2004年1月，原告杨某（男）结识了被告韩某（女）。同年8月27日，韩某用手机发短信给杨某，向他借钱应急，短信中说：“我需要5000元，刚回北京做了眼睛手术，不能出门，你汇到我的卡里。”杨某见短信后立即将钱汇给了韩某。一周后，杨某再次收到韩某的短信，又借给其6000元并汇到了韩某的账户。因都是短信来往，两次汇款杨先生都没有索要借据。借了两次钱后，韩某非但没有还钱，反而继续向杨某借钱。杨某起了疑心，要求韩还钱。但几经催要，韩某只是发短信说：“我一定还，但需要等一段时间。”可韩某还是久欠未还，杨某逐将韩某告上了法庭。并提交了银行汇款单存单两张。但韩某却称这是杨先生归还以前欠她的欠款。法院审理认为，手机短信载明的款项数额、往来时间与杨某在银行的业务凭证相符，同时短信还载明了被告承诺偿还借款的意思表示，证据间相互印证，故可以认定被告向原告借款的事实。据此，法院判令被告韩某偿还原告人民币1.1万元。
