Anti-lost wallet:
A Bluetooth chip which pairs and communicates with a phone is implanted into a pre-made wallet. If the paired phone and the wallet is disconnected after a certain distance, the paired phone will receive a notification with sound, alerting the user. The wallet is capable of “two-way search” (wallet can seek phone while connected, and vice versa).
Added a external battery holder for changing battery by soldering, gluing the chip internally.

防遺失錢包:
銀包內置藍牙晶片,可與手機連接,在超過特定距離後會在手機上通知並提醒用家,同時亦可雙向尋找電話或銀包。
