Just like the Title says this is a cache by the Numbers.
This is a pretty simple cache with something a little"extra".
On Cyber Monday of this week I received an advertisement for a new Travel Bug.
It is called the "Code Travel Bug".
I have been seeing this new code a couple different
places lately and I was immediately intrigued.
I decided to search out some info on this Code and found out they are
called QR Codes, QR for Quick Response.
This is what I have learned about QR Codes,
A QR Code (it stands for "Quick Response") is a mobile phone readable barcode that's been big in Japan forever, broke into Europe a while back, and is now getting traction in USA.
In its simplest sense think "print based hypertext link" - simply encode a URL into the QR Code and then point a mobile phone (or other camera-enabled mobile) at it. If the device has had QR Code decoding software installed on it, it will fire up its browser and go straight to that URL.
But it doesn't stop there - a QR Code can also contain a phone number, an SMS message, V-Card data or just plain alphanumeric text, and the scanning device will respond by opening up the correct application to handle the encoded data appropriately courtesy of the FNC1 Application Identifiers that are embedded in the encoded data.
The technical specifications for a QR Code are set down in the ISO-18004 standard so they are the same all over the world, and the only significant variations from one QR code to another (apart from the data it contains) is the number of modules required to store the data. A Version 1 QR Code is a 21x21 array of data elements with the array increasing in size by 4 modules for each increase in version number. The largest standard QR Code is a Version 40 symbol that 177x177 modules in size and can hold up 4296 characters of alphanumeric data (theoretically) compared to 25 characters for a Version 1 QR Code.
While there is still a lot of scope for improvement, the resolution of average present-day camera-enabled portable devices is such that the size of the data modules (dots) on a QR Code of Version 5 or above (37x37) presents a real risk of incorrect decoding of the symbol by the device. When creating a QR Code intended for use with mobile phones and PDA's it's best to stick to Version 4 or lower, and a QR Code symbol of at least 2cm (0.85inches) across.
To make things a bit more robust, the QR Code also contains its own error correction data, internal orientation calibration and self-alignment markers. In this way it doesn't matter whether the QR code is upside down or wrapped around a curved surface, the message will still get through.
A QR Code looks like this,
Anyone with a smart phone can get a QR Reader in there app store, because the developer is not pursuing his Patent Rights a QR Reader is Free.
You can also get a free QR Code Generator for your PC by doing a Google search.
Here is the extra of this cache,
For you Cachers that love to log Trackables, (Like Myself)
This cache has 3 QR Codes that you can scan to get the Tracking Codes so you can Discover 3 of my Personal Geocoins.
(If you don't have a smart phone and really want to discover these 3 Personal Geocoins, after you log this cache you can send me an e-mail and I will give you the codes.)
This is just a new twist using modern technology playing this fun game they call Geocaching!
