By sending an SMS containing a code to a user’s mobile number you can verify an association between the user and the mobile number. This can be used to:
- confirm a user’s mobile number
- verify a user’s attempt to login
- authenticate a transaction
HSL Mobile is offering a new verification code service that is free to low volume users during the service’s BETA phase. This service is being offered to promote the use of SMS for verification codes, allow developers to experiment with the use of verification codes in their projects and for other interested parties to trial their use.
