Clockwise from bottom left
01. Best for superior strength
The Master Lock 1500e ($51) is crafted from boron carbide, a metal used in tank armour and bulletproof vests, which offers maximum resistance to cutting in a super-sleek package. Plus, its smartphone app records access history and receives tamper alerts.
02. Best for fingerprint access
The only fingerprint-secured lock, Cleverlock ($95) uses advanced biometric technology in addition to the Bluetooth that all smart locks share. The slim swing-shackle design means that it has a low profile for tight spaces, giving it added accessibility.
03. Best for tracking
There are location tracking alerts if your lose your luggage, and an additional layer of pin security, but the neatest – and probably most basic – feature of the Airbolt ($79.95) is its remote trigger alarm – perfect if you’re trying to find it in a busy baggage reclaim hall.
04. Best for shared access
There are times when you need to give someone else access to your lock or luggage, no matter how far apart you are, and Dog and Bone’s Locksmart Travel ($59.95) does exactly that with a neat “virtual key” that allows remote unlocking with the press of a button.
