Cash register

A register is an object in The Sims 2 and The Sims 3. They allow cashiers and merchants to operate on community lots

The Sims 2: Open For Business
For any Sim to actually make a purchase in a business, a cash register and a Sim standing behind it is needed. Obviously no Sim can use a cash register well without some experience, and that's why a talent badge can be earned. This badge can be earned faster if the Sim in question has a high Logic skill. The speed with which a Sim can complete a transaction increases as the Sim becomes more adept. This is good, as customers do not like to wait for a slow cashier. In fact, some Sims may lose their tempers and leave the shop, causing the business owner to lose the money from that sale, and possibly lose a Customer Loyalty star.

If the community lot is not owned by a sim, the cashier will always be a teen.

The Sims 3: World Adventures
Location Registers in The Sims 3: World Adventures come in four forms:
 * Bookstore Register
 * Nectary Register
 * General Store Register
 * Food Register

Each register spawns its respective merchant sim in vacation worlds.
