Is RFID a Part of Your Skincare Routine? Maybe it Should Be!
When it comes to skincare, RFID may not be the first thing that comes to mind, wrinkle cream and moisturizers is what comes to mind, but Clarisonic, a division on L’Oreal, is looking to change that.
They recently decided to use high-frequency (HF) 13.56 MHz RFID technology in order to allow their motorized Smart Profile skin-cleansing device to communicate with a brush head installed in the unit, determining when it will need replacing.
Clarisonic had been looking for an automated solution because they noticed that customers were using their brushes long past the recommended replacement date, proving to be unhygienic and ultimately, losing revenue on new brush sales.
In order to automatically track how many times the brush head was used and then alert the customer, Clarisonic needed a non-contact, water-resistant system. For these reasons, they chose RFID, testing both LF and UHF solutions before deciding on the HF solution.
The HF solution allowed for low cost readers and the ability to incorporate a decent sized reader antenna into the device’s handle for the ideal read range.
The RFID tag is encoded with both a unique ID number and data regarding the type of brush head used. The device uses this information to choose which speeds and pulse settings to make available to the user. In addition, the tag’s memory records the number of minutes that the brush has been used.
Once the brush reaches the end of its life based on the number of minutes used, the reader alerts the consumer by illuminating the device, warning them that it’s time for a replacement brush.
This is a great example of how RFID can be used to connect consumers and their devices.
