Card Protection

Tools and materials to ensure quality and protection for cards

An important aspect of our certification services (Authentication, Standard and Digital), is represented by the tools and materials we have adopted to guarantee our customers maximum quality and protection for their cards.

Polycarbonate case

Our protective cases are made of plastic polycarbonate and are ultrasound welded to ensure an absolutely safe sealing system: there is no way the card / sticker is going to be damaged in the process.
Our cases are:

  • ultrasound welded (it does not ruin the card)
  • Waterproof
  • anti-UV 
  • anti tampering (they break if you try to open them)
  • scratchproof
  • dustproof
  • highly transparent

The case, once welded, guarantees resistance to bumps and scratches and allows transport without ruining the card. It also matches the card with its personal certificate so that replacement is not possible: in the event of tampering, the case is destroyed irreparably since the ultrasound welding guarantees that the two halves of the case are welded without gaps in the plastic material. The two halves are literally melted together, so it is impossible to "reopen" the welding to replace the card inside without damaging the case.

Ultrasound welding of the case

In the final phases of our grading process the two halves of the plastic polycarbonate case are welded with an ultrasound generator and an actuator equipped with a sonotrode, ie the component that transmits the vibration located on a surface.

To weld the two halves we use a process that creates a progressive intermolecular clutch between the two sections which leads to a localized increase in temperature concentrated in an extremely short interval of time (in the range of tenths of a second) and causes the fusion of the junction area.

The two fused micro-surfaces penetrate one another and weld without the need for glue or additives. We this method we are able to obtain the maximum precision and cleanliness because only the specific junction area is involved in the process. The fusion is well-defined and precise and prevents any type of damage, even microscopic, to the card inside. Furthermore, this system prevents any tampering of the case, since it's basically impossible to open it without irreparably damaging the case.

Anti-fraud holographic stamp

On the back of our paper certificate you will find the exclusive GRAAD holographic stamp that certifies without doubts that the label inside the case is indeed authentic. If you notice that the stamp is not present or not genuine, you may have run into a counterfeiting attempt.

Our holographic stamp cannot be counterfeited because it is made with a unique and unmistakable matrix. If you have any doubts, check that the stamp matches our official description. If you can't ascertain the authenticity of the stamp, we suggest to take a close-up picture of it and send it to our customer service.


Our certification of authenticity and grading is anti-fraud and anti-counterfeit because the collector interested in buying has different safeguards and methods of verification to make sure that the card contained in the case is genuine. GR.A.AD guarantees with absolute certainty the authenticity of a card because:

  • the case is sealed by ultrasound welding which makes impossible any tampering attempt without damaging the case. It is thus impossible to replace the card inside with something else (a fake card or a card in worse overall conditions)
  • the eight-digit code on the certificate is unique
  • if, during verification, you enter a code that does not exist (because someone has tried to counterfeit it) the system will show a warning message that suggests you to check that you have entered the number correctly.
  • if you insert the same code three times, and for three time you receive the same warning message, you have probably run into a counterfeited card, ie not authenticated by GRAAD and therefore not certified.
