European based, not in the USA. We receive ACARS load sheets that only contain numerical values, no alphabetic ones. We pilots cross check those values ourselves and the rampagent checks if they conform to his loading instructions and actual loaded weights. We always print three copies, one for our documentation, one for the rampagent which will be kept for a year at the departure station and one which will be kept by the senior cabin crew and handed over to the rampagent at the destination station. A digital copy is send directly to the company and kept there.
Currently we still have to copy ZFW and TOW into our ACARS journey log, but that will be changed very soon. In the long run communication of stuff like that will move out ACARS into the EFB which will be constantly online via SATCOM and GSM and is connected to the aircraft avionic on the other hand. Long run in this case means within three years.
