Chip Integration


Embedding and Applications

HaLo chips can be embedded in a variety of materials including plastic, fabric, epoxy, wood and glass.

Typically we recommend that a HaLo be embedded no deeper than 1mm in another material, however, it's always critical to test embed several HaLos prior to mass production to ensure that readability is not compromised.


HaLo chips cannot be embedded under or on metal. This includes foils and metallic threads in textiles. An insulator like thick double sided tape, plastic or epoxy can sometimes be used to affix a HaLo to metal.

Bulk Scanning

Web App

In order to enroll a large number of HaLos at once, we have created a simple, open source browser-based scanning app (opens in a new tab) that allows one to quickly capture chip information.

Bulk Scan

This app is hosted at bulk.vrfy.ch (opens in a new tab) and can capture chip information to a browser's local storage which is persistent across page refreshes. Once all the desired chip information has been captured, it can be downloaded to the phone as a JSON-formatted file.


Leveraging LibHaLo (opens in a new tab), bulk scanning can easily be scripted with a hardwired NFC scanner and desktop computer. See the LibHaLo CLI Documentation (opens in a new tab) for more information. Most off the shelf NFC readers are compatible with LibHaLo CLI.


For high volume production, we can provide custom solutions for automated scanning and ERS (opens in a new tab) enrollment.


For textiles and garments, creators have used a variety of means to embed HaLo chips including:

Embroidered patches or soft tags sewn or adhered above chips
Silocone patches sewn around chips
Sewn into the corner of an existing pocket
Stitched between two layers of a garment on a sleeve

Other Materials

HaLo chips can be embedded in wood, vinyl, glass and other materials if placed near the surface and away from metal:

Pressed within a vinyl record
Under a wood inlay
Ahered to glass using a specialized epoxy
