WiWU Fingerprint Lock Bags Review: Is Biometric Bag Security Worth It?

WiWU's fingerprint lock range puts the same biometric technology you use to unlock your phone onto the zip of your bag. The WiWU Fingerprint Lock Travel Backpack (£129.99) is the flagship, backed by a crossbody bag (£79.99), a laptop bag (£89.99) and a tech storage pouch (£69.99). If you carry valuable tech through crowded places and want keyless, tamper-resistant access, they're among the most interesting bags in our range.

Here's how the technology works, what each bag offers, and where the limits are.

Why Fingerprint Locks Are Showing Up on Bags

Smart features are one of the fastest-growing trends in the backpack market. Buyers increasingly expect USB charging, smart compartments and better security as standard and hybrid working has put more laptops in more bags on more crowded trains. Traditional anti-theft features such as hidden pockets and lockable zips help, but they all rely on you remembering a key or a combination.

A fingerprint lock removes that friction. There's no code to forget, no key to lose and no padlock to fumble with while you're holding a coffee. You touch the sensor, and the bag opens.

How a Fingerprint Lock Bag Works

The principle is the same one used in your phone, scaled down:

1. The sensor. A small capacitive sensor on the bag reads the ridges and valleys of your fingertip.
2. The template. The lock converts that pattern into a digital template and stores it on the lock's own chip. It doesn't need an app, a phone connection or an internet signal to work.
3. The match. When you touch the sensor, the lock compares your print with the stored templates. If it matches, a small electronic latch releases.
4. The zip. On WiWU's bags, the lock is linked to a dual zipper track, so the zips stay locked together until the sensor releases them.
5. The power. Locks like this are typically powered by a small built-in rechargeable battery, topped up over USB. The crossbody bag's specification notes that its lock has no user-replaceable batteries, which points the same way.

One important caution: our product pages don't currently state how many fingerprints the lock can store, how long a charge lasts, or what happens if the battery runs flat. Some other retailers list WiWU fingerprint locks as including a USB charging cable and an emergency key, but these details vary between listings, so check what's in the box before relying on them.

The Range at a Glance

WiWU Fingerprint Lock Travel Backpack: Best for Daily Commuting and Travel

£129.99 | View product

This is the headline product and the best showcase for the technology. The fingerprint scanner is built into the zipper track, so the main compartment opens with your print instead of a padlock or combination dial. The tough PVC shell sheds heavy rain and spills, and a padded laptop bay protects devices up to 15.6 inches, from a 13-inch MacBook Air up to a 16-inch MacBook Pro.

Inside, accessory pockets keep chargers, cables, passports and notebooks organised, and thickly padded, adjustable shoulder straps help on long commutes. The solid black profile suits both offices and weekend trips.

Best for: professionals, students and frequent flyers carrying valuable tech through busy places. If you're comparing it with other secure options, our business backpacks and laptop backpacks collections have more to explore.

Watch out for: at 1.5kg it's heavier than most commuter bags, which is the trade-off for the PVC build and lock hardware.

WiWU Fingerprint Lock Crossbody Bag: Best for Pickpocket-Prone Places

£79.99 | View product

A crossbody or chest bag sits in front of you, which already makes it harder to target, and the fingerprint lock adds a second layer. It's sized for tablets and e-readers up to 10.2 inches, with a padded bay plus pockets for your phone, power bank and keys. The adjustable strap lets you wear it across your chest, on your back or over one shoulder.

Best for: city breaks, festivals, busy commutes and anyone who wants quick access to a phone and passport without opening a backpack. Browse more cross body bags if you want to compare styles.

Watch out for: the compact 29.5 x 18.5 x 10.5cm size suits essentials, not a laptop.

WiWU Fingerprint Lock Laptop Bag: Best for the Boardroom

£89.99 | View product

For anyone who prefers a briefcase to a backpack, this structured PU leather laptop bag brings biometric security to a classic form. A padded compartment protects laptops up to 15.6 inches, and up to a 16.2-inch MacBook Pro. It has top handles and a detachable shoulder strap, and the rigid frame keeps its shape when packed. At 1.19kg and 39 x 29 x 9cm, it's slim and lighter than the backpack.

Best for: meetings, client visits and office commutes where you want a polished look. Our laptop bags collection has more briefcase-style options.

Availability: this model was sold out when we wrote this review, so check the product page for restock details.

