Cash drawer

Secures the float and the takings, and creates the moment of accountability every time it opens.

A drawer is a lock, a denomination insert and a trigger. The trigger is the part worth understanding before commissioning: the drawer opens on a low-voltage pulse, and on most installations that pulse comes from a port on the receipt printer rather than from the terminal directly. That coupling surprises operators at the worst possible moment — a dead printer is a dead drawer, and the till stops trading for a reason nobody thinks to look for. Underneath there is a manual release, which exists for exactly that failure and is also the hole in the accountability model: any drawer that can be opened without generating a logged event can be opened without leaving a record.

• The decision is not the drawer, it is the accountability model the drawer serves. One drawer, one named operator, one shift, counted in and counted out with a second person present. A drawer three people share through a day is a drawer nobody is responsible for, and it converts every variance into an argument instead of an investigation.
• A card-dominant venue still needs the discipline, and the trap is to under-specify because cash volume is low. Low volume means fewer counts, less practice and weaker habits — the discipline gets worse as cash gets rarer, not better, and the drawer that is opened three times a day is the one nobody reconciles.
• Choose a removable insert if counting has to happen away from the floor, which in most venues it does. Counting on the bar in front of a queue is slow, error-prone and an advertisement.
• Check the opening arc against where people actually stand. A drawer that pushes the cashier back into the barista's hot lane every time it opens is a burn and a collision designed into the counter, and the workflow article's whole argument about crossed paths applies here as much as anywhere.
• Confirm what triggers the drawer and what happens when that trigger fails, in the commissioning meeting rather than during the first rush. If it opens from the printer's port, write the printer failure into the contingency plan explicitly.
• Document who may use the manual release and record every use. An undocumented release is not a security feature, it is an unlogged door.
• Cash is a hand-contact item on a bar that also handles open cups and milk. Site the drawer so the path from handling cash back to handling product passes a sink rather than a jug — this is a layout decision, and it is much cheaper than trying to train around a bad one.
