I understand, and what I am saying is that it is rare to have retail employees that _only_ do checkout. Nearly everyone performs multiple roles. Eliminating checkout will reduce the overall workload, but won't necessarily reduce headcount, or enough headcount to offset the cost of RFID tags.

Why is that relevant?
If 5 employees spend 20% of their combined time on checkout, and you get rid of checkout, you can go down to 4 employees, can't you? Why does the exact distribution matter? You'll still have a healthy variety of tasks to spread among those employees.
