Barclays takes customer security very seriously and has implemented several measures to protect customers' data and prevent fraudulent transactions at its ATMs. Some of the security protocols and procedures followed by Barclays ATMs in Norwich include: 1. PIN protection: Customers are required to enter their Personal Identification Number (PIN) using a secure keypad that conceals the entered digits from anyone standing nearby. The ATM also has an automatic time-out feature, which requires customers to re-enter their PIN after a certain period of inactivity. 2. Card reader: Barclays ATMs use a card reader that authenticates the customer's card by reading the magnetic strip or chip on the card. This helps prevent fraudulent transactions using counterfeit cards. 3. Transaction limits: Barclays has set transaction limits for its customers to help prevent fraud. These limits vary depending on the type of account and the customer's history with the bank. 4. Surveillance cameras: Barclays ATMs are equipped with surveillance cameras that record activity at the machine. This helps to deter criminal behavior and provides evidence in case of a security incident. 5. Regular maintenance: Barclays conducts regular maintenance checks on its ATMs to ensure they are functioning correctly and have not been tampered with. This includes checking for any signs of tampering or damage that could compromise the security of the machine. 6. Employee training: Barclays employees who work at ATM locations receive regular training on security protocols and procedures. This ensures they can identify potential threats and take appropriate action to protect customers' data and prevent fraudulent transactions.
