web coupon

This is a assignment to capture our customers' email addresses or else cell phone numbers by offering a discount coupon.

Job description-

a) Ask the user to choose either email or SMS.

b) If the choice is email the application sends an email request from the user's phone to our business email asking for the discount coupon. By taking the user send us an email from his/her phone there is no chance that he/she has given us a bogus address or misspelled it.

c) If the choice is SMS the application sends an SMS message from the user's phone to our business phone querying for the coupon.

d) After effectively completing either of the steps above the application displays the coupon on his/her phone. The user then displays the coupon on the phone to our employee as well as the employee rings up the discount price. This last step is what we are missing.
