技术领域technical field
本发明涉及计算机技术领域，尤其涉及一种POS机自动解锁锁定的方法及系统。The invention relates to the field of computer technology, in particular to a method and system for automatically unlocking and locking a POS machine.
背景技术Background technique
当前POS设备一般在操作员签到之后，任何人均可以操作POS机，包括刷卡交易、撤销交易、转账和查询流水等各种操作，存在安全隐患。At present, after the operator signs in on the current POS device, anyone can operate the POS machine, including various operations such as swiping the card, canceling the transaction, transferring money, and checking the flow, which poses a security risk.
这样某些不法分子可能会利用这个漏洞先消费，后再到店内秘密撤销此前的刷卡交易业务，进行骗取商家财产的违法行为。In this way, some criminals may take advantage of this loophole to consume first, and then go to the store to secretly cancel the previous credit card transaction business, and carry out illegal acts of defrauding the merchant's property.
甚至此前发生过这种案件，即违法人员以刷卡套现并给予好处费为名骗取商家信任，先持信用卡到商家店铺刷POS套取现金，进而偷偷潜入店里秘密操作POS机撤消该笔业务，窃取商家财产。There have even been such cases before, that is, the illegal personnel defrauded the trust of the merchant in the name of cashing out by swiping the card and giving the benefit fee. Merchant property.
当前解决此问题的方案，主要是依靠商户自身从流程和监管上尽量避免问题的发生。一方面从流程上，例如设置专门的退货中心；另一方面从监管上，对操作员进行业务培训，完善商铺摄像头等；The current solution to this problem is mainly to rely on the merchants themselves to avoid problems as much as possible from the perspective of process and supervision. On the one hand, in terms of process, such as setting up a special return center; on the other hand, in terms of supervision, provide business training for operators, improve store cameras, etc.;
当前的方案主要还是依靠商户人工监管的方法，店主不可能一天24小时都盯着POS机，因此仍然存在安全隐患。The current solution mainly relies on the method of manual supervision by merchants. It is impossible for shopkeepers to stare at the POS machine 24 hours a day, so there are still potential safety hazards.
