I am looking for a WiFi scanner that could interface with a Ninox database on the server.

I want to be able to use a handheld scanner that can scan a QR code and do the following:

-- find entry(ies) in a Ninox entry with the barcode 

-- once found scan a "delete" action to remove from the database

-- once found decrement a "count" field and if 1 delete the record.

-- all this to be done with WiFi to a back-end database without requiring an IOS or Mac device to be operational at the time.

Request: Any suggestions
