The transporter platform or transporter pad was a raised area in the transporter room; it was located within the transporter chamber. The platform had transporter pads, where the individual or object that was being transported had to be placed in order to be successfully transported. Some transporter systems supported site-to-site transport and did not require the use of the transporter pad at all.

Personnel transporter platforms often consisted of multiple individual pads sized approximately one per person. Early 23rd century Federation transporter platforms typically had six pads in a hexagonal arrangement; by the latter end of that century they were generally placed in a circular arrangement with a larger pad in the center for bulky items, an arrangement that continued to be used into the 24th century. (Star Trek: The Original Series; Star Trek V: The Final Frontier; Star Trek: The Next Generation) Notable exceptions to this rule include the early transporter models of the 22nd century, which only had one large circular pad. (Star Trek: Enterprise)

Cargo transporters often consisted of one large pad. (TNG: "Datalore", "Symbiosis", "The Hunted", "Power Play")

Each pad in a Federation transporter had four redundant molecular imaging scanners, so that if one of the scanners failed, the other three took over. When necessary, the entire platform could be enclosed within a force field. (TNG: "Realm Of Fear","Rascals[!]")

Cardassian space stations were designed with transporter pads in ops like Deep Space 9. (Star Trek: Deep Space Nine)

In "The Cage", the actual transporter pads were clearly split by three colors, mirrored from front to back: yellow, blue, and green, presumably correlating to the Starfleet uniform division colors of the period. Starting with "Where No Man Has Gone Before", the individual pads all used a white light, which continued for the remainder of TOS.
