Home alert with location information

This ginstr app allows sending an alert by simply scanning an NFC tag with any NFC capable smartphone. The alert can be distributed to an unlimited number of SMS and e-mail recipients.

The NFC tag is fix mounted to a wall, or any other fixed area. When the NFC tag is scanned the location of its position is transmitted as part of the alert details information you will see in the ginstr platform. This app does not require GPS to be switched on;therefore it is very useful because the smartphone battery will not be drained by GPS.

If the NFC tag is carried around by the resident (e.g. with an NFC wristband, NFC ring, NFC necklace etc.) when creating an alert the GPS position of the resident will be sent to the security centre along with other detailed alert information.

The alert SMS (text messages) and alert e-mails include relevant and important alert information including a link to a map that pinpoints the location where the alert was generated. This allows the rescue team to immediately see where the alert came from so they don´t lose any time in finding the person.

Each alert is transmitted into the secure ginstr cloud for documentation. The alert handling is processed and managed by the ginstr backend.

NFC tags

  • NFC tag number
  • Assignment to a resident
  • Real address where the tag is currently mounted
  • Multi-line comment

Phone number per smartphone
Phone number of the smartphone cannot be retrieved programmatically from the SIM card or phone because this information is not stored inside the mobile device.
It is important to be able to call a resident after an emergency alert is triggered from the mobile phone. The phone number of each mobile device is stored in this table:

  • Serial number of the mobile device
  • Assignment of the mobile device to a resident
  • Phone number of the mobile device
  • Multi-line comments


  • User name
  • First name
  • Last name
  • Customer no.
  • Land-line telephone number of the resident
  • Multi-line comment regarding the resident
  • All e-mail addresses of the recipients of this alert
  • All SMS numbers of the recipients of this alert
  • Real address where the tag is currently mounted
  • Multi-line comment regarding the NFC tag
  • Phone number of the phone that was used for sending the alert
  • GPS location at the moment of the creation of the alert
  • Address related to the GPS location that was retrieved at the moment of the creation of the alert
    (this allows for ex. to find out if an NFC tag is still mounted at the location where it is supposed to be mounted)
  • Time stamp of the alert
