Cash Drawers: when looking for a cash drawer it’s very important to evaluate the construction of the drawer. You can choose thin metal, heavy metal or plastic – heavy metal construction will obviously last longer and make it more difficult to break into. Look for things like solid slide wheels and track, quality release mechanisms, and solid construction.
Another consideration when purchasing a cash drawer is the size of the cash drawer and where it will be placed. You need to decide whether you want the cash drawer on the counter or underneath. If the drawer is under the counter, you need to drills holes for the drawer wiring. Then you’ll need to measure your counter space or the opening underneath. If you decide to place the cash drawer on your counter, it should be large enough to place the printer, keyboard and monitor on top of it.
There are 2 main types of interfaces for cash drawers. The most popular interface is the RJ interface, which connects the cash drawer to the receipt printer: the port on the receipt printer sends an electrical signal to the cash drawer that pops the drawer open. The 2nd interface is a direct connect to the computer using a serial or USB port on the back of a computer to open the drawer
Other things to consider when selecting a cash drawer are media slots and locks. Media slots are used for slipping checks and credit card receipts in the drawer without exposing the cash.
