Every Friday, Lynda Steele dips into the viewer mailbag to answer your questions. This week, Steele on Your Side looks at deactivating contactless credit cards and anti-spam legislation.

Deactivating contactless credit cards

Steve wrote us after requesting to have the contactless PayWave chip in his TD credit card deactivated. He says the bank told him it couldn't do that and he wants to know why.

TD Bank says it does not have the ability to disable this technology because contactless capability is an embedded part of the chip and PIN technology.

TD says the level of security is high with the cards and it uses powerful encryption measures for added protection.

Customers are also protected by the "zero liability policy", which states a cardholder does not have to pay for any fraudulent transactions that may occur with your account.

Anti-spam legislation

Stewart wrote us about the new anti-spam legislation that went into effect on July 1st. He says he's still receiving a lot of spam email and he wants to know why.

After July 1st, any new contacts cannot be made without your consent. But the full legislation doesn't kick in until July 1, 2017.

That means if you had a previous business relationship with a company, they can still email you for the next 36 months. This is called "implied consent". You can still get off those email lists by unsubscribing.

But many businesses are taking advantage of this transitional time to get "express consent" from their clients. In that case, express consent does not expire.
