These NFC cards are made by the same factory as Samsung and SONY's NFC tags.
You can program these NFC tags (free app from google play store) to do the following things by just swing your phone on the NFC tags:
- Place one tag next to your bed to enable silent mode or loud mode (it's a switch).
- Place one tag in your car to enable Bluetooth, turn the ringer/notification volume up to full.
- Place one tag on the front door of your house to enable/disable WiFi.
- Place one tag at work to turn WiFi off, put your phone in silent mode.

More on NFC:
NTAG213, NTAG215, and NTAG216 have been developed by NXP Semiconductors as standard NFC tag ICs to be used in mass market applications such as retail, gaming and consumer electronics, in combination with NFC devices or NFC compliant Proximity Coupling Devices.
NTAG213, NTAG215 and NTAG216 (from now on, generally called NTAG21x) are designed to fully comply with NFC Forum Type 2 Tag and ISO/IEC14443 Type A specifications.
Target applications include Out-of-Home and print media smart advertisement, SoLoMo applications, product authentication, NFC shelf labels, mobile companion tags.
Target use cases include Out-of-Home smart advertisement, product authentication, mobile companion tags, Bluetooth or Wi-Fi pairing, electronic shelf labels and business cards.
NTAG21x memory can also be segmented to implement multiple applications at the same time. Thanks to the high input capacitance, NTAG21x tag ICs are particularly tailored for applications requiring small footprints, without compromise on performance.
Small NFC tags can be more easily embedded into e.g. product labels or electronic devices. The mechanical and electrical specifications of NTAG21x are tailored to meet the requirements of inlay and tag manufacturers.
