Abstract
A system and method of transmitting electronic voucher through short message. The method of transmitting an electronic voucher through a short message includes converting an electronic voucher to be transmitted into a bit stream; mapping each n-bits of the bit stream to any one text character of one of a plurality of text character groups, wherein text characters in each of the text character groups have at least one same or similar feature, and bit number n corresponding to each text character depends on the number m of the text character groups; arranging the text characters obtained through the mapping into a character sequence; and transmitting the character sequence through a short message. The present invention greatly reduces the cost for issuing an electronic voucher, significantly increases the convenience and apparently improves the safety and the stability.
