Square's 'cashtags' get more specific for sending quick payments

Square's let you securely wire money via its (cringe-inducingly named) $Cashtags for a bit now, but the feature's gotten a little more streamlined as of late. Now, you can specify a dollar amount for payments by appending the 'tags with a number. For example:$RED/5 is a $5 donation toward AIDS research, as the payment company cleverly pointed out in its announcement tweet. Whether or not your pursuits are as noble are entirely up to you.
