Cash register

Registers were introduced in The Sims: Hot Date, and were present in all later expansion packs for The Sims. They are also found in The Sims 2 and The Sims 3. They allow Sims to make purchases on community lots. Except for the register from The Sims: Makin' Magic, which is a kiosk with a cashbox, registers must be placed on a surface, usually a counter.

The Sims
Hot Date included two registers, one cheap and one expensive, and each subsequent expansion pack added a new type of register. Any register can be used on any community lot, but each one will spawn an NPC clerk or cashier that generally fits the theme of the community area introduced in the expansion it's from.

The Sims 2
The Sims 2 included a register, and Open for Business added a second, antique-looking register. Without Open for Business, or on unowned community lots with it, the cashier will be one of several teen NPCs set aside as cashiers.

The Sims 2: Open For Business
If a business owner wants his or her customers to actually be able to make purchases, he or she will need a cash register and a Sim to stand behind it. 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.

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 at markets in vacation sub-neighborhoods. These registers can be placed in home neighborhoods like Sunset Valley or Twinbrook, however they will not contain full purchase inventories. For example, the bookstore register will only sell those books sold in the bookstore rabbit hole when it is placed in a main neighborhood, and not the rare exclusive books sold in the respective sub-neighborhoods.
