The Sort-A-Matic system included 100 metal or leather dividers numbered 00 through 99. Each check was placed in the corresponding divider by the first two numbers of the account. The sorting process was then repeated for the next two digits of the account number, and so on. When the process was complete, the checks were grouped by account number.

A metal "key" was inserted through the holes to separate all of the checks with the same value in the first digit, and this step was repeated for each digit until all the checks were sorted.

g. With the advent of the computer and its movement from the laboratory into the business world, a sorting and matching task seemed ideal. Stanford University and Bank of America were the first to successfully use computers to sort and match checks. They developed what is now known as MICR.

At the second edge, the vertical read head detects a drop in magnetism, which results in a -110 signal level at peak 2.

The peaks do require different amplitudes, but ANSI standards allow them to vary from 50% to 200% of the nominal amplitudes (Canadian standards allow them to vary from 80% to 200% of the nominal amplitudes). This is why the placement of the waveform is so important and why the characters are shaped unusually.

Level?
Signal level can vary based on a number of factors. The amount of iron oxide (concentration) that is present in the character will affect the signal level. This is a function not only of the toner itself, but also of how it is laid on the paper and the pile height, which can be controlled by numerous other cartridge components (i.e., "hot" OPCs).
