Multifunctional Smart NFC Ring Fashion

Overview:
The smart ring is a fashionable and wearable electronic product that includes four major features: NFC, M1 Card, ID Card, and Health Module. 
① With a set of built-in NDEF protocol standards for high-speed NFC chips, it's possible to connect a smartphone to complete function performance and data sharing; that way, many playful and convenient functions will be accessible. Place the smart ring within the NFC area of a smartphone to perform screen unlocking, app locking, quick app launching, name card and URL information sending and reading, etc. 
With a set of built-in 13.56 MHz high-frequency IC (integrated circuit) chips, the device can be used to copy most non-contact IC cards, such as access cards, elevator cards, parking cards, membership cards, and consumption cards. 
③With a set of built-in 125 kHz low-frequency ID chips, it can be used to copy all non-contact ID cards of the same frequency into the various cards above, too. 
④ On the inner side of the metal ring embryo, there are three items that are beneficial for your health:

How to use:
1. First, check if your smartphone has an NFC function. It can usually be found in the system settings. If no relevant options are found, contact the manufacturer's post-sale support, or search on Google if the smartphone model has an NFC function and confirm its NFC area. 
2. If your smartphone has an NFC function, turn on the NFC switch and search your app store for the software that applies NFC, then download and install it. 
3. Start the NFC app and perform actions according to the instructions.
4. Since NFC is a near-field communication technology, make sure to place the top side of the ring chip right close to the NFC area when reading any data to avoid failure in reading and writing. 
5. The NFC function will be based on this app, JACKOM. Please search on this link to download: ins.jakcom.com. (Or you can search for other NFC apps that are based on NFC devices.)
