A police report for a lost or stolen travel document gives the day it was stolen and the day it was reported. Software can take either as the day the document was issued.
Biographic sheets list other names in columns of first, middle and last name. Software can read the columns in the wrong order or run rows together.
The form splits weight into one box per digit and height into feet and inches. Software can put the whole number in the first box.
A receipt number, an A-Number, an online account number, an I-94 number and an old document number can all sit in one file. Software can put one in another’s box, or keep the letter and dashes.
Payroll records and intakes often show only the last four digits. Software can copy the masked number into the form.
