Usai Technology was founded in January 2017, based in Melbourne VIC, Australia. Our company works with the latest technology and practises the best safety and protection plans. Usai Technology designs Bluetooth apps for smartphones and hardware devices for the purpose of protection and safety in any industry.

Usai Technology focuses on wearable safety and smart technology. Our company made such devices and apps, which have reminders, anti lost features, find quickly functions,etc. The Emkey device helps users find their lost items such as keys, wallets, and others. It also works with a mobile app using Bluetooth 5.0 and it’s available for both android and iOS. Smartphones are already great but our company made them slightly smarter; you can take a selfie without touching your phone and without using a selfie stick. Usai technology designed an app in such a way that it can be connected and paired with other devices that can in turn use its functions.

As Usai Technology, we upgraded our device with even more functions such as an 8 GB data storage unit. You can also always have a 550mAh charging power bank with you which can charge any other device.

Our company believes that safety should be the No.1 priority!

Our company is different from other tech companies because of its safety-first ideology and our care for the community.  In this era, safety is very important – especially for women and kids. As Usai technology, we designed a device named Emkey which can assist with alerting others in case of an emergency. If you find yourself in a dangerous situation, with only one touch you can send an emergency signal to your loved ones and the proper authorities.
