The Capital One skill allows you to check your credit card balance or make a payment when one is due. This is secure: The skill performs security checks and requires you sign in using your username and password. Then, when you open the skill, you must provide a four-digit code to confirm your identity. Just be wary of who is around when using the skill -- anyone who overhears you say your personal key can access your banking or credit card info just by asking Alexa.
Because Amazon opened up the development of Alexa Skills to anyone with the free Alexa Skills Kit (ASK) in 2015, anyone can create an Alexa Skill. As Alexa uses Natural Language Programing (NLP), those looking to build a skill don't need to worry about complex speech recognition. The ASK tools also makes it easier for novices to work with sophisticated NLP ideas.
You can create a flash briefing skill if you own, or have the right to distribute, original text or audio content that updates frequently. You should understand web technologies and have the ability to configure HTTPS, RSS and/or JSON content. The voice interactions for a flash briefing skill are defined by Amazon, but you must be able edit the format of your content so that the flash briefing Skill API can understand it.
The first of the Alexa flash briefing options to include is an error message. Alexa will read this to your audience if your briefing is unavailable. Next, you’ll be asked to paste the RSS feed provided by your audio host. The “preamble” field is a short, introductory cue that Alexa will read before delivering your briefing. Finally, fill out any remaining Alexa flash briefing options — frequency, briefing name, category/genre and more — and soon you’ll be ready to launch.
