I-nigma

I-nigma is a free app that turns your camera into a QR code reader.  QR codes are becoming more and more popular in real-life.  QR codes have many uses.  Companies use QR codes to get people to visit their websites for information or coupons.  By simply displaying QR codes on store doors or newspapers, companies are able to get customers to their digital advertisements.  We use QR codes in mathematics class to visit particular websites such as Mrs. Loy's website or for review activities.
