QRコードのわくわく感

 QR コードとは、いわゆる二次元バーコードである。最近の携帯電話に QR コードリーダ機能が装備されていて主に紙メディアに印刷されたコードをスキャンするだけで情報を取得することができる。

 なんていう解説が要らないくらい QR コードはすでに身近になっているというのに私がこれにハマったのはここ数日の話だ。スキャン機能がある携帯電話を借りてコードをスキャンしては喜んでいる。マイブームである。

 紙に印刷された意味不明な模様をスキャンして情報を取り出すという行為が楽しくて仕方ない。バーコードバトラーが発売された当時、どんなバーコードでもいいからスキャンしてみたかったみたいに。

 DoCoMo のカタログや新聞広告に載っていたコードを一通りスキャンし終えたら次は自分でコードを作成してみた。

Q作くん - QRコード作成 http://kaz.k2.xrea.com/qrcode/

 このサイトのフォームにテキストを入力し、ボタンを押すだけでコードが作成される。手始めに自分のサイトの URL をインプット。

qrcodeurl

 当たり前だけどスキャンしたらちゃんと URL が表示された。次に自分の携帯電話のメールアドレスや電話番号など、アドレス帳情報をインプットしてみた。DoCoMo なら DoCoMo の、au なら au の形式に従ってアドレス帳情報のコードを作成すれば、携帯電話でスキャンしたときに半自動的にアドレス帳に登録することができるらしい。これは便利。
