low energy rf air tag Key Facts and Findings. Uses off the shelf components, apart from Apple’s U1 chip for UWB. The popular nRF52832 is used for BLE and NFC. Sleep current consumption of 2.3µA gives over 10 years of potential battery life. Updates BLE address and public key once a day at 04:00am. Updates last byte of advertisement data every 15 minutes.
A contactless smart card is a contactless credential whose dimensions are credit card size. Its embedded integrated circuits can store (and sometimes process) data and communicate with a terminal via NFC. Commonplace uses include transit tickets, bank cards and passports. There are two broad categories of contactless smart cards. Memory cards contain non-volatile memory storage components, and perhaps some specific security logic.

The Apple AirTag uses Bluetooth Low Energy (BLE) to signal its whereabouts to nearby Apple devices. When you need to narrow down its location, it can also turn on its Ultra-Wideband (UWB).
It could allow for ultimate energy saving home automation, turning off all appliances in rooms in which there are no beating hearts — assuming everyone in your family is Apple . While the power delivered from Wi-Fi is very low, so too is the power drain of an AirTag. When you think that a button battery can keep it powered for a year, then it’s clear that the power .
The team worked each chip into an RFID tag with a standard radio-frequency antenna. In a key step, the researchers built a simple circuit around the memory chip, enabling the chip to switch to a local energy-assisted mode only when it senses a certain stimuli. Paragon ID is pleased to introduce revolutionary battery-less Bluetooth Low Energy (BLE) and Ultra-Wideband (UWB) sensor technology featuring an unrivalled 20 metre radio frequency (RF) energisation range, twice that of any other tags on the market.
