infrared technology
When you walk the streets of Japan, you may see people standing with their phones so close that they are barely touching each other. These people aren't just being awkward; they're exchanging phone numbers.
Infrared technology, or sekigaisen, is incorporated in all Japanese phones. Cell phone users are able to exchange information by turning on their infrared, and choosing a "send information" function via the infrared sensors. The cell phones are held side-by-side with both sensors facing each other at this point, and users are able to receive the sent information, or profile, which includes the person's name, picture, phone number, and texting address (similar to an e-mail address). You are able to edit this information once it is in your phone so you can alter names or write in how you met that person, etc.
Exchanging information via infrared technology is extremely fast and useful; something I really think we should start using in the United States as well. The downside? No fake numbering!
