Counting machines can be classified into portable and electric machines based on size and general functionality. As the name suggests, portable counting machines are typically small and can easily be carried around the workplace. Another typical feature is that they usually have a provision for an internal power source such as a battery, which can be rechargeable or simply replaceable. Portable counting machines are generally designed for those who are looking to have a machine that can fit into a mobile lifestyle or a highly dynamic business environment which involves a lot of moving around. Electric counters are quite the opposite. These are designed for static workstations where there is little to minimal movement. They are typically bulky and cannot be carried around thus they can easily fit in if you are looking to get something to use for high-volume work in a stationary environment.
