Swidch SmartCard: a secure fingerprint IoT payment card for the elderly with patented OTAC™ technology.

2018年，近9%的英国人口成为金融犯罪的受害者。特别是老年人成为信用卡欺诈的受害者，其中很大一部分针对老年人的金融犯罪是由亲属或护理人员实施的，其中大多数涉及支付卡。很大一部分65岁以上的人将他们的PIN交给了其他人或将其写在卡上。目前的芯片或基于卡的支付系统不能保护这种欺诈行为，特别是使老年人面临经济困难。SwIDch的智能卡在大小，形状和功能上与普通支付卡一样。然而，它的嵌入式纳米光电指纹传感器激活一个集成的微芯片运行OTAC算法，创建一组新的凭证（卡号/CVC/到期日）为每次使用。智能卡可以像传统的卡用于非接触式或终端支付-唯一的区别是，在每次交易之前，指纹扫描创建凭证。对于银行方面的支付处理，交易的处理类似于一次性虚拟卡，但客户不需要智能手机，更不用说互联网连接了。

Nearly 9% of the UK population have been victims to financial crime in 2018\. Especially the elderly fall prey to card fraud whereby a large share of financial crime against the elderly is carried out by relatives or carers and a majority of that involves payment cards. A large share of those over 65 give their PIN to someone else or have it written down with their card. The current chippn or card-based payment systems cannot protect from this kind of fraud and especially exposes the elderly to financial hardship.SwIDch's SmartCard will be just like a regular payment card in size, shape, and functionality. However, its embedded nano-optoelectrical fingerprint sensor activates an integrated microchip running the OTAC algorithm which creates a new set of credentials(card number/CVC/expiry date) for every use.The SmartCard can be used like a conventional card for contactless or terminal payments---with the only difference that before every transaction the fingerprint scan creates the credentials. For the payment processing on the bank's side the transaction gets processed similarly to that of a disposable virtual card, however the customer does not need a smartphone let alone internet connection.
