Featuring renowned specialisation in solutions for public transport, we provide solutions for access control, loyalty and security, alongside others security.

Public transport

With a growing percentage of the world’s population living in urban areas, we are committed to the sustainable development of cities through mobility solutions with public transport for social, environmental and economic reasons, working to improve citizens’ quality of life.

At the forefront in the introduction of the first magnetic tickets for access control, we have accompanied and led the migration to contactless technology, swifter and safer, on many train, bus, tram and metro projects.

Offering solutions in various formats and technologies, our partnerships with system integrators enable us to ensure the functionality of our products for the most widely used access control systems.

The construction of safe, quality and environmentally friendly roads involves a high cost that is often covered by the installation of tolls that collect payment from the users who journey on them. Magnetic tickets are an optimal solution for closed tolls: when accessing any of its entrances, a ticket is issued that records said entry, and is delivered and validated at the exit where the amount is paid according to the length travelled.

The most common format being the roll or the fan fold, the magnetic banknotes can be manufactured in different cards and with different types of magnetic strip, depending on the equipment installed on the toll, guaranteeing compatibility with them.

Car parks

Traffic congestion in large cities is also evidenced by a lack of public parking space, a fact that causes a constant growth of the private parking market. Likewise, as the mobility of citizens increases, the need for parking space in airports, train stations, shopping centres and retail parks, hospitals, etc…

At Calmell Group, we manufacture all types of banknotes, magnetic or not, on standard paper support, thermal or laminated composites, in different thicknesses and finishes. We also bet on hybrid or contactless parking tickets, which can also be used for access to the public transport network, as is the case of tickets used in the P+R in France (“Parc Relais”) : car parking, located on the outskirts of a city and intended to encourage drivers to access the city centre by public transport: metro, tram, suburban train or bus, which allows them to park their vehicle avoiding urban traffic.

Identification & Access Control

Access control systems are present daily in our lives and increasingly encompass RFID solutions to improve the user experience and enable faster and more secure transactions. Amongst the most commonly founds solutions we have:

  • Sport and leisure: ski passes for ski resorts, membership cards for sports clubs (football, gyms, swimming pools and theme parks).

  • Culture and business: smart tickets for museums, concerts, fairs and congresses.

  • Hotels: access cards with magnetic strip or contactless for benchmark hotel chains in the sector.

We also provide solutions for personal identification, such as health card, citizen card and student card, among others. These may require security management and digital identification based on PKI systems (Public Key Infrastructures), in clients such as Certification Authorities, Public Administration and Health and Education.

Customer loyalty cards

There are many alternatives for customer loyalty, solutions designed by companies to provide their customers with a series of benefits, usually discounts, tailor-made offers, point programmes, and that gather information regarding their purchasing habits for future marketing campaigns. Of all of them, the most used is the loyalty card, being used in large clients such as:

  • Supermarket chains.

  • Fuel.

  • Airlines, car rental.

  • Business premises.

In most cases, the sending of these cards is accompanied by an explanatory letter about the benefits of the same, a service that Calmell also offers (letter printing, enveloping, mailing, …).

Smart Cities

Cities are hubs for innovation and knowledge, drivers of economic growth, prosperity and social well-being, and making them “smart” is nothing more than the result of connecting them physically and virtually in the face of the increasingly imperative need to place the well-being of citizens and respect for the environment at the centre of urban transformation to move towards a sustainable and better future.

Two fundamental pillars of smart cities are mobility and the environment. We are committed to the development of public transport as the main axis and we also participate in bike and car sharing projects through readers and contactless cards, the same solutions we offer to the growing industry of charging stations for electric cars. We offer solutions for recycling and waste management and recovery, which can also be controlled and enhanced through RFID technology.
