10 things you didn’t know you could do with a smartphone
Your phone can read bar codes.
And QR-codes too. All major stores have free barcode readers that can process the information received. Here are 2 main reasons why it’s cool:
- You can scan barcodes on most of the packages that are a part of the USPS, UPS, and FedEx systems and automatically transfer this information to your gadget.
- You can get more information about a product in apps like RedLaser that can check whether there is a more reasonable price available at other stores.
