with receipts as it gets thinner on cash, you might want to try Lemon. Snap a photo of a receipt with your smartphone camera and the app will digitize and store the purchase record. Lemon has expanded to become a full mobile record of your wallet: You can take pictures of your credit cards, loyalty cards and IDs and keep them handy for easy access to the numbers (or in case your wallet is lost). Users secure the images with a PIN.

A basic version of the app is free. For $4.99/month, you can activate the "Lost Wallet" button and Lemon's customer service agents will help you cancel and replace your credit cards. For $9.99, the app will process your receipts with full line-item details.
