Infineon Makes way for Getting rid of Keys

In the near future, using keys is a thing of the past in many parts of society. Infineon Technologies AG is launching a solution on the market that can be used to open and shut locks through the mobile phone – without any batteries within the lock. The application gets the power it needs contactlessly in the cell phone. This is also referred to as energy harvesting.

\”Infineon is paving the way in which with the new solution for doing away with keys,\” says Adam White, Division President of Power & Sensor Systems at Infineon. \”By dispensing with batteries, we're providing, the very first time, a reliable, low-maintenance and secure method of frequent lowering and raising smart locks.\”

Infineon says that it will likewise put the solution for contactless energy transfer to use in other applications. \”Our solution for contactless use of energy saves resources because of the lack of batteries. Additionally, it'll enable new applications in which the utilization of batteries was once too complex or too cost-intensive,\” says White. One example is to determine parameters that are hard to access, like a NFC passive tire pressure sensor for bicycles.

To activate the lock, the mobile phone must be held on it. Near-field communication (NFC) can be used to check if the device is also actually authorized to open the lock. This is when encryption technology is available in. Simultaneously, energy is transferred contactlessly to some capacitor that opens or closes the lock.

The core from the option would be the programmable 32-bit ARM Cortex-M0 microcontroller having a built-in NFC frontend. With integrated power generation as well as an H-bridge, the NAC1080 enables customers to launch miniaturized smart locks on the market with not many components. The NAC1080 comes with an additional integrated AES128 accelerator along with a true random number generator to permit data encryption and decryption with extremely low power consumption.

The Infineon technologies are especially suitable for locks that need little mechanical effort, for example at work furniture, hospitals and fitness studios. Other possible applications are bicycle locks, mailboxes and parcel boxes. The solution thus provides greater convenience and flexibility, while at the same time cutting the costs for key management in private and commercial properties.

The new solution from Infineon can, however, also be employed in complex locking systems for example front doors. It steps in as an emergency solution when batteries in standard smart tresses are out of power, or when keys are lost. Although the response here we are at more complex door locks is longer, it does eliminate relying on an expensive locksmith service.

The marketplace for smart locks is booming. It had been valued in 2022 at $1.4 billion, and is expected to grow from 2022 to 2028, at an average annual rate of 18.2 percent, to $5.3 billion. This growth will gain even more momentum by using battery-free devices.
