The Hall Pass
Based on the same principle as the classic credit card bypass method the Hall Pass is designed to manipulate the door latch between the frame and door. However, now you won't crack your credit card. Made out of stainless steel the Hall Pass is the exact same size as a standard credit card and will fit into any wallet.
Perfect for internal doors - Schools, Office towers, Hotels, Household.
Word of warning - remember to ditch this sucker before your international flight... TSA loves shiny metal.
