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。尤其是老年人成为信用卡诈骗的牺牲品，针对老年人的金融犯罪有很大一部分是由亲属或照顾者实施的，其中大部分涉及支付卡。65岁以上的人中有很大一部分人把他们的个人识别码给了别人，或者用卡写了下来。目前的芯片或基于卡的支付系统无法防止这种欺诈，尤其是让老年人面临经济困难。SwIDch的智能卡在大小、形状和功能上将与普通支付卡相似。然而，它的嵌入式纳米光电指纹传感器激活了一个运行OTAC算法的集成微芯片，该算法为每次使用创建一组新的凭据(卡号/CVC/有效期)。智能卡可以像传统卡一样用于非接触式或终端支付-唯一的区别是，在每次交易之前，指纹扫描都会创建凭据。对于银行端的支付处理，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.
