Looking for NFC/BLE P2P wearable

[WarhogWearable]

My partner and I are creating an app designed for P2P as well as traditional user/vendor interaction. We need a wearable that can create a mutual event on the back end when the two wearables touch or are in close proximity. I see the ST25R3916 or STM32 chips may be suitable but wondering if there’s already a wearable with these capabilities or if one can be designed/created that’s suitable for kids. I also see there’s a wearable - STEVAL-WESU1. Can the STM32 be used in the WESU1? I have additional requirements, like haptics, visual indicators, etc, that I can provide info on but I can’t find a wearable that can create a P2P event. Any help is appreciated

Hi @WarhogWearable ,

The ST25R3916 NFC reader combined with an STM32 MCU is suitable for enabling P2P event detection via wearable devices. The STEVAL-WESU1 includes an STM32 MCU but does not natively integrate the ST25R3916, though external NFC modules can be added. Currently, no off-the-shelf wearable specifically supports P2P event creation for kids, so designing a custom wearable with NFC, haptics, and visual indicators is recommended. Prototyping with ST25R3916 and STM32 development boards is a good starting point.
