Bulk capture

The bulk detection is used to automatically detect the objects of the logistics in logistical processes without costly separation .

So-called tags are used for identification , which are read without contact via radio. A suitable protocol enables the tags to be addressed individually and also to be programmed individually. The time required for this increases with the number of tags, but is usually less than a second.

The advantage of efficient recording is bought at the price of the disadvantage that the reading system must know the expected number of objects in advance (in contrast to the barcode ). The reason is that a reader can recognize when a tag is in the radio field, but generally not that a tag is missing. The greater the number of tags in the radio field, the higher the probability that a tag will not be recognized due to interference, shielding effects or unfavorable alignment with the antenna.

Other synonymous terms are: bulk reading, multi-tag reading, multiple recognition
