What chain of custody means
Chain of custody is the unbroken record of who has held an item, in order, from one hand to the next. The term comes from law and forensics, where an unaccounted gap can undermine a whole case, but the idea applies just as cleanly to a mailroom. Every time a parcel changes hands, that handover should be recorded. Miss one link and the chain is broken.
Why it applies to post and parcels
A delivery rarely goes straight from the door to the recipient. It is received, moved, set down, sometimes handed between staff, and finally collected. Each of those steps is a link. For most post it does not matter who carried it across the building. For a sealed legal bundle, a controlled pharmaceutical or a signed financial instrument, it matters a great deal, and someone will eventually ask.
The sectors that need it
Chain of custody moves from useful to essential in a few settings. Legal practices handling served documents. Pharmaceutical and laboratory sites moving samples. Banks and financial services receiving sensitive instruments. Government buildings with security obligations. In each, the ability to show an unbroken record is not administrative tidiness, it is part of meeting the standard the sector is held to.
What chain of custody software must capture
To hold up, the software has to record every transfer, not just the first and last. That means a timestamp and an identified person at each handover, no step that can be skipped when things are busy, and a record that cannot be quietly edited after the fact. The definition of chain of custody hinges on that continuity, so any tool worth the name enforces it rather than trusting people to remember.
How Traizr keeps the chain intact
Traizr records each scan as its own event, so a parcel that passes through three sets of hands carries three links, each named and timed. Nothing relies on memory, and the trail is there to be read in order. It feeds directly into proof of delivery and the wider compliance record, and it is why sensitive settings such as law firms rely on it.
See it on your own deliveries
If your organisation has to answer for who held an item and when, a spoken account is not enough. A recorded, unbroken chain is. To see how Traizr builds one as a matter of course, book a demo.
