You can put your smart­phone’s cam­era to good use for scan­ning bar­codes and QR codes with the help of third-party apps. QR codes are a mo­saic of black-and-white squares that of­fer an ef­fi­cient link to web­sites and can even store small in­for­ma­tion like text, phone num­bers, email ad­dresses, cal­en­dar events or be used to send SMS mes­sages. Launch­ing the app ac­ti­vates the cam­era that has an on­screen fram­ing guide. Line up the cam­era with the QR code and hold the de­vice steadily un­til the app reads the code. In­ter­est­ingly, there are apps that let you cre­ate your own QR codes. Sim­i­larly, us­ing bar­code scan­ner apps, you can scan bar­codes as well.
