This (iLOQ S5) was released in 2019. It and its predecessor (S10 released in 2007, which is a similar battery-free digital lock) are fairly popular locking systems in Finland, e.g. in apartment buildings. Their main competitor Abloy also has similar products (Abloy Pulse), along with traditional locks (e.g. Protec2). Practically all door locks in Finland are either Abloy or iLOQ.
