PreScan Modes
The PowerScan handheld can be placed in one of two different modes. In order to use PreScan,
it must be in PreScan MultiLane Mode.
PreScan MultiLane Mode
MultiLane Mode is designed to handle different conditions, such as queuing situations where
customers might change from one queue to another depending on wait times, or where
customers form a single line to feed multiple checkstands. In that case, a roving sales assistant
with a handheld scanner reads item bar codes into memory and bags them. A PreScan control
card containing a bar code unique to that transaction is scanned and handed to the customer.
Alternatively, customer loyalty cards can often be used as PreScan control cards.
When the customer reaches the checkstand, the cashier scans the PreScan control card or
customer loyalty card using the Magellan in-counter scanner, which then interfaces with the
handheld unit to recall all stored bar code data for that customer. In this mode the handheld can
store data from multiple customers, and only the data associated with the specific control card is
transmitted to the POS at the end of the transaction. Scan the following bar code to place the
handheld into PreScan MultiLane Mode.
See "Using PreScan" starting on page 57 for details on how to use the system.
