The Kaywa Reader is a 2D Barcode Reader to install on your mobile phone. Once installed, you can scan 2D Barcodes and the content of the 2D Barcode is then immediately resolved on the phone. This idea is not new at all, semacodes have been around for a while. What I really liked about this site, though, is their explanation images, demos and user scenarios. Definitely worth checking out. They present the user scenarios clearly. What they don’t really go into is the difficulty in getting the software onto people’s phones (always the difficult part of creating software for mobile phones).
QR Codes (=> Quick Response Codes)
are 2D Barcodes (two dimensional Barcodes) developed by Denso and released in 1994 with the primary aim of being easily interpreted by scanner equipment in manufacturing, logistics and sales applications.
These codes are useful for holding different types of information: a URL, SMS message, phone number, email address or any other text-based data.
And here’s how it works:
(nice nails…)
In comparison with other Barcodes, QR Codes combine several advantages:
- they can hold a very large capacity of numbers or letters in any language
- their printout size can be very small
- they offer high speed reading
- they can be read from any side (omnidirectional or 360° scan)
