We are reissuing Calder debit cards with contactless technology. Cards are being replaced as they expire, so you will receive yours in the month your current card is set to expire. There is no charge and you do not need to do anything to request one.
Not in any practical sense. The card has to be within about two inches of a reader, and the number transmitted is a one-time code rather than the card number printed on the front, so it cannot be reused. Card sleeves are unnecessary and we do not sell them.
Not for most purchases. Above certain amounts, which the merchant and the network set, the terminal will ask for a PIN or a signature.
Your previous card stops working on the last day of its expiration month. Destroy it by cutting through the chip, and remember to update any recurring payment that draws on the old number.
