In my opinion, whether the use of credit/debit cards is popular or not depends on how quickly CBDC is adopted among the public. However, I think that although CBDC provides many conveniences, its level of popularity will probably take several years to come. And currently, perhaps the use of credit/debit cards is still very popular and still needed among the public.
CBDC probably gonna take advantage fully of the fact that the issuer is the law maker, you know the government could easily introduce CBDC and just let people use it for digital transaction sort of using e-money which many countries right now are starting to use.
the presence of CBDC will probably not gonna disrupt debit card or credit card at all it has its own niche and the fact that these cards could be used for transaction internationally and is accepted in most of e-commerce not gonna get fazed by the existence of CBDC.
Millions still use actual cards. Not everyone is tech-savvy or has fast internet. Converting everything to digital takes time. Security is another issue. This is digital money, therefore we need to authenticate identities without compromising convenience or opening the door to hackers. This is significant stuff we can't ignore
Remember Visa and Mastercard, the big boys. These guys won't leave soon. They've got the money, experience, and infrastructure to adapt. They may even become CBDC transaction facilitators or security consultants. The key is, they won't surrender. CBDCs might be the future, but the shift won't be easy. There are many moving elements and significant challenges to address. But it's also about how we connect that technology into our existing systems, assure security and convenience, and adapt to a quickly changing financial world
CBDC if truly released, I guess at best gonna just be disruptive toward the stablecoins though, from where the CBDC value gonna get derived if not from the fiat, the entire mechanism resembles stablecoin and yes I think so too probably these CBDC already designed to work together with those debit cards and credit card pretty sure the entire system probably gonna get integrated with banking system.
