The video shows the silver card protector. This is the same in all respects except for the colour. See pics for details.
The Secrid card protector is unique. Up to five credit cards (or cards the size of credit cards) nestle in a secure aluminium casing, 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 Card Protector, crank the lever, select the card, use it, slip it back and put the Card Protector goes back into the pocket or purse.
They work so well. Buy one and you will have it for life.
