LiteHow to choose a smart locker: the 12 criteria of a solid specification
Smart locker brochures all look alike: elegant doors, a mobile app, a promise of modernity. It is when you sit down to write the specification that the real differences appear — and they are considerable. Here are the 12 criteria that separate a successful project from a decorative cabinet, in the order in which the questions should be asked.
Flows first, hardware second
1. The flows to cover
Criterion zero, the one that governs all the others: what must your locker handle? Inbound parcels only? Mail and registered letters? IT equipment handover? Flex office day lockers? Outbound shipments? List the flows, their real weekly volumes (measure for a week — do not guess) and their proof requirements. A serious supplier will start with this question; be wary of the one who starts with the catalogue.
2. Compartment types and capacity
Your volumes determine the number of compartments; the nature of your items determines their size (envelopes, standard parcels, bulky parcels, laptops). Plan for modularity: a system that extends module by module avoids repurchasing an entire bank in two years. Also check for dedicated compartments and dynamic allocation — the same compartment serving several successive recipients, which divides the capacity requirement.
3. The traceability software — the real subject
A locker without a platform is a cupboard with locks. Examine: item registration (scanning, assisted capture, labels), multichannel notifications (email, SMS, WhatsApp, Teams) and automatic reminders, proof of handover (timestamp, identification of the person collecting), multi-criteria search and complete history, reporting (volumes, occupancy rates, collection times). Ask for a demonstration on your own use cases, not a guided tour of the menus.
4. Integrations
The system will live inside your application landscape. Insist on: synchronisation with the company directory (LDAP/Azure AD) so that recipients and rights follow HR movements; open APIs; where relevant, carrier integration for outbound flows and ERP connection for reconciliations. Manual directory re-entry condemns the project in the medium term.
Then the technical architecture
5. Wired or autonomous Bluetooth
A structural question for both budget and timeline. The wired locker (power + network, touchscreen) excels in high-traffic lobbies with self-service deposit. The autonomous Bluetooth locker — battery lasting several months, no connection of any kind — installs with no building work, costs 2 to 3 times less and can be placed anywhere. Many projects mix the two; what matters is that a single platform drives them all. Our detailed comparison will help you decide site by site.
6. Battery life and maintenance
For battery-powered models: what is the real battery life (the best reach 8 months), how long does recharging take, and what level alerts appear in the supervision console? For all models: what does the maintenance contract cover, with what response times, and are software updates included?
7. IT security
Your IT department will ask these questions; anticipate them in the specification: encryption of exchanges, one-time codes, impact on the internal network (an autonomous locker never appears on it; an independent 4G terminal avoids any integration file), data hosting location (France/EU for many organisations), GDPR compliance, penetration tests and third-party assessments of the vendor. We have devoted a full article to IT department requirements.
8. Robustness and aesthetics
Quality of locks and frames, open-door detection, resistance to intensive use. And appearance: in a headquarters lobby, the locker is an architectural object — custom finishes, bespoke wood cladding and branding in company colours must all be possible.
Finally, the economic and human equation
9. Total cost, not the price of the cabinet
Compare on total cost: hardware, any building work (zero for autonomous models), software subscription, maintenance, operations. Subscription models over 3 to 5 years, updates included, make comparison easier and avoid capital lock-up. And set the gains against it: staff time, losses avoided, disputes defused — our ROI calculation method details this exercise.
10. Multi-site scalability
If you have several buildings or sites: a common database, items recognised from one site to another with no re-registration, consistent deployment, a consolidated dashboard. Equipping the pilot site is easy; it is the roll-out that tests the architecture.
11. Support and vendor longevity
How long has the solution existed? Are its first clients still on board? Does the vendor control its own code (in-house development or an assembly of third-party components)? Who provides training, configuration and support — and in what language? A locker project lasts ten years; choose a partner who will still be there.
12. The employee experience
The final arbiter: collection must take less than thirty seconds, at any hour, with no instruction manual. Test the real journey — notification, identification, opening — with unprepared users. A system that employees work around is a failure, whatever its technical merits.
The scorecard in summary
Weight these 12 criteria according to your context: a headquarters will weight aesthetics and experience; a multi-site manufacturer will weight integrations and scalability; a security-sensitive organisation will weight security and hosting. But one constant remains: successful projects are chosen on the software and deployed on installation simplicity — two criteria invisible in catalogue photos.
FAQ — choosing the right smart locker
Do you need a formal tender process?
Above a certain amount, or in the public sector, yes. But even in a simple consultation, formalise the 12 criteria above into a weighted scorecard: it is the best antidote to the demo effect (a beautiful screen makes you forget a missing directory integration). Demand written, point-by-point answers — the silences in a technical proposal are as instructive as its promises.
How do you compare offers with different scopes?
Bring everything back to total cost over the contract term (3 to 5 years): hardware + building work + software subscription + maintenance + operations, for an equivalent functional scope. A "cheap" locker without traceability software is not comparable to a complete solution — add the cost of the missing software or remove the offer from the comparison.
Is a pilot essential?
Strongly recommended: one site, three months, indicators defined in advance (volumes handled, average collection time, incidents, satisfaction). The pilot validates the sizing, reveals the edge cases (oversized parcels, visitors, temporary staff) and produces the figures that de-risk the general roll-out. Autonomous Bluetooth lockers lend themselves well to the exercise: installed in a day, movable if the initial placement proves sub-optimal.
Which contract clauses deserve particular attention?
Four points: reversibility (recovery of data and histories at the end of the contract, in a usable format), availability commitments for the SaaS platform, terms for expansion (adding modules, sites, flows — at what price?), and ownership of any bespoke developments. A locker contract is a software contract: negotiate it as such.
ISITEC INTERNATIONAL meets these 12 criteria with one distinctive trait: everything is designed in-house — the ISITRAC 360 suite (100% French, since 2010, first clients still active) as well as the lockers, from the standard model to the autonomous Bluetooth Locker Lite with no building work. Ask for our specification template or a demonstration on your own flows.
