Pre-requisites: Ensure your NFC tag is programmable. Tap Tag stores up to 144 Bytes, which is roughly 36 characters of text.
Tip: Consider using a free contact-card site like LinkTree. It provides a short link, directing users to a webpage with all your information, ensuring you don’t exceed the tag’s memory.

Where to Position Your Tap Tag on Smartphones:
iPhone: Best at the middle or bottom of the phone’s back. Avoid the top where the NFC reader is located.
Android: Typically, the NFC reader is in the center-back. Position the Tap Tag at the top or bottom. As designs vary, test before permanently attaching the tag.
