Contactless technology reinvents daily reality


More and more people now use a mobile phone with digital ID functions, based on contactless technology that makes it easier to take public transport, pay for purchases or reserve tickets for shows. Providing access to a growing array of new services, mobile ID enabled phones are on track for sustained development around the world. Safran is very experienced in this special technology, being a global leader in the development of mobile identity solutions, making life safer and easier.

Contactless data exchange

Seoul, South Korea, 6:15 am. On this cold winter morning, Yon leaves her apartment for the office in Gangnam. This young woman from the province of South Jeolla has been living in the capital for a year, and loves its modern look and pace of life. At 6:20 am, she takes the subway, holding her smartphone to quickly pass through the turnstile.

Modernity in Seoul also means doing everything with your mobile phone.

Mobile digital ID technology, embedded in the SIM card, is already widely used in South Korea. It allows contactless data exchange between a mobile device and a terminal (or between several mobile devices).


While Yon doesn't understand all the technology involved, she quickly grasped the advantages of digital mobile ID, and uses her smartphone with contactless technology morning to night.

For example, to enter her office building, validate her swimming pool subscription, pay for her take-away lunch, use discount coupons, etc. Not to mention that afternoon, when she suddenly decides to reserve a ticket at the National Museum of Korea to see a new exhibition on traditional Buddhist art...

Contactless technology makes your phone the unique tool to:

  • Take the subway

  • Make payments

  • Access a building

  • Visit an exhibition

  • Issue personalized coupons

  • Benefit from tele-healthcare service

In other words, digital ID technology allows the mobile phone to act like a contactless chip, storing encrypted information to make payments, gain access, issue personalized coupons and much more.

At the end of the day, following her last business appointment, Yon exchanges her e-business card with that of her customer. This function is provided by contactless technology as well, enabling data transfer between two phones.

Info at your fingertips

After leaving the office she goes "shopping" in the subway, using the Home Plus order wall. With her smartphone, nothing could be simpler: she just scans the codes for the products she wants to buy online and have them delivered to her home that evening.

But first, she uses a contactless function to read the labels and find out more about each product's traceability, carbon footprint, consumer opinions, etc. That evening at the museum, she again uses this scanner function to learn more about the traditional Tibetan Buddhist paintings, "thangkas".

High security

Yon knows that she saves time every day thanks to her smartphone with the digital ID enabled SIM card.

The SIM card ensures secure transactions and data storage

The SIM card is the most secure part of a mobile phone, thanks to embedded encryption and encoding. Transactions are secure, as is the storage of ID and bank data. Furthermore, the short distance between devices greatly reduces the risk of data theft.


Back from her museum visit, Yon welcomes the Home Plus delivery man and puts away her groceries. Then she calls her mother, in Busan.

Her mom tells Yon that she uses mobile ID technology too, but for her healthcare. Today, for instance, her doctor could directly see the results of her latest tests, using his smartphone. And that makes it much easier to prepare for the next doctor's appointment.
