onetouchlabel 4+

Onetouchlabels are programmable NFC chips. The initial programming is easy and can be carried out without the use of an app. Thanks to the onetouchlabel app, all subsequent changes and reprogramming is just as simple.

To reprogram a onetouchlabel, simply open the app and then touch the NFC chip with the right upper corner of your iPhone. Simple, easy-to-follow instructions will then appear on your screen, leading you through the process. All you need is to be sure you have the security code that came with your onetouchlabel. Without it there is no way to change anything on the chip.
