Taking to Twitter, CPI(M) general secretary Sitaram Yechury also observed that the recommendation by the panel, headed by Andhra Pradesh Chief Minister Chandrababu Naidu, comes at a time when furnishing PAN is already mandatory for transactions above Rs 50,000.
"Condemn such coercion to force people to turn digital & pay heavy transaction costs. For monitoring, transactions above 50K already has PAN," Yechury tweeted.
The Naidu-led committee on digital payments had yesterday recommended a Rs 1,000 subsidy for purchase of smart phones by non-tax assesses and small merchants and a cash transaction tax on withdrawals of Rs 50,000 and above in banks.
The 'Merchant Discount Rate' is charged to a merchant by a bank for providing debit and credit card services.
Naidu also suggested insurance for all digital transactions to safeguard the interest of people going cashless.
