Neopost has begun beta-testing its revolutionary, Mac-based desktop postal-franking system,Simply Postage.

Some 400 UK-based beta testers are currently putting the product through its paces. Simply Postage is connected to a Mac with either USB or a serial port, and it acts like a franking machine.

It weighs the mail and prints out the stamps, payment is made immediately via the user’s account. It works on any Internet-equipped iMac, or Power Mac G3 or G4.

The device - not yet available in the UK - promises to be a boon to the SoHo market. It costs $9.95 a month (plus postage) in the US, and is available in five translucent colours.
