For companies
Documents and parcels, on the same account
A signed contract, a payroll file, a part for the workshop. Nobody on your staff has to make the trip, and nobody has to pay for it out of pocket.
Why the code matters
Every delivery carries a code. The person receiving it reads the code out, and without it the delivery is not complete. There is no “left at the gate” and no argument a week later about whether it arrived.
The code is not stored anywhere. It is computed, so there is no code sitting in a database for somebody to read.
What DERSA will not carry
Prescription-only medicine, and anything the law does not allow. Better said here than discovered when a courier declines at your reception desk.
