What is a Tamper Evident Security NFC Sticker?
Tamper evident security Near Field Communication (NFC) stickers are NFC tags designed to become unreadable when removed or tampered with. They are used to confirm the integrity of sealed packaging or assets. There are two types: tamper loop NFC stickers, which disable when their extended antenna loop is broken, and fragile NFC stickers made of brittle materials that fracture during removal, breaking the antenna when peeled. Both types use permanent adhesive but are engineered for destructive removal, unlike general NFC stickers, which can often be removed intact without disabling the NFC chip.
Tamper evident NFC stickers are used for anti-counterfeiting applications on wine bottles, pharmaceutical containers, luxury goods packaging, and high-value product authentication requiring integrity verification. These NFC stickers serve as physical integrity certificates and authenticity verification seals for products requiring tamper detection.
How to Choose a Tamper Evident Security NFC Sticker
- Tamper Type: Tamper loop NFC stickers break antenna continuity when removed and are best for curved closures like bottle necks. Fragile NFC stickers tear apart upon removal attempts and are suitable for flat surfaces.
- Shape and Size: Only a few common sizes are listed; other options may be available by special order depending on mold availability.
- Availability: Limited stock is kept for sampling. Bulk orders are typically custom with longer lead times and higher minimum order quantities (MOQs). Lower unit pricing is available at higher volumes.
- NFC Chip Type: NXP NTAG 424 DNA NFC tamper tags (TTs) enable cryptographic authentication. NTAG213 TTs offer lower-cost tamper detection. The TT chips include tamper input functionality. Standard NTAG213 is used in non-secure, fragile NFC stickers.
Customizing a Tamper Evident Security NFC Sticker
- Printing Options: Tamper loop NFC stickers can be printed with black thermal transfer text or IDs. Fragile NFC stickers may support color inkjet printing on white backgrounds but are not specifically designed for in-house inkjet use.
- Special Orders: Both types can be custom ordered with full-bleed color printing. Other shapes, sizes, and materials may also be available depending on mold and material inventory.
- Encoding: GoToTags can encode NFC tags during production, or customers can encode later using the GoToTags Desktop App.
Recommendations
- Use tamper evident NFC stickers only when physical tampering detection is essential for security, as standard NFC stickers provide better cost-effectiveness and availability for basic authentication applications.
- Do not use on reusable or repositionable surfaces.
- Confirm compatibility with surface and product type before ordering.
- Contact GoToTags to verify available shapes and materials, as mold inventory changes.
