I'm giving you a couple of ways to store your card for later use. Here's how they work.

The simplest way is to Save your card's data. When you save a card, its information goes into your web browser's Local Storage. Local Storage is a lot like a cookie, but it allows for more data than a cookie would.

But, like cookies, Local Storage may expire a year or so from now, so you shouldn't consider it permanent. And your device or browser limits how much data I can put in its Local Storage: it can fill up! So for a really permanent record of your card it's better to Export it, and save the exported text so you can import it later.

But saving it is so much simpler, right? So you can do that, too.

The Save panel asks you to enter a name for the saved file, and then you can perform the save by clicking the button. Then that panel switches to the Load tab so you can see the result - which should be the Save Name with links to either load it or delete it.

If this fails, there are a couple of possibilities. You might have saved so many cards that your Local Storage is full; or you may have cookies disabled in your browser. Because even though Local Storage is not a cookie it's often controlled by the same browser setting that turns cookies on or off.

Next to the Save tab is the Load tab. You should have seen this panel already when you saved.

Under the Load tab is a list of all the card data you've saved, identified by the Save Names you chose; aren't you glad you wrote really descriptive ones? For each saved file there are links to load, or delete, it. Then at the bottom there's a link to delete every saved file you have.

Exporting your card is more permanent than saving it, so long as you don't lose the exported text; and you can also use an export to transfer a card design between devices, or to another person. Just remember that different web browsers render text differently. When your card is imported on another device the text may have shifted slightly, or appear a little wider or narrower than it did before.

The Export panel, at first, just shows you a couple of notes and has a great big button labeled Export your card data. Once you click that button your card design will be encoded as a large block of text, which will appear in the panel. This text is your export.

Make sure you select and copy this entire text. If it's incomplete, it may not be importable. Save the exported text in a text file, or email it to yourself, and it's been preserved.

The Import panel looks a lot like the Export panel did once you clicked the button. It looks like the picture on the right (although I've made it shorter in the picture).

All you do here is paste your exported text into the box and click the button. If your data is seriously mangled you'll get a warning; if it's slightly mangled, some of the settings for your card may be compromised. But usually you did a great job of saving that text, and so the exported card appears, as if by magic, on the page.

And that's all there is to that. But saving your card isn't the real reason you're here, is it? Because what you really want is to have that card in your wallet.

That's what we'll talk about in the next section.
