Questions are welcome! These are 600 yen each, but I welcome bulk purchases, considering packaging and shipping. One for 600 yen, two for 800 yen, three for 1000 yen, and five for 1200 yen! Product Description: These tags allow you to instantly access a store link or review site by simply holding your smartphone over them. You can also set up Wi-Fi passwords, allowing you to connect to Wi-Fi with a tap. They are very convenient to place near a cash register, as they are easier to read than QR codes. NFC tags can be used with any NFC-compatible device. Compatible iPhone models are iPhone 7 and later. Android phones are also compatible with about 90% of smartphones. You can check compatibility by searching for your model name + NFC. A separate app (NFC Tools) is required for setup. NFC Tools is available for both Android and iPhone. Important Notes: There is a possibility that some models may not be able to read the tags. These are not GPS tags. These are not memory cards, but I didn't know the correct category, so I put them in the memory category.
