Answer:
SLAM has nothing to do with wildly slamming your parcel around (that is done during delivery , but stands for Scan, Label, Apply, Manifest. It is also a final quality check that weighs the parcel and compares the weight with the expected weight of the items and packaging. Again, if there is a discrepancy, the parcel is checked again manually.
Explanation:
During packing, a bar-code attached to the parcel links the parcel with the related information, but this is only machine-readable. During SLAM, a machine scans this code, prints a proper shipping label that humans can also read, and attaches this label to the parcel.
The SLAM machine looks like it is pressing on the parcel. However, it is moving only slightly above the parcel, and the adhesive label is attached using air pressure instead. A fulfillment center may have somewhere around 10 SLAM machines which checks every parcel before it is delivered.
