We’ve all gone to pay for something and realised we’ve forgotten our wallets. It’s an unfortunate but inevitable part of life, unless you do it every time you go out and “lose” your wallet every time you need to settle a bill. Walli is hoping to put an end to an awkward situation. The smart wallet connects to your Android or Apple phone via Bluetooth, and alerts you if you try to leave without it. It also monitors what pocket you use the most, eg for ID or your bank card, and if it is empty for too long, it will send you an alert about that too. It’s a solution to multiple problems. Or you could buy a Trackr or Chipolo, stick it in your wallet and save yourself almost $100 (€90).
