When the Galaxy S21 series was released in January this year, Samsung stated that the mobile phone will have a digital key and smart home function. After about 8 months, the digital key function was finally officially launched yesterday. Samsung announced that it will add a digital key function to the Galaxy S21+ and S21 Ultra through the October Android security update. Car owners can add the digital car key to the Samsung Pass of the mobile phone. The car manufacturers that support Samsung Pass include BMW, Audi, Genesis and Ford. The owners of the corresponding car models only need to bring an updated Galaxy S21+ or S21 Ultra mobile phone. In the wireless charging board in the car, the car owner can even start the engine directly. Samsung said that the digital key function uses the mobile phone’s UWB or NFC technology. The two Galaxy S21 phones are just the first shot, and will be released to the Galaxy Note 20 Ultra, Galaxy Z Fold2 and Z Fold3 later. At this stage, only users in the Korean market can use it, and it will be launched in the US and European markets in the future. Source: Samsung unwire.hk Mewe page: https://mewe.com/p/unwirehk
