Creating an NFC tag that allows customers, friends, or even yourself to quickly check in to a venue on Foursquare is easy.
Before we can program the tag to initiate a check-in, we will need to get the venue ID for the venue we will want to check in to once the tag is scanned. To get the ID, visit the venue's Foursquare page from any browser. The ID is at the end of the URL. I have highlighted the ID in the URL above. You will need to take note of the ID, either by sending it to your device or keeping it close by to enter it when we get to that step.
Launch the NFC Task Launcher app on your Android device. Select Create Task and add a new action. From the list of actions, select Social Networking.
Under the Foursquare section, either paste the venue ID into the field, or type it in by hand. Once the ID is entered, press the + sign next to the box.
Confirm that the venue ID is correct under the pending tasks. If it is, select Write Tag.
I would suggest checking the box to lock the tag. By checking this box, you will prevent any unwanted reprogramming of the tag. Touch the tag to the back of your device to write the Foursquare venue information to the tag.
Going forward, anyone with an NFC-capable device (currently only Android is supported by the Foursquare app) and a Foursquare account can tap on the tag and will then be presented with the Foursquare check-in screen for the venue.
