ATMCardvs.CheckCard

Asanalternativetowritingchecksandusingacreditcard,mostmajorbankshaveteamedupwithmajorcredit-cardcompaniestoissuecheckcards.

CheckcardsaredifferentfromstraightATMcardsinacoupleofways.First,checkcardsarealsoknownasdebitcardsbecauseofhowtheywork--insteadofgettingcreditforyourpurchaseandreceivingamonthlybill,likeyoudowithacreditcard,acheck/debitcarddeductsmoneyfromyourcheckingorsavingsaccount.

Also,whileyoucanonlyuseyourATMcardattheATMmachine(andsomegrocerystores),youcanuseacheckcardatmostretailersthatacceptcreditcards.

Thereareexceptions.Somehotelsandrentalcarservicesonlyacceptcreditcardsbecauseit'seasier,cheaper,andlessofarisktothemthancheckcards.Thosethatdoacceptcheckcardsoftenputacertainamountofmoneyinyourbankaccount"onhold"(unavailabletoyou)-usuallythecostoftheroomorrentalincludingtaxesandotherfees,plusapercentageofthetotalorafeetocoverpossibledamages.Whenyoucheckoutofthehotelorturninyourrentalcar,thedifferencebetweenthe"hold"amountandwhatyou'reactuallybilled.isreleasedbackintoyouraccount:Thisissomethingtoconsiderwhenusingyourdebitcardtoreserveahotelroomorrentacar.
