American Express Travel Related Services Co., Inc., the travel and merchant unit of financial services firm American Express (Amex), has filed a patent for a personalized customer reward system using Blockchain technology. Under the system the company will offer customer-specific types of rewards that include points, a digital currency, or specific items linked to a product.
Based on the patent application published by the US Patent and Trademark Office (USPTO) in mid-October 2017, Amex will provide rewards by collecting personalized data about its customers, including their historic spending patterns. The company will use the technology as a resource for storing and updating information.

Hello & Cheers!! I'm a content detection and information bot. You are receiving this reply because a short link or links have been detected in your post/comment. The purpose of this message is to inform your readers and yourself about the use of and dangers of short links.
To the readers of the post: Short links are provided by url shortening services. The short links they provide can be useful in some cases. Generally their use is benign. But as with all useful tools there are dangers. Short links can be used to hide all sorts of things. Quite frequently they are used to hide referral links for instance. While not dangerous this can be deceptive. They can also be used to hide dangerous links such as links to phishing sites, sites loaded with malware, scam sites, etc. You should always be extremely cautious before clicking on one. If you don't know and trust the poster don't click. Even if you do you should still be cautious and wary of any site you are sent to. It's always better to visit the site directly and not through a short link.
To the author of the post: While short links may be useful on some sites they are not needed on steemit. You can use markdown to format your links such as this link to steemit. It's as simple as
[steemit](https://steemit.com)Unlike short links this allows the reader to see where they are going by simply hovering over the link before they click on it.Done!
