Next Style with Smartphones

2016/9/13 Quick Pay is more than Credit Pay

Credit Payments have risks with users, companies and banks.
Quick Payments have smaller risks than Credit.

So smartphones instead of wallet is good tactics.

And new lifestyle for people will be that walking only with Smartphone.
Walkers only with smartphones will be one new style.
Free from other baggage is next new style.

I think that next role of Smartphones is ID cards, such like car license cards.

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
