This is just one of the many compromises that allow CARD.PM to claim to be universal.

There's a difference in appreciation between the worlds of Unix (Android, iOS, OSX) and Microsoft which means that, to this day, vCards generated from your mobiles will give an unsightly "À£" when opened on a PC if they contain accents.

We have chosen to remove accents from all cards until this situation is resolved, in order to guarantee clear legibility; and we are actively campaigning - among many companies - for a clear standard on this point.

Of course, we store your details in the correct format, and will convert all vCards as soon as the expected change in standard is fully implemented.

This is an Apple security feature which is beyond our control, which is not a bug in our service either, and which breaks the link (the URL) on the card for security reasons if you have never exchanged text messages with someone. This protection is designed to prevent fraudulent urls.

The only known solution to date is to send a message back to the sender of the text message.

That's why we've configured the default sms message as follows:

Hello, here is the interactive business card of xxxxxxxx - COMPANY (if the link does not open, please reply to this SMS) https://card.pm/xxxxxxx

In fact, if your contact sends you an SMS back (e.g. "thank you"), this will activate the card link.

Opengraph is an enhancement designed to be visible on compatible terminals.

Each map link corresponds to an OpenGraph tag under a standard that we respect, but each tool has its own policy concerning it. Some SMS software asks you to validate an option, while others only display it on Wifi, and ask you to click to load the image on the mobile network (to reduce data consumption).

Others only display them when your contact is already in the phone, to combat spam.

Finally, some phones or versions of phone OS are simply not compatible with OpenGraph and therefore do not display the tag or thumbnail in the SMS.

What is OpenGraph : OpenGraph was launched by Facebook in 2010 but is now owned by the Open Web Foundation. The aim was to allow easier integration between Facebook and other sites by displaying rich graph objects with the same functionality as Facebook objects. This allowed a degree of control over the information that was shared.

The platforms of the main social networks now offer this tag, although Twitter has developed its own for Twitter Cards (but still accepts the Open Graph if necessary). The information is sent via OpenGraph meta tags in the code section of your site.

Although we make every effort not to appear on our customers' cards (which is already the case) and to offer a white-label service, traces of the name of our service remain because we host all our customers' cards.

In fact, we appear in the map's URL (link), which is no more and no less than a web page (WebApp), as well as in the thumbnail generated by certain phones compatible with the Open Graph protocol.

Definition of the Open Graph protocol :

The Open Graph protocol is a set of tags that allows a webmaster to give the main social networks (Facebook, Google +, Twitter, Linked in...) precise information about its pages. This information will enable the social networks to better display a link on one of these pages that has been placed by their users.

The Open Graph protocol was originally created by Facebook and is now managed by the Open Web Foundation.

您可能会发现，在 iOS 13 之前，使用旧 iPhone 的联系人无法将您的 vcard (.vcf) 保存到他们的 iPhone 中。

这意味着当他们开始下载你的卡片时，他们的 iPhone 在点击 "保存 "后不会在通讯录中打开卡片，而是在 "文件 "中打开。

而 iPhone 应建议在 "通讯录 "中打开 Vcard。

如果你的联系人遇到这个问题，只是因为他们删除了 iPhone 中的 "通讯录 "应用程序，因此必须重新下载。

为此，他们需要到 App Store 搜索 "通讯录 "应用程序（此处直接链接 从 iPhone），下载并打开它。

剩下的工作就是再次下载 Vcard。

两种情况：

1 / 如果 iPhone 仍然提示在 "文件 "中打开，请转到 "选项"，然后查找 "复制到通讯录"，这时 Vcard 就会打开，你只需点击 "保存 "即可。

2 / 如果 iPhone 直接建议在 "通讯录 "中打开，那么点击它，一旦 Vcard 打开，点击 "保存"。

你可以在电话簿中按姓名或公司名称搜索，看看能否找到联系人的 Vcard。

If you receive the link to your map from the Gmail application on an iPhone, clicking on the link to open the map will open a lightweight Safari that will not offer you the option of creating a shortcut on your iPhone desktop.

You then need to 'copy' the link received in your Gmail application by pressing and holding on the link, then open the Safari application and 'paste' the link to your card in the Safari address bar.

Finally, you need to follow the standard procedure for creating a shortcut from an iPhone, which you can find in our helpdesk.
