Xiaomi announced today the Inter-Transfer Alliance group, where it is joined by Oppo and vivo to create an AirDrop-like service for file transfer. The platform is currently in open beta and will allow devices from different manufacturers to exchange photos and documents with a simple swipe or click.
According to the company, the exchange of files wouldn't use a lot of battery nor would it use 4G data or a third-party app – it is based on Bluetooth. Speeds would reach up to 20 MB/s, so a standard 720p movie would be transferred between phones in under two minutes.
Currently, the Inter-Transfer Alliance (the name is just a rough translation) has only three members, but Xiaomi is welcoming others to join. It is a safe bet that brands like Realme and Redmi will also be a part of the team, given their parent companies are on board.
