Recently, due to the eve of G20, Hangzhou Public Security Bureau required all hotels to install identification equipment combining people and cards. At present, more than 2,000 hotels have used Searle technology's identification equipment, which can identify different hairstyles, makeup and glasses. Based on the most advanced algorithm in the world (Face++), the unique features of human face are calibrated without worrying about the situation that personal witness can't be compared. It is worth noting that you need to use face recognition equipment to pass the verification within the validity period of your ID card to ensure your smooth stay.
