Digital payments and QR codes — how widely accepted are they now?

Digital payments and QR codes are growing, especially in tourist areas, larger businesses, and among younger vendors, but cash is still very much in use and often preferred for smaller transactions, markets, tuk-tuks, and rural areas. Having a mix is still the most practical approach. Some places accept cards or digital payments but may prefer or require cash for smaller amounts. It's wise to carry sufficient cash for daily expenses and have backup options. The situation is evolving, but cash remains reliable everywhere. Many travelers use a combination — digital where convenient, cash for flexibility. Notifying your bank about travel and understanding any foreign transaction fees helps avoid issues with cards.
