Workplace lockerselectronic locking system

The Metra locker system 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 locker system the locker users (employees, interns, visitors, etc.) can use their access cards for various electronic lockers in the workplace (permanent lockers, activity-based lockers, group lockers, project lockers, office drop-off/pick-up lockers, End-of-trip lockers, etc.), regardless of which RFID standard your organisation already uses, or will use, for access control.

In addition to RFID media, other options, e.g. PIN code, barcode, QR code or fingerprints can be used as locker keys. The Metra mobile app MyMetraKey makes smart locker interaction (remotely unlocking, opening, booking a locker etc.) even simpler. Locker user can manage his/her locker on-the-g0, from virtually anywhere in the world.

Patented Metra locks can be easily fitted into existing or new lockers, 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 locker system avoids visually interfering with your modern, clean-line 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 user can remotely unlock, open and manage his/her workplace locker from anywhere in the world. The app can be used as a sole locker key or as a secondary/tertiary locker key (beside an employee access card). No need to have access card with you all the time.

When app is used as a sole locker key, it also provides fully clean-line locker banks, so you can see your high-end lockers in their full beauty. Apart from fully hidden Metra smart locks and redundant locker handles, also no RFID reader is needed. All you see are the fully “clean” locker door panels of your workplace locker banks.

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

Metra listened to what we believed to be achievable and provided a system capable of providing exactly what we wanted to achieve. So many features yet so simple to operate. Building services cards were reduced from three to one. The support provided by Metra has ensured the smooth operation of the locker system.

Ray Marsh, Senior Facility Manager, Mirvac Operations, Australia

“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.

Yes. There are three types of Metra smart locks to choose from, depending on your, and your locker users, wishes, needs and requirements:

– Auto-open/push-close (usually used for delivery & Pickup workplace lockers)
– Push-open/push-close (usually used for storage workplace lockers)
– Pull-open/auto-close

The first two lock types do not require locker doors 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 RFID access 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.
