Pros of a Cashless Society
Convenience & Speed
Digital payments are faster than handling coins or bills.
Reduces time spent in lines or at checkout counters.
Reduced Crime
Less physical cash means fewer robberies and less street crime.
Harder for criminals to hide or launder money.
Improved Tax Compliance
Digital transactions are traceable, reducing tax evasion and black-market activities.
Efficiency in Transactions
Easier for governments to distribute aid, subsidies, or benefits digitally.
Businesses save time and costs on cash handling and banking.
Better Financial Data
Digital records help consumers budget and track spending.
Governments and companies can better analyze economic trends.
Public Health
Reduces the handling of potentially dirty cash—important during pandemics like COVID-19.

Cons of a Cashless Society
Exclusion of Vulnerable Groups
Elderly, low-income, or rural populations may lack access to digital tools or bank accounts.
Can worsen financial inequality.
Privacy Concerns
All transactions are traceable, raising fears of surveillance or misuse of personal data.
Cybersecurity Risks
Increased risk of hacking, identity theft, and financial fraud.
System outages can disrupt access to funds.
Dependence on Technology
Requires internet, electricity, and devices—disruptions can freeze the economy.
Natural disasters or blackouts can halt transactions.
Fees & Control by Financial Institutions
Payment processors or banks may charge transaction fees or impose limits.
Shifts financial control from individuals to institutions.
Loss of Anonymity
Cash offers privacy; digital payments don’t.
Sensitive purchases could be tracked or judged

Personally, none of the "pro's" would provide me with any notable advantage, although there are several "con's" which concern me. The fact that low-income rural families could be in trouble if Thailand were to ever become totally cashless is of course a concern, and should of concern of everyone's. Security against identity theft, hacking, fraud, etc., would be another significant concern.
Not to fret...as mentioned before, cash and cashless options will be available to everyone here for at least our lifetimes.
