Our Case Studies

We've been making smart locks and digital keys since 2011

NB IoT smart lock installation

Top Digital Office Building, Malaga Spain

The TOPdigital Group develops various activities in the sectors of telecommunications, energy efficiency, consulting, marketing, household appliances, home and professional equipment, entrepreneurship and software development.

With over 500 employees, TOPdigital Group were looking for a solution to secure and control access to offices, meeting rooms, and server rooms.

As one of Spain's top retailers for mobile phones it was important for TOPdigital Group to implement a solution that was consistent with their brand.

10 locks were installed in the Top Digital Headquarters in Malaga, Spain for a two month trial.

LEAPIN Digital Keys also worked with TOPdigital group to implement the NB IoT smart access API so that customerised apps and software (in Spanish) could be built.


TOPdigital were so happy with the Digital Keys NB IoT solution, that they signed a Distributor agreement to sell the product to other offices in Spain, as well as hotel groups and construction companies.

Manufacturer Smart Lock SDK

SAG Lock Manufacturers, Germany

SAG, a European lock manufacturer with over 180 years of experience in the lock manufacturing industry, added mobile check-in SDK (with NFC and one-time password technology)  from LEAPIN Digital Keys to their existing range of electronic locks. The new solution enables guests to self check-in to their hotel accommodation, bypass the reception desk, and unlock their doors with their smartphone.

SAG concentrates its production and service activities on highly developed components, systems and solutions for the locking and organisation of buildings.


The company operates globally and is active in three business areas: lock and striking plate systems; locking systems for doors and furniture and guest management systems.

In 2015, the company started adding LEAPIN Digital Keys mobile check-in SDK to their lock range. 

Today, the quick and easy check-in from home or the road forms part of the contemporary amenities of modern hotels for business and leisure guests.

Future-oriented hotels are therefore digitalising the processes relating to reservations or reception and even including the smartphone as door opener. This gives more time for the service personnel to care for the guests. With the locks offering a mobile check-in solution, guests can check-in completely without involving personnel by means of smartphone.

In the first 2 months after launching mobile check-in, SAG sold 3000 units to 4 hotel groups in Germany.

Revenue's for one of their lock models increased 40% year on year after adding LEAPIN Digital Keys mobile check-in. Mobile Check-in also opened up new sales opportunities such as in municipal swimming centres.

Accommodation web check-in with digital keys 

Marysville Garden Cottages B&B, Australia 

Marysville Garden Cottages, a short drive from Melbourne Australia, engaged LEAPIN Digital Keys to build a fully automated web check-in system so they did not need to build and staff an onsite reception desk when they opened in 2013.

These 8 beautifully detailed guest cottages are specially designed by the owners to have a relaxed country feel with plenty of luxurious touches.


The cottages are set among an ornamental garden with Marysville Village at your doorstep. Catering for couples, singles, or groups, all have a cozy gas log fire and a private garden veranda with mountain views.

Before construction had begun of the cottages, the owner Anthony Slot approached LEAPIN 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.

After making the booking on the accommodation website, or at any Online Travel Agency, the guest automatically receives an email with an access code to enter their cottage which they use as a key by entering into a smart lock numberpad on the door to gain entry. The code only works for the duration of the guests booking. This eliminates the need for traditional check-in, and satisfies the guests who should wish to arrive late at night or just keep to themself.

Not only is the owner happy with all the money he saved by not having to build a managers office, but he also saves money every week by not having to pay wages to an onsite manager.

"The LEAPIN Digital Keys system has saved us loads of time and money. We are very proud to be your first property to use the system"

Anthony Slot - Owner, Marysville Garden Cottages.

Hotels and Resorts Digital Keys Apps

Aruba Beach Resort, Australia

In 2011, LEAPIN Digital Keys installed Australia's first self-check-in app with digital keys in Aruba Beach resort on Australia's sunny Gold Coast. The app was used to book rooms, and to receive a time-sensitive digital key in the form of a time-sensitive access code without the need for any human interaction.

The owners of Aruba Beach Resort in Broadbeach on Australia's Gold Coast, were paying locksmiths $150 to come out and replace locks about once a week from guests who had lost their keys.

Another regular ongoing expense was paying whats the owners called a "night service" to answer calls after hours (the reception desk was only open 9am-5pm) to inform the guest of a keycode to a safe/lockbox installed on the wall in front of the resort, which they had to open to get their metal key.

With the resort only meters from the beach, and with its own swimming pool, resort guests liked the fact that they did not have to carry around metal keys to access their properties.  Instead they just had to enter a code into a numberpad on the door. They could even change the code to something they could remember easily like their birthdate.
