送る、預ける、予約する、スマートコインロッカーSPACER。 カギは、スマホで手に入れ、スマホをかざして閉めます。 カギはスマホ上で送受信できる電子キーなので、 このスペースアールを使って“荷物の受け渡し”も可能になります。たとえば、 「渡したいモノがあってお互い近距離にいるけれど、時間がなかなか合わない。かといってこの近距離で高い配送料はかけたくない。梱包作業も面倒だし」 そんな場合は、 「近くの駅のスペースアールに荷物を置いておくから受け取っておいて!」と、専用アプリでメッセージとともに電子キーを送ればOK。 お互いが会わずとも荷物の受け渡しが可能になるので、 ECなどの近接取引などにも使えます。 将来的には、 通勤途中や旅先などで頼んでいた荷物を自ら受け取る、という時代へ。 スペースアールが、物流の概念をも変えていきます。(ビジネスモデル特許出願中)
