The video shows the Cardslide Oslo. This is just cosmetically different to the Cardslide Copenhagen as for sale here. See the still images for the Cardslide Paris.
The Secrid card protector is unique. It will hold up to five credit cards (or cards the size of credit cards) nestle in a secure aluminium card protector, safe from unauthorised scanning, since no electromagnetic radiation can penetrate the casing. This is known as protection from RFID (Radio Frequency Identification). RFID scanners can read the chip in an ordinary purse or wallet without the owner being aware.
Crank a small lever and the cards are pushed out in a fan for the selection by the owner. How many times do you have to dig out a credit card, library card, transport card, ID card? All day long, it seems. Pull out your Secrid wallet, crank the lever, select the card from the aluminium card protector, use it, slip it back in and the wallet goes back into the pocket or purse.
They work so well. Buy one and you will have it for life.
