Will CBDC money expire?

As someone interested in the world of finance and cryptocurrency, I have a pressing question regarding the new trend of Central Bank Digital Currencies (CBDCs). With the rise of digitalization in the financial sector, it's natural to wonder about the lifespan of these digital currencies issued by central banks. Specifically, I'm curious to know: Will CBDC money have an expiration date, akin to some gift cards or promotional offers? And if so, what are the implications for users and the broader financial system? Understanding the potential expiration of CBDC money is crucial for assessing its viability as a long-term solution for digital transactions.
