• Internet order fulfillment with small number of lines but large number of orders and requiring fast/accurate picking.
• Publications fulfillment with large number of orders of many different line items.  Includes both high and low velocity items.
• Jewelry applications with low items count but large order count.  Accuracy is of paramount importance so scanning of UPC codes is required for expensive items but not for lower cost items.
• Automotive parts applications with special orders and replenishment of stock sold the day before.
• Pharmaceutical applications where large numbers of orders must be filled and prepared for delivery to drug stores overnight.  Picking must be fast and accurate.
• Vending machine replenishment where DEX data is provided from each machine and prekitting of needed products must be performed quickly, accurately and in the route/machine sequence for loading onto delivery trucks.
• Convenience store fast replenishment of items sold, based upon point of sale data. 
• Telecommunications applications where serial numbers on some products must be captured during picking.
• Automotive manufacturing applications where parts must be picked and kitted for each work cell and placed into cart positions in the same sequence as the cars coming down the assembly line.  These applications require both fast and accurate picking for just-in-time delivery to the assembly line.
• Small parts orders with a large number of SKUs with a small number of high velocity items and a large number of low velocity items.
• Retail store replenishment orders based on daily Point of Sale data. 
• Shoe replenishment orders where products are picked directly onto carts and packed with the assistance of light modules under cart locations.
• Drug store returns of expired products.  Returned products must be sorted back into supplier order and placed into containers for delivery to manufacturers.
• High rise case picking of products using a man aboard lift where optimized routing greatly reduces travel and vertical movement time.
• Store distribution picking where common SKUs are picked for a large number of stores and distributed to order bays with a 2-phase picking method.
• Common product picking for a very large number of orders using a dynamic slotting method.
• Apparel picking where large numbers of combinations of style, color and size of similar looking products make accuracy difficult.
• Chargebacks from retailers, due to late or incorrectly picked store orders, are large and difficult to manage.
• Food products where specific lot number must be picked or arbitrary lots may be picked but lot number must be captured during picking.
• Incentive compensation picking applications that supply data to an incentive payroll system so fast/accurate pickers are paid more than slower/less accurate pickers.

Basically, any application that must fill a large number of orders with many different line items and requires fast, accurate picking is a good candidate for FastFetch.  Web orders, replenishment orders and manufacturing kitting orders with sequencing are ideal candidates.
