Programmable NFC Tags in India

A programmable NFC tag is a blank NFC chip that ships un-encoded so you write its data yourself — a URL, contact card, Wi-Fi login, or other short record — using any standard NFC writer app on a compatible phone. It stays rewritable, so the stored link can be changed again later without replacing the physical tag.

Yes. LINQS NFC stickers and cards ship blank and un-encoded. Use a dedicated NFC writing app on iPhone or Android to write supported NDEF records. Apple Shortcuts can use a tag identifier to trigger an automation, but Shortcuts does not write the tag contents.

Use a dedicated NFC writing app on iPhone or Android. Apple Shortcuts can run an automation when a saved NFC tag identifier is scanned, but it ignores the tag contents and does not write the tag.

These are NXP chip models that differ by memory capacity. NTAG213 stores 144 bytes — enough for most short URLs and review links. NTAG215 stores 504 bytes, suitable for vCards and richer records. NTAG216 stores 888 bytes, the maximum in the NTAG21x family. Start with NTAG213 unless you know you need more memory.

Standard LINQS NFC tags are rewritable — you can overwrite the stored data as many times as needed. Locked tags (write-protected after encoding) are available on request for deployment scenarios where the URL should not be changed.

By default, all tags ship blank so you can encode them yourself. If you need tags pre-encoded with a specific URL or NDEF record in bulk, request it through the bulk quote flow and LINQS will encode before dispatch.

Scan range depends on the reader antenna, not the encoded content. Standard NTAG213/215/216 stickers typically scan at 1–4 cm. Anti-metal tags use a ferrite backing that restores range on steel and aluminium surfaces.
