You can use this application to write contacts on NFC tags. You can do this as a vCard or in a compression way, so you can store more contact information on the tag.
Write a business card The app provides 3 different use cases to write a business card:
1. Export contact Start your contact app and select a contact. Now go for this contact to the options and then to the sub-menu “share“. Choose the app “NFC Business Card“ in the popup. After the selection you will see the Export View, which is described below.
2. Use the write button of the app In the app “NFC business card“ you will find the button “Generate business cards“. By clicking on it you will see a selection of all of your contacts. Select a contact to move to the export view of the app.
3. Rewrite generated business cards More information can be found below.
The export view In each of the export possibilities you will reach the export view. There you have the possibility to analyze the contact details, edit them and exclude them from the data. A checkbox in each line describes, whether this data is to be exported or excluded. At the bottom of the view, you see a live calculation of the data size. This shows you the non- compressed and compressed size. Make sure that this size does not exceed that of your NFC tags. You can also add a fallback to the NFC tag. If the fallback option is enabled a participant without installed “NFC Business Card“ app will automatically be prompted to download the app at Google Play. This requires some additional bytes of memory. Once you have customized the contact data, you can write the card on one of the buttons either compressed or as a standardized vCard to a NFC tag. To do this, press one of the buttons and hold a NFC tag to your device, when the next window appears. You also can write on multiple NFC tags sequentially. The write operation is not terminated as soon as you confirm it by clicking the button.
Advantages and disadvantages of compressed writing As already mentioned, you have 2 options to write. With the compressed version you can write much more data on the business card. This is a great advantage if your NFC tags are smaller than the data size of the vCard. A disadvantages is, that the recipient of the business card will also need to install the app “NFC Business Card“. This is not necessary, if you export the data as a vCard.
Import business cards There are several possibilities to import a business card. You can do it by clicking on the menu item “import business card“ in the app. In the next window you have to put the tag to the device. That will automatically show up the import view. However, if you do not want to start the app before importing the data, you can also put a business card directly to your smartphone.
Manage generated business cards As mentioned in before, you can rewrite generated business cards. You can do this via the menu item “Manage business cards“. There you can also get an overview of the business cards you got, how often and on what day you wrote them. With a long press on one of the contacts, you can permanently remove it from the list. You also can reset the history by clicking on the button at the bottom of the view. To select a contact to write again on a business card, use a simple click on the history entry.
