Workplace lockerselectronic locking system

The Metra electronic locking solution for workplace lockers supports all major RFID smartcard standards as locker “keys”: LF, ISO 15693, ISO 14443A and 14443B (different brands, e.g. HID iClass™, Seos™, Mifare™, DESfire, LEGIC, Sony FeliCa, CEPAS, SRx, etc.). In short, with the Metra electronic locking solution the locker users (employees, interns, visitors, etc.) can use their employee access cards also for various electronic lockers in the workplace (personal lockers, agile lockers, departmen lockers, project lockers, office mail drop-off / pick-up lockers, bicycle lockers, shower lockers, etc.), regardless of which RFID standard your organisation already uses, or will use, for access control.

In addition to RFID media, barcodes, QR codes, PIN codes or fingerprints can be used as locker keys. More secure, two-level locker access security is ensured in combination with RFID cards/tags. The Metra mobile app MyMetraKey is also a very popular and innovative option for workplace locker keys, as it makes locker interaction (unlocking, opening, booking a locker etc.) even simpler, by enabling users to manage their lockers remotely, on-the-g0, from virtually anywhere in the world.

Patented Metra electronic locks can be easily fitted into existing or new lockers, with any locker material (wood, HPL, metal,..) and are also fully hidden from direct view or access, thus preventing vandalism and break-in attempts. The opening/closing modes of Metra electronic locks even make locker handles redundant, providing a clean locker door design. This provides both security and beauty when it comes to your workplace lockers. Metra electronic locking is a highly reliable, secure and user-friendly system and solution, which avoids visually interfering with your beautiful office or workplace lockers.

The Metra with Genuine HID Technology™ solution allows organisations to leverage existing HID™ credentials for broader workplace solutions and to move them toward a connected environment built around mobility. Organisations, which use, or will use, HID™ access control solution (iCLASS, Seos, Prox, Indala,…), can easily extend HID™ security level and credentials to all their workplace lockers. Employees use their personal HID™ access control smart card media for equally secure and user-friendly use of their workplace lockers.

With HID Seos access control system, employees can use their HID Seos™ smart card, the HID Mobile Access™ mobile app or a combination of both.

With the Metra mobile application MyMetraKey locker users can remotely unlock, open and manage their electronic lockers from anywhere in the world. The MyMetraKey app can be used as a sole locker key or as a secondary locker key (in addition to RFID media, e.g. an employee card). Users do not need to carry RFID media with them at all times or to search for it in a hurry when needed. Instead, they can just use the MyMetraKey app on their phones.

If you want to see your high-end, high-quality modern, clean design, electronic office lockers in full, using the MyMetraKey app is the way to go. Apart from fully hidden Metra electronic locks and redundant locker handles, no RFID user interface (RFID reader) is needed. All you see are the locker doors of your high-priced locker banks.

The MyMetraKey app is compatible with all existing or new Metra electronic locking systems and is available on Android and iOS.

“The Metra electronic locking system, nicely and flat mounted in the locker wall, is very easy to use solution for our office lockers on multiple floors. The ability to use office storage lockers with our existing access cards or our finger prints is very convenient. The solution is working flawlessly and without any maintenance at all. Sometimes visitors don’t even notice that they walk by a wall of lockers :).”

Frank Laven, Facilities Coordinator, Unit4, global software company

“1000+ agile office lockers in our HQ are equipped with the Metra locking solution. Employees use existing access cards to assign nearest vacant lockers via touch screen. Metra locker management software provides us with an instant overview of each locker user activity over multiple floors in real time. We especially like totally “clean” look of our locker banks due to concealed Metra locks.”, leading webstore, Netherland


Of course. Metal, HPL or other type of lockers can be easily retrofitted with one of the Metra electronic locking solutiosn. In the process of retrofitting the lockers, the existing locks can be removed or left on locker doors.

In short: Yes. However, it is necessary to choose an open/close combination. Metra electronic locks have three open/close modes or combinations to choose from, depending on your locker installation requirements and needs:

– Auto-open/push-close
– Push-open/push-close
– Pull-open/auto-close

The first two modes do not require locker doors to have handles.

In comparison to motor-driven locks (note: all Metra locks are motor-driven), solenoid locks have good holding but rather poor pulling force (force to power ratio). This makes them sensitive to vibrations, e.g. door slams, and also causes difficulties in proper functioning when there is too much force (tension) on the door from the inside (e.g. a large bag inside a locker).

If by “best” you mean the most convenient way/technology for users to operate lockers, then we would suggest WiFi/4G, for a number of reasons. With WiFi/4G electronic lockers can be opened from anywhere (yes, from anywhere in the world, where your mobile phone has a network signal). Secondly, a user interface is not required to open lockers which a) saves you money, and b) enables the visual appearance of locker installations to stay intact or “clean” (no RFID readers).
The second best option in our opinion is using Bluetooth, whereby lockers can be opened when users are just a couple of metres away from a Bluetooth user interface/reader, still within range of a Bluetooth signal.
NFC (Near Field Communication) doesn’t really provide “remote” locker usage as users have to be within 4cm of a NFC user interface, which is basically the same as with normal RFID cards.
Additionally, Wifi, 4G or Bluetooth technologies are all included in every new smartphone on today’s market, which isn’t always the case with NFC.

The majority of new smartphones need 1A of power to recharge, whilst tablets require even more, ca. 2-2.5A. Some locks do have a built-in USB chargers, but they normally provide only up to 500mA of power. This means that 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. A separate cabling for charging purposes is probably a better (and safer) solution.
