This document discusses plastic cards and electronic banking. It defines plastic cards as electronic cards issued by banks that allow 24/7 access to accounts. The main types are debit cards, which access available account balances, and credit cards, which allow spending beyond balances up to credit limits. Electronic banking is defined as transferring funds electronically between financial institutions rather than with physical cash or instruments. It offers conveniences like accessing accounts remotely but also risks like electronic fraud. Advantages include convenience while disadvantages include learning curves and potential system issues.
