Bap bins are matter transferral devices that are relatively new creations. This sound they make when "beaming" cargo or creatures is similar to "bap," hence the name. They act instantaneously, but the character knows he has been "bapped". The transferral requires a bin to be at both the departure and arrival point to work. The current maximum range between bins is 5000 km.
RulesEditTechexes who operate these devices for a living must have Matter Transferral Devices skill level 9. A White result on a skill check means that the transferral did not work at all, but the character is safe. It is only on a roll of 98-00 that the item or character being transferred was molecularly scrambled and lost forever.
