The new vDoCare smart visitor registration system (vDoCare EasyReg) provides a self-service registration method. Its main function is to achieve record management of visitors entering the nursing homes through thermal imaging cameras and OCR card readers, thereby improving efficiency and accuracy of visitor registration. The thermal imaging camera can screen out the high body temperature visitors in time, and effectively prevent the spread of the epidemic; the OCR card reader can automatically recognize the information on the ID card and quickly complete visitor registration. Smart visitor registration systems not only improve security; it can also save labor costs and become one of the necessary management tools for nursing homes.
