I personally perfer the laptop approach as it can be loaded with all the working tools of the end user including the client side of the SQL engine. This reduces the chance of data loss as you skip a transfer going from a laptop to the back end rather then scanner to PC to backend. Also the laptop will accept full versions of applications rather then so called optimized versions with some features which may be needed not included.
This way it is then very easy to make a front end app to collect and process the data in the field and then upload pertinent data to the network. If you want to use wireless you have better physical range available with a laptop then a wireless scanner. Otherwise you could just have the laptop connect to the network by hardwire and have the end user activate an upload feature within the app. Connectivity back to the network is also not an issue and the laptop can have other work tools installed. This also minimizes the need for additional training for the end users and also reduces the limit on sourcing replacement and service parts for your data gathering system. This will give you real time if you have wireless connectivity rather then bulk dump time.
Well I am not an expert, but just based on prior experience and working by usage and making the mistakes. I have previously used this approach for order filling with Access where the pick list is filled by a stock person, the serial numbers were scanned in and quantities keyed in for items not serialized. It also kept record of the box sequence number the items were placed in. The box sequence numbers were tied to the bill of lading for the outbound shipments so the customer would be able to find their widget upon arrival by retrieving the correct box out of the shipment. This was also helpful if an item was prepared for shipping and was recalled by the quality control area for any reason.
Same laptops were used for inventory spot checks, cycle counts, FIFO stocking and dock to stock controls for inbound material.
Thank you both RuralGuy & Fifty2One. Data loss would definetely be a major headache. Sounds like the laptop approach might make a lot of sense. I know some of these scanners are what they call portable computers with Windows CE or whatever it is. I think they include versions of Excel and maybe word but I haven't run across Access. Any thoughts?
