Recently, the prices of smartphones have been steadily rising. More companies are considering purchasing used devices to keep costs down when introducing smartphones for business use. However, there are important considerations when buying used devices. One of these is the "condition of the device" (which indicates the state directly related to the use of the device, such as whether communication is possible or if it is locked), which cannot be determined by the buyer. If not properly understood, this can lead to serious troubles that may result in information leaks. Recently, there has been an increase in cases where devices are purchased through personal sales platforms like Mercari, Yahoo Auctions, and flea market apps, but this poses a very high risk for corporate use, so caution is necessary. This article will provide a detailed explanation of the risks and considerations associated with purchasing used devices. *For more details, please refer to the related links.

The other day, I had the opportunity to actually touch explosion-proof smartphones at an exhibition. What kind of image do you have when you hear "explosion-proof smartphone"? To be honest, I had the impression that it would be a "smartphone designed not to explode," which I thought would likely be large, focused on protection, and lacking in usability and design. However, after seeing, touching, and comparing explosion-proof smartphone cases from multiple manufacturers, my impression changed significantly. In particular, I felt clear differences in design philosophy and usability between overseas and Japanese products, even though they were both explosion-proof smartphone cases. This time, rather than providing a technical explanation about explosion-proof devices, I would like to share my honest impressions based on my experience at the exhibition. *For more detailed content of the column, you can view it through the related links.
