Deverbal from pass back.

passback (uncountable)
- The circumvention of an access restriction to a physical site by passing one's access card to another person after having entered.
1988, Security Management, volume 32, numbers 1-6, page 107:Because each card reader is programmed for either entrance or exit, users must pass in and out before being allowed to reenter, thus eliminating passback.
