Make sure the amount of your purchase is right and deduct that amount from your checkbook so no checks bounce. Sign Your Card as soon as you receive it. Protect Your Card from damage such as excessive heat or magnetic objects which could deactivate it. Play It Close. Know the Limits.
Many issuers limit daily purchases and withdrawals.
That's good security but could leave you short if you're away and exceed that limit. MasterCard International Incorporated. All rights reserved.
