With traditional package delivery, staff members typically spend a lot of time logging and organizing deliveries. These packages end up taking up valuable floor space and could remain there for a long time if a recipient forgets to pick it up or can't retrieve it during regular office hours. If packages are delivered to the recipient's door, there is the risk of the package being stolen or lost. Most residents would undoubtedly prefer a delivery system with tracking and security measures to keep their items visible at all times even if they're away from home. Lastly, it can be difficult to impossible to store perishable items that need to be refrigerated until the recipient can pick them up. But with meal kit and grocery delivery, this need is only going to increase.
Locking options: various types of key locking or padlocking facility are available now. Key locking options include flush locks, cam locks, or locks incorporated into a rotating handle; padlocking facilities may be a simple hasp and staple, or else a padlocking hole may be included in a handle, often called a latchlock. More modern designs include keyless operation, either by coin deposit (which may or may not be returned when use of the locker terminates), or by using electronic keypads to enter passwords for later reopening the locker. Some older lockers used a drop-latch which was incorporated into the door handle, and slid up and down and could be padlocked at the bottom in the "down" position, but these are less used now. Three-point locking is not possible with this type of latch, because it needs to be operated by means of a latch that rotates rather than slides up and down; so this drop-latch is probably a less secure locking option, which may be why it is little used nowadays. Prefect Combination locks are very popular in school lockers used in the UK due to their ease of use and the time and cost saved in the removal of locker keys.
