MAAD Qr is an iPhone application that is designed to read QR codes. As a QR reader, the application automatically reads QR codes, (there is no need to initially take a picture of the code you are interested in), PLUS there is a camera zoom feature to assist in reading the smaller code images.
MAAD Qr supports the following QR data formats:-
1. Business cards (both VCARD & MECARD).
2. Telephone numbers.
3. Plain text.
4. URL / web-links.
5. SMS.
6. Geo positions.
