- Figure 1A shows a system 10 suitable for modifying a object 15 and in particular altering a portion thereof which may be considered as a substrate by forming a 2D code 17 such that the code is part of the object 15.
- An energy or projectile source 18 ca be used to direct a electromagnetic radiation towards the object 15.
- the source .1 is a laser, electron beam, particle emitter, lamp, light source and a patterned mask, a heat source, or other con trollable source of electromagnetic radiation or projectiles.
- a beam 20 of particles or radiation is directed to a particular volume of the object 15 such that a 2D code 17 can be written or formed.
- the beam 20 can be moved using a movable controller or head.
- the object 15 can be translated in space while the beam remains stationary, in one embodiment, a pulsed laser can be used as the laser source 18.
- the laser is a pulsed d:YAG laser.
- the laser modifies a dopant contained in the material that forms the object, thereby changing the optical propertie of the material where the code is written or formed. Suitable dopants include, by way of non-limiting example, alkali metal, nanocrysta!s. and semiconductor dopants.
- the beam impinges or other chemical bond breaking phenomena or structural defect changing device is applied to a predetermined area of the object such that a code can be written.
- Specific coordinates for determining the spatial movement of the object or the program for scanning the beam can be entered using a computer 22 or controller.

- a beam director 28 such as a lens can be used to focus the laser beam 20 at various positions wit hin the selected region of the object 15 to receive the 2D code. Since the beam director allows the code writing to occur I mm, 2 mm or any other distance in which the beam contacts the substrate which constitutes the object, it is clear that the object (e.g., a bottle or syringe) would need to be destroyed or damaged to try and remove or extract the code by a counterfeiter.
- FIG. IB a hand held scanner 27 is shown reading the code 17 which has been formed in the object 15 in the presence of a code illuminating light source 30 such as UV, IR, or other source.

- the source 30 is turned on, the code .17 appears and be scanned, read, photographed, or otherwise captured for decoding.
- a hand held scanner 27 may be practicable. However, if a consumer, seller, distributor, law enforcement agency or other interested party wants to authenticate the object, using a mobile device 29, such as a smart phone with a camera, can take the place of a hand, held scanner. QR codes are used for various purposes and are amenable to eticoded data of interest relative to the object. This data can include source information, expiration dates, an. updated log of transport and storage locations, and other information of interest. Thus, a mobile device 29 can capture codes in t e field and allow for authentication and tracking of objects around the world.