WiWU Fingerprint Lock Tech Storage Pouch: Best for Cables and Gadgets

£69.99 | View product

This compact genuine cowhide pouch is a small vault for the things people often forget to protect: power banks, chargers, flash drives, USB cables and USB adapters. Segmented elastic bands and gadget slots keep everything organised, and the detachable wrist strap means it can be carried as a clutch. At 24 x 14 x 6cm, it also slips neatly into a larger bag or suitcase as a locked layer inside.

Best for: travellers and professionals who want a secure home for accessories. It pairs well with a power bank and a set of USB cables. More options are in our tech storage bags.

Availability: this model was also sold out at the time of writing, so check the product page for current stock.

Honest Limitations

• It's a deterrent, not a safe. A fingerprint lock stops casual, opportunistic access, such as a hand slipping into an open zip on a crowded train. Like any soft bag, it can't stop someone determined with a blade.
• Battery matters. If the battery runs out and there's no backup method, the zips may stay locked. Charge it regularly, and check whether a backup key is included.
• Wet or dirty fingers. Like a phone sensor, accuracy can drop with very wet, muddy or greasy fingers. Wipe your finger dry first.
• Airport security. You may be asked to open your bag, so make sure the lock is charged and working before you get to the checkpoint.
• Details aren't fully published. Fingerprint capacity, battery life and backup options aren't listed on our product pages, and specifications vary between retailers online.

Tips for Getting the Most from a Fingerprint Lock Bag

1. Register more than one finger. Use fingers on both hands in case one is injured, wet or gloved.
2. Charge it before you travel. Top it up the night before a trip, just as you would a phone.
3. Keep the backup separate. If a spare key came in the box, store it somewhere other than the bag itself.
4. Keep the sensor clean. A quick wipe with a soft cloth keeps readings accurate.
5. Pair it with sensible habits. Keep the bag in front of you in crowds and never leave it unattended.

What Are People Saying?

These bags are newer additions to our range. The travel backpack has two reviews, the crossbody bag four and the tech pouch one and the laptop bag has none yet. Online, there's very little independent feedback on these specific models. What we can say is that shoppers searching for fingerprint lock bags tend to value the keyless convenience and the added peace of mind in crowded places, and to ask about battery life and backup access, which is why we've covered both above. If you buy one, we'd love to hear how it works for you.

WiWU Fingerprint Lock Bags FAQs

How does a fingerprint lock on a bag work? A capacitive sensor reads your fingerprint pattern and compares it with templates stored on the lock itself. If it matches, an electronic latch releases the lock-linked zips. No app or internet connection is needed.

How do I charge the fingerprint lock? Locks like this are typically charged over USB, and the crossbody spec says its lock has no user-replaceable batteries.

What happens if the battery runs out? It depends on the model. Some listings mention an emergency key, but we can't confirm this for every bag, so charge the lock regularly and check what's included.

How many fingerprints can I register? This varies by model, so please check the instructions supplied with your bag. Some retailers list up to 10 fingerprints for certain WiWU locks.

Are the bags waterproof? The backpack and crossbody bag have a PVC exterior that sheds heavy rain, but their specifications describe them as water resistant, so avoid submerging them. The laptop bag has a wipe-clean PU leather finish and the pouch uses water-resistant leather.

Will a fingerprint lock bag cause problems at airport security? Not usually, but you may be asked to open the bag. Make sure it's charged and that you know how to open it quickly.

Which laptop sizes fit? The backpack and laptop bag both take laptops up to 15.6 inches, and the laptop bag also fits a 16.2-inch MacBook Pro. The backpack is also listed as suitable for 16-inch MacBook Pros.

How Do They Compare to Other Secure Bags?

If biometric security isn't essential, there are plenty of other anti-theft options in our range:

• BANGE BG-2517 Review: a 35L backpack with YKK zips and a 17-inch laptop sleeve
• BAGSMART Expandable Anti-Theft Backpack: hidden zips and a curved back panel
• WiWU Master Pro Travel Backpack: a waterproof PVC travel pack without the fingerprint lock

Final Verdict

WiWU's fingerprint lock bags bring a genuinely useful piece of consumer tech to everyday carry. The travel backpack is the pick for most people, the crossbody bag suits crowded city days, the laptop bag brings biometric security to a boardroom look, and the pouch locks away small tech accessories. They're a deterrent rather than a vault, and they need a charged battery, but for keyless convenience and added peace of mind in busy places, they're an interesting upgrade.
