屋台での
オペレーション、
結構大変
しかしながら・・・
• 我が自転車部は部員数25人、オタク20人を抱える厄介サークル
• 当日人が来ない
• 5人しか来ない
• 気づけば数時間後更に人が減っている
• なにげに3万円/日程度の売上がある
• 最小限の設備投資で始めた屋台出店で、設備がフル稼働
• 売上を記録したくても、人を捌くのに必死で忘れる
• 1万円札を出すな
そこで
Squareを導入
なぜ
• 自分が導入したかったから
• インスタ映え間違いなし
• サークル規約等、サークル程度の団
体でも提出できるレベルの各種書類
を提出すれば審査が通る
• キャッシュレス化と売上管理が同時
達成
• レシート発行による待ち番号管理が
可能
サーマルプリンタを購入
kawaii
転がってた泥タブにSquareリーダーと
サーマルプリンタを繋いで実験
ついでに
も導入。
→ 個人ですぐやれるのはECサ
イト向けのサービスばかりだっ
たので、bitWire SHOPの決済URL
のリンクを記載したウェブサイ
トを作り、事前決済してもらう
ことで導入
→ だれでも管理できるように
スプレッドシートで販売品目管
理して、それを元にウェブペー
ジの自動生成するコードをGAS
で実装
効果測定
• カード利用は総売上の13%
• ビットコインで払ったのは1
人だけ
• カード利用者も、1名の親御
さんを除き全て未来大生
• 綺麗に11時から売上が伸び始
め、12時にピークを迎えるこ
とが分かった
業務改善
効果
• 厨房用注文表が出るので、注
文間違いやオーダー提供順の
間違いが減った
• 待ち番号札が出るので、テー
ブルで待ってもらう等ができ
るようになった
• 前日の売上が即時に見れるの
で、翌日の売上予測の確度が
上がり、材料が足りなくな
る・多すぎることが無くなっ
た
副次効果
新たな問題
• 注文主が番号呼んでも来な
• お渡し済か、未調理かが分か
らなくなることがあった
• カード決済の時間が現金より
多少長く掛かる
改善点
• 最近のマクドナルドみたいに、
呼び出し済番号が表示される
仕組みを導入したい
→ SquareAPIのからwebhookで
取引情報から呼出番号と商品情
報を取得できそう(ニヤリ
• せっかくビットコイン用の決
済サイト作ったので、いっそ
の事SquareAPIでスマホ注文で
きるようにしたら面白そう
Square
何か
(リダイレクト
は認めない)
Webhook
レスポンス
POST
まとめ
プログラミングで開発し
てみたいけど、作りたい
物が無い・・・
まずは身近な「不便」の
改善から初めてみよう!
本音
キャッシュレスはいいぞ
次回予告
• Kyashの導入が確定!
• LinePayも個人送金サービスで
行けるか!?
• Origami Payの導入を目論む
が・・・→審査通過
• みんな遊びに来てね!函館に!
