"A truck system is an arrangement in which employees are paid in commodities or some currency substitute (such as vouchers or token coins, called in some dialects scrip or chit) rather than with standard currency. This limits employees' ability to choose how to spend their earnings\u2014generally to the benefit of the employer. As an example, company scrip might be usable only for the purchase of goods at a company-owned store, where prices are set artificially high."@en . . .
