I have been using a platinum login token since they were first issued 7 years ago. It has always worked great, easy to use, with a combination of numerical characters and the letters of the alphabet. The platinum token is about 13 times more secure compared to the replacement digital gold card+. Two weeks ago, IB sent me an email urgently instructing me to login to my account management and order the new replacement digital gold card+ as my platinum card had reached it's expected battery life, could fail at any time, and was being discontinued. So I did as instructed. When I received the new digital gold card+, I logged into my account with the platinum token and activated the new digital gold card+, logged out of my account, and tried to log back into my account to try out my new digital gold card+. I could not login into my account through the IB website. I tried to login to TWS and that worked; However, the account management link in TWS would not get me into my account management. I called IB customer service and reached a very pleasant login card assistant who tried to help solve the problem and did manage to fix the login through TWS but was not able to fix the account login through IB's website. He did not know the reason that was causing my login problem, but he was not going to provide me any further help because my firefox browser version was not version 23 or later. For two weeks now and counting I still can not login to account management through the IB website.
As for the digital gold card+, the card buttons work well if the card is laying on a flat table top. However, when I am holding the card in my hands, the buttons frequently activate from touching the back side of the card, frequently do not activate from the top side of the card if fingers are touching the back side of the card, and moving fingers across the back of the card can activate several unintended numbers in one login attempt. This new digital gold card+ is cheap ($20.00 hold on account compared to a $150.00 hold for the platinum card) and does not function reliably which the platinum card did. I hope others are having a much better experience with the use of their new digital gold card+. If you have a need to carry your login device in a billfold, like a credit card, the new digital cards will have that ability. The IB customer service rep that worked with me said I cannot go back to the platinum card even though it only needs 2 new coin cell batteries to extend it's live for many more years.
