Store listing

Full description
The NFC TagWriter by NXP stores contacts, bookmarks, geo location, Bluetooth Handover, SMS, Mail, text messages and many more to any NFC-enabled tags as well as to items like posters, business cards, watches and many more containing NFC-enabled electronics. Once data has been stored the application allows also reading and viewing the programmed data including options to launch applications automatically based on the contained data. NOTE: Installing TagWriter on a non-NFC enabled phone is enabled now but it does of course not allow you to actually program tags. Anyhow, you can now prepare NFC data sets e.g. on a large screen device and then share them with an NFC enabled handset to actually make use of them. Besides that you can catch a pre-view on what you could do with a handset supporting NFC. Please contact us at [email protected] if you have problems. We will continue our efforts to add new features for your benefits and we work hard to provide a feature rich application ahead of other apps available in the market.

This includes a whole range of NXP and third party NFC-enabled contactless IC products like MIFARE Ultralight, MIFARE Classic, MIFARE DESFire, NTAG 21x, NTAG I2C, ICODE SLI & many others.TagWriter supports any NDEF pre-formatted tags for all NDEF operations but formating to NDEF feature is limited only to NXP Tags. Please help us to improve and provide “crash report” and/or contact us via [email protected]. This helps us to detect, analyze and provide fix for the ICs that have not been verified to work and so may cause problems or unexpected behavior on use.
