Barcode/13 is a full software barcode scanner for Treo 600, Treo 650, Treo 700p, Zire 71 and Zire 72. Barcode/13 uses the camera to scan EAN-8, UPC-A, ISBN and EAN-13 barcodes and exports decoded values to the system clipboard: values can be retrieve from the clipboard within any application. Barcode/13 can be easily integrated in third party applications to automate the scanning process.

Barcode/13 is a free alternative to expensive hardware solutions. Barcode/13 can't be seen as a business solution, but it is definitely the cheapest solution for non-business use, like cave, books, CDs or DVDs inventories.

In preview mode, use the 5-way navigator left and right keys. Left key will leave Barcode/13 with the clipoard emptied, right key will scan the barcode in your target.

In decoder mode, use the 5-way navigator left and right keys. Left key will return to the preview mode to scan again a barcode, right key will leave Barcode/13 with your decoded barcode value in your system clipboard.

Barcode/13 recognizes EAN-13 and UPC-A subset of EAN-13 with a leading 0, but if you have some difficulties with a barcode you can tell Barcode/13 the first digit:

• If your barcode is a UPC-A barcode (US barcodes, 12 digits, x xxxxx xxxxx x) you can start the scanner pressing the "0" key (or Graffiti)
• If your EAN-13 barcode (european barcodes, 13 digits, x xxxxxx xxxxxx) begins with a 3, you can press the "3" key (or Graffiti), and so on.

I recommend using this feature only if automatic recognition fails: usually, I press the digit keys only if Barcode/13 fails twice to read a barcode (this happens more frequently when scanning bottles, you should not need this for standard barcodes in normal lighting conditions). On Treo 650: space key can zoom/unzoom, but you should use this only with very small barcodes.

Barcode/13 is compatible with Treo 600, Treo 650, Treo 700p, Zire 71 and Zire 72. However, some limitations may apply depending on your device: Treo 600's camera produces very saturated pictures and it can be difficult to get a sharp image, Zire 71's camera gives good results but preview mode is pretty slow, Zire 72's camera is very sensitive and an additional calibration has been added in preview mode.

Nominal size of a UPC/EAN symbol is 1.469" wide x 1.02" high, the minimum recommended size is 80% of the nominal size or 1.175" wide x .816" high, the maximum recommended size is 200% of the nominal size or 2.938" wide x 2.04" high. Larger barcodes scan better, smaller barcodes do not scan as well or not at all.

During preview mode you can see two red targets and a green line. Green line is the position that will be used to analyse the barcode, targets are recommended sizes for large and small barcodes. Recent barcodes are often large barcodes, but some products have smaller barcodes.

• If you have a large barcode, point your device to fill the large target with your barcode (keep the barcode inside, don't oversize it).
• If you have a small barcode, the small target will be a better idea.
• If your barcode is medium size, something between the 2 targets will be fine.

Barcode/13 will give you best results if you follow some recommendations:

• Your barcode should be lighted without any shade, the easiest way and recommended way is to face the light source.
• Best distance is about 15cm with barcode parallel to your Treo.
• Barcode/13 works best with surfaces like CDs or DVDs, it is possible to use it with bottles but it may require a little training to get the good lighting conditions and to have a symmetric position.
• Don't move your Treo while scanning the barcode: a fuzzy image won't help!

If you don't have a proper contrast in preview mode, for example when scanning a black colored item, you can place a sheet of blank paper close to your barcode: this will force the camera to adjust the contrast level.
