• Upgrading account is very cheap, since pricing totally variable

To do - major

• Separate out all personal details, put into personalSettings, gitignore it so that personal details aren't spread around
• Ideally, have it call you if the transaction fails (i.e. no receipt received from it)
  • Hypothesis - it won't hang up on you without success. Test this.
• How test? Need to collude with a parking official, or see if the meter can give status update instead of a straight top-up

To do - minor

• Make it pretty
• Legally, one can't pay another's meter, so need a disclaimer if go public
• Recommend pay-by-phone sticker to users?
