Ration cards are official documents issued by governments to help distribute essential goods, especially during times of scarcity or economic hardship. These cards allow individuals and families to purchase a limited quantity of food and other necessities at subsidized prices. Rationing is often implemented during crises, such as wars or natural disasters, to ensure that everyone has access to basic supplies. In many countries, ration cards are linked to a specific household and may include details like the number of family members. They can be used to obtain items like rice, sugar, and cooking oil from designated shops, helping to manage resources effectively.
