[IxDA Discuss] Best Retail Self-Checkout UI and Why

[pauric]

An issue with the Home Depot devices is inherent distrust in the design.
The system knows the weight of every item.  The thinking is to catch out
thieves who place bar codes from a cheaper item on to a more expensive
product.  So, the process breaks down if;
You arent able to balance that 12 foot plank in to the plastic bag,
You move anything off the checkout scale before payment to make more space,
You have 12 bags of bolts and try to scan one bag 12 times.

List goes on, all because one of the primary requirements was to not trust
the user.

My understanding of why some grocery chains have this dual scan/pos
interface is that the the self scan hardware is 'bolted on' to the existing
POS processes these shops have in place.  Two pieces of hardware, customer
is the system integrator - 'nuff said.
