An influential educational organization contacted Damai to seek an educational content distributing solution. This solution enable them to pre-write contents such as videos, photos, e-books, audio lectures into devices. Then specific end users are able to use phones or pads to access these contents via Wi-Fi connection.
2.High Enough H/W and Wi-Fi Transfer speed
3.High Security (Internal Data can’t be copied, changed or deleted by anyone except organization themselves)
The Damai Solution
- Hardware AES256bit Encryption
- Limited Access from PC
- Wi-Fi 802.11 a/b/g/n/ac
- Storage Capacity: 16GB~256GB

Key Design Challenge
Damai developed a PC super tool with which the organization is able to pre-write educational contentinto the devices at the beginning.
All internal data is read-only mode for end user so they can’t copy, change or delete data inside. The device is also encrypted so that only students recognized by this organization has the accessing privilege.
