NB-IoT smartlocks

TOPdigital Group NB-IoT smartlocks project

Headquartered in Malaga, Spain, Top Digital develops a multitude of activities in various sectors from telecommunications and software development to retailing and the distribution of household appliances and electronics to 40 stores in Spain.

Task - With many of TOPdigital’s customers being large enterprises, purchasing mobile phones, electronics, and security equipment from them, a demand had been emerging for an end-to-end connected smart access control solution that could also be bundled with their existing product range.

Solution Following successful trials in their offices, new access management software and apps were built specific for Spanish shops, offices, banks and hotels. Digital Keys supplied the API’s, the smartlocks and the technical support to develop the product. The smartlocks were connected to the Vodafone Spain NB-IoT network.


Benefit The product was sold to companies all over Spain bundled with TopDigital's existing products - customers included Zurich, banks and credit unions such as BBVA, universities, and a hotel chain in southern Spain.

Web self-check-in

Marysville Garden Cottages web-check in system project

Marysville Garden cottages consists of eight fully self contained accommodation cottages. Nestled in a garden setting a short drive from Melbourne, Australia and at the edge of the Australian snowy alps, the accommodation is popular with adults for mountain biking, hiking in summer  and skiing in the winter months.

Task - Before construction had begun of the cottages in 2013, the owner Anthony Slot approached Digital Keys with the brief to build a web self check-in system, so that he didn't need to design and build a managers office/reception desk on site, and employ a full time Receptionist.

Solution - If a potential guest arrives unannounced at the unmanned cottages, they check themselves in through Garden Cottages website and then they automatically receive a receipt and a door code within a minute after their credit card payment has been approved so they can go straight to their room and enter the door code as their room key to enter. At check-out time the code expires, and the guests go on their way. The system also integrates with Online Travel Agencies, and interfaces to smartlocks with numberpads (see lock in image opposite)


Benefit The system saves the managers hundreds of thousands of dollars a year in not having to staff a reception desk, and it makes management of the cottages efficient with the Manager being able to keep his day time job as a builder.

Digital Keys App

Aruba Beach Resort Digital Keys App project

Based on the Gold Coast in Australia, Aruba Beach Resort is a 3 star-rated three-storey walk up resort apartment building ideally situated only 200 metres from the beach, Casino and Gold Coast Convention and Exhibition Centre. Resort rooms have fully equipped kitchens and private balconies.

Task - The owners of the Resort had been using metal keys for room access since the resort was built in the early nineties and they had grown sick of paying locksmiths $150 to come out and replace locks atleast once a week from guests who had lost their keys, or forgotten their keys.

Solution Digital Keys built a self check-in app and system which enabled guests to self check-in on their phones and receive a unique time-sensitive code emailed to them to unlock their rooms. The guests were able to change the code to something they could easily remember like their bank PIN code. This way the guests just had to remember their PIN and enter into the numberpad locks on their room doors (and common doors) to let themselves in.  Guests liked the fact that they did not have to carry around metal keys to access their properties.  


Benefit The managers who live on site were happy to be able to sleep fully through the night again as they never had to get up to let in guests who had locked themselves out in the middle of the night. The cost savings from not having to pay locksmiths to come out to replace the locks quickly added up.
