What is the difference between the security token and the One Time Password (OTP)?

Security token: It’s a small electronic device (looks like a small calculator) that generates a one-time password which you will need to insert when you authorize your online transactions.

When and how to use it
A 7-digit number will display on your screen at the final stage of your payment. After switching on your token and entering your token PIN, type in the 7-digit number and click the button 'on'. A 6-digit response number with a lifetime of 30 seconds will appear on your security token. Please enter this number to authorize your transaction.

One Time Password (OTP): It’s a highly-secure automatically generated validation code, sent to your mobile phone, to authenticate you for a single transaction online.
