D2, Task 4, Unit 14

P7: "To send contact information from your phone (Info like your mobile number) to another phone, first you go into your phone's settings and find something like my profile, my number or this phone. Or you could get the number from a person who has your number. 
Add the number and other contact info into a text, whether you type it in or copy and paste (an ability not many phones have) and finally send tat to the person's phone who you want it to be sent to. Or, if your phone has a direct "send to contact" feature for your data, you can select that."

I used this protocol as it allows for quick and easy access to your contact information from your phone. Texting the information on to the recipient is a quick and for the most part safe way of exchanging contact details over long distances. However most phones do not have integrated anti virus software. This means that undetected viruses can be transferred via text, this could then infect the recipients phone. A safer way to exchange contact details is via desktop or laptop, this is because they have build it firewalls and additional anti virus software such as Norton or Macafee can be used to scan emails for legitimacy or any possible viruses. If this were to e used to exchange contact info then you could still find the initial information via the phone's settings.
