In comparison to electric motor-driven locks (note: all our locks are electric motor-driven), solenoid, or electromagnetic, locks have good holding but rather poor pulling force (force to power ratio). This makes them somewhat sensitive to vibrations, e.g. door slams, and may also cause difficulties in proper functioning. When there is too much pressure/force/tension on the locker door from the inside the locker (e.g. a large bag inside or when locker is jam-packed) solenoid locks can have problems to unlock on its own, without the human interaction.

If by “best” you mean the most remote a.k.a. convenient way for a locker user to unlock his/her locker, that would be a mobile app, which operates as a locker “key” via Wi-Fi of mobile network. A smart locker with such smart locker keys via wi-fi, can be basically unlocked from anywhere the locker user wants to (you could unlock your office locker from the exotic vacation half way around the world, if you need to).
With such wi-fi unlocking, an RFID reader is not required to unlock the lockers. Such truly mobile smart locker solution saves you money (no RFID readers). Sometimes even more importantly, it enables the fully clean-line visual appearance of locker doors and the locker bank. Something you and especially your workplace interior designer can appreciate when refurbishing your office space.

The second best option, range-wise, is via Bluetooth, whereby lockers can be unlocked with a mobile app, via Bluetooth, when users are within range of the Bluetooth signal from the reader on the locker bank (up to 10 meters/30 feet away, depending on the strength of the BT signal).

NFC (Near Field Communication) doesn’t really provide “remote” locker usage as users have to be within 1- 4cm from a reader, which is basically the same as with normal RFID cards. It does take away the necessity to have a card on you, to unlock your locker (that rarely happens with your mobile phone, right?)
Also, wi-fi, mobile network and Bluetooth technologies are all included in every new smartphone on the market today, which isn’t always the case with NFC.

In short: Yes. Our smart electric motor-driven locks offer different locker door dynamics (what happens with the locker doors once the lock unlocks the locker):

– Spring open
– Push to open (gentle push on the locker doors)
– Pull to open (with the locker handle)

The first two locker door dynamics do not require locker doors to have handles and are usually user for our smart locker solutions in various workplaces and in public, educational, leisure and sport facilities (Spring open locker door dynamics is also the preferred choice for parcel lockers). Both locker door dynamics have also a Push to close dynamic.

The Pull to open mode requires locker handles. With self-closing hinges the locker doors can also self-close (and re-lock). The mode is usually used with lockers, which need to maintain the temperature within the locker.

Yes. Our locks can be mounted at any degree you prefer, to provide you with the locker door opening direction of choice.
“Z” shaped 2-tier lockers with our locks actually open to the left (left door) and to the right (right door).

The majority of new smartphones need min. 1A of power to recharge, whilst tablets require even more, ca. 2-2.5A. Some locks do have a built-in USB charger, but they normally provide only up to 500mA of power. This means that, at best, it takes a long time to recharge devices, plus there is a certain electric risk if too many users try to charge their phones and tablets on the same locker installation/electrical grid at the same time.
We suggest a different solution to our smart locker solution clients, which by our opinion, and their feedback, is better, safer and more user-friendly.
