Create fake receipts for your digital escape rooms. The receipt can be used to hide a password for your escape room. Simple fill out the form to create a receipt. In your escape room mention that Item # such and such (you decide what that is) holds the key to the door to the next room (giving a hint that the name of the product is the password or key). Another approach is to reference something in your story line whose product code is the password. Anything that leads your participants to find the password. Don’t make it too hard to figure out, but don’t make it too easy either.
Item#: The fake product code for your item.
