S.C. Code Ann. § 45-2-50: Guest register; requirement; identification; form, duration of record; parent of minor.

The innkeeper of a lodging establishment shall keep for at least five years a guest register showing the name, residence, date of arrival, and departure of hotel guests. Every guest shall register, and the registering guest may be required by the innkeeper to produce a valid driver's license, or other identification satisfactory to the innkeeper, containing a photograph of the guest and setting forth the name and residence of the guest. If the guest is a minor, the innkeeper may also require a parent of the guest to register and to accept in writing liability for the guest room costs, taxes, all charges by the minor, and any damages to the guest room or its furnishings caused by the minor while a guest at the lodging establishment. The guest register may be kept within the meaning of this section when reproduced on any photographic, photostatic, microfilm, microcard, miniature photographic, or other process which actually reproduces the original record.
