In the run-up to the test, we defined practical requirements and established the following test criteria:
To be able to evaluate these criteria, we have defined several tests for the barcode scanners. First of all, the scope of delivery and functions are checked. The user-friendliness is assessed during the initial setup.
Depending on the device, the available settings are tested through. When scanning barcodes, the accuracy of the recognition and the speed of scanning are assessed. We test over twenty different barcode types with each device.
In order to exclude errors and to ensure that the device can withstand the stress of everyday use, each test is carried out in several passes.
The test criteria are given percentages according to their importance. The final mark is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on the observation of the current market. In addition to popular brand products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come on the market, our test field will be expanded to include them. The new products undergo the same tests as already tested devices.
