German electronics company Infineon has developed a single chip for NFC applications that is helping US storage firm Kiss use a smart lock for self-storage.

In many sectors, conventional keys are fast becoming obsolete, a development that has now reached the self-storage industry. Keep It Simple Storage (Kiss) has transitioned from manual locks to fully automated and remote-controlled systems for secure locking. With the NFC-powered, battery-free smart lock from Infineon, the rental storage provider is enabling secure locking for storage locations with a smart lock.

The Kiss smart lock system lets owners and operators switch from manual locks to smart locks without the need for disruptive add-on devices such as batteries, Bluetooth or cables. The system enables instant troubleshooting and remote problem-solving, a feature not previously available in this industry.

These features eliminate common self-storage inconveniences such as auctions, lost keys and replacing locks. It also eliminates the need for operators to provide round-the-clock maintenance teams for individual lock incidents.

The smart lock is based on Infineon’s NAC1080 microcontroller (MCU), a single-chip with integrated H-Bridge for passive NFC lock applications.

“We are thrilled to introduce our new smart lock products to the world, a perfect blend of cutting-edge NFC technology and energy harvesting mechanisms,” said Robert Kapp, founder of Kiss. “These lock products not only ensure unparalleled security but also reflect our commitment to sustainability. It’s not just about unlocking doors; it’s about unlocking a future where technology eliminates inefficiencies while creating eco-friendly living environments.”

Doris Keitel-Schulz, vice president at Infineon (www.infineon.com), added: “We are pleased to see that our innovative technology can help customers develop disruptions, thereby reducing e-waste and lowering overall carbon footprints.”

The NAC1080 integrates an H-Bridge and an energy harvesting module to enable a smart actuator in a single-chip, with less components. Through the NFC interface, the MCU enables direct control of a device via a smartphone, which allows multiple storage units to be managed from a Kiss lock system. In addition, local and cloud functions can be extended via the mobile app. The device also reduces bill-of-materials and supports miniaturised product design.

The MCU supports various operation modes and can be powered either in passive mode by the NFC field with the energy harvested from the mobile phone, or through a battery supply in active mode. The NAC1080 also has an integrated AES128 accelerator and random number generator, enabling data encryption and decryption in a low-power environment. In addition to passive NFC lock applications, the NAC1080 can also be used in applications such as back-up power for active lock systems and NFC interface ICs for electronic devices.

With over 20 years of experience in owning and operating storage facilities, Kiss (www.keepitsimplestorage.com) has created technology to service and support customer needs while cutting overhead costs. By using Kiss, managers can oversee multiple store locations from anywhere. Using two-way smart video software, customer-facing mobile applications, store auto-attendants, and smart cameras and sensors, Kiss provides a package for business owners looking to step forward into the world of virtual operations.
