TBScan 3 is without exaggeration a big step forward regarding Trackable recognition. The reason for this is a completely newly developed OCR engine. The OCR engine is responsible for recognizing all letters and numbers inside an image. Doing this with Trackables is a much more complex task than doing it with a scanned document. This is because Trackables and especially coins come in all shapes, fonts, colors, and designs.
The previous OCR engine used by TBScan was already able to reliably recognize most tracking codes. However, there were several situations that caused problems. For example, if two letters touched each other. While you as a human were able to read the code, the program failed.
For TBScan 3 we have developed a completely new OCR engine based on the latest technology. Because this new OCR engine recognizes the code as a whole rather than just individual letters, tracking code recognition is now significantly faster and more accurate. Many codes that previously could not be recognized are now no longer a problem for TBScan. The deep neural network on which the engine is based was trained with over 100'000 images of Trackables. The results of this are impressive: TBScan 3 is more than 5 times more accurate and 4 times faster than TBScan 2.
Previously, whenever you scanned a tracking code, TBScan verified it using the Geocaching API and only after that, the tracking code got displayed as correct (green). Because this process depends on the speed of your internet connection, you sometimes had to wait quite long until the green display appeared.
TBScan 3 improves this by displaying a code in black before verifying it over the Internet. That way you know when you can stop scanning. While TBScan verifies the code, you can already get the next Trackable ready for scanning. This saves you a lot of time waiting. Once the code has been verified, it will be displayed in green as usual.
Of course, updating to TBScan is free as always. Likewise, the Pro Pro-Version remains at the previous price of 2.99 $.
