Amano MJR7000EZ - the differences:

It automatically updates for daylight savings, the other MJR clocks must be reset every few years.
The cards can be set for groups. As a result, it can do semi-monthly pay cycles, properly calculating overtime for each employee, as the employee is assigned a unique card number for the life of their employment.

One example of a group: 100 time cards, two ranges. 000 - 049 and 050 - 099.
000-049 starts Thursday morning, ends Wednesday night. Thursday - Wednesday.
050-099 starts Wednesday night and ends Tuesday night. Wednesday - Tuesday.
THAT'S what this machine does.
