The Acekard 2i anti-counterfeit code was established as a means to verify the originality of the product. The code was a direct response to a market flood of 1:1 clones. Officially, Acekard has stated that the clones are made of "cheaper parts", however, this claim has not been substantiated. Therefor the main use of the anti-counterfeit code would be in direct relation with the 1 yr warranty Acekard offers on all of their products.

Anti-counterfeit Code Location

The unique 20 digit anti-counterfeit code is located behind the holographic Acekard logo sticker, placed on the back of AK2i units. The top sticker must be pealed back to reveal the unique 20 digit number. The numbers are presented in 10 digit blocks, stacked 5 over 5, with a space separating the two 10 digit blocks.

Known Issues

The code itself is printed on a sticker placed under the holographic Acekard logo sticker. Some users have reported that the anti-counterfeit code sticker peals away with the top layer, forcing users to read the code backwards. Thankfully the code is printed on a see-through clear backing making this task possible.

Often times 1 or more digits of the code are poorly printed forcing the user to guess the full code. Each digit is a number between 0 and 9 making this task possible as well.

Using the Code

To verify the authenticity of the AK2i the code must be entered into the Acekard Website. The code should be entered from top to bottom, left to right, and without spaces. The top left 5 digits should be entered first, the top right 5 digits entered second, the bottom left 5 digits entered third, and finally the bottom right 5 digits. Once this is complete the user can verify the code by pressing "enter" on their keyboard or by clicking the provided "check" button.

Possible Results

A legitimate code which has been entered correctely will result in the following message:

"This Anti-Counterfeit code is correct! You bought a REAL Acekard! If this code shows had been checked already but it's your first time to check then you maybe bought a fake card. Please contact your vendor for refund."

A legitimate code which has been checked more than once will result in a similiar message:

"This Anti-Counterfeit is correct and had been checked 2 times already. If this code shows had been checked already but it's your first time to check then you maybe bought a fake card. Please contact your vendor for refund."

Additionally, the Website will attempt to provide the last 10 times the code has been checked with dates and IP addresses.

An incorrectly typed code or a fake code will result in the following message:

"Sorry, the Anti-Counterfeit code is not exsit! You bought a FAKE Acekard!"

Interpreting the Code

Each code is unique, and Acekard has assured the public that there is little chance that they will run out of codes anytime soon. When the code is checked, if anything other than "You bought a REAL Acekard" is displayed, you probably have a fake/clone AK2i. This, of course, is assuming that you were the first to peal off the sticker. It is possible that a reseller may check the code or that a second-hand card's code has already been checked. Before you panic consider the uniqueness of your situation. If the card was purchased new, you were the first to remove the sticker, yet the Website displays a checked number greater than 1, then your card is 100% a clone AK2i.

Current reports state that the 1:1 clone continues to function the same as the legitimate AK2i. There have been reports of full AKAIO functionality and the ability to update the bootloader. It is still rather early in the life of these clones and the end-users do not yet know what problems they may cause. If you do end up getting a clone, consider contacting your reseller and asking for the card you paid for.
