The visual control is an easy, rapid and reliable way to authenticate a certified document or product.
The number printed next to the Bubble Tag™ gives access to the image of the Bubble Tag™ already stored in a database for a unitary visual comparison. This checking method, accessible via a PC, a PDA or a mobile phone with an internet connection, is extremely easy. More than 99.5% of people who tested it were able to carry out a visual comparison in less than 5 seconds.
The image of the Bubble Tag™ can also be printed on a document or in a register, in order to carry out a visual check without an Internet connection.
Advice
To carry out a rapid comparison, you don't have to take all bubbles into account. In fact, it is easier to compare similarities rather than differences. To do so, you single out a unique characteristic of the Bubble Tag™ and look for it on its recorded image. Look for an isolated bubble or a group of bubbles.
Access to the visual checking method has also been simplified for iPhone users.
