The Chicago White Sox announced that Childhood Cancer Awareness Day, presented by CIBC, will take place on September 6 at 5:20 p.m. CT against the Minnesota Twins at Rate Field. ^[1] Approximately 100 children, including siblings of those impacted by pediatric cancer, will form a gold ribbon in center field during the pregame. ^[2] Christine O'Reilly, Executive Director of Chicago White Sox Charities, said the day provides families facing challenges an opportunity to enjoy time together and raise awareness. ^[3] Proceeds from gold T-shirt sales will benefit CWSC cancer research and treatment initiatives, and CWSC has donated more than $51 million to local nonprofits, including over $12 million for pediatric cancer. ^[4] According to Worrell, the real payments problem in a bank-based economy is not currency but identification and verification: confirming the seller's identity, that the transferred amount matches the agreed value, and that all individuals and institutions involved are legally constituted and regulated to international standards. ^[5] DeLisle Worrell, an economist, asserts that in a modern bank-based economy, all payments made via cheques, debit cards, online transfers, and other methods are executed by deducting value from the payer's bank account and adding it to the payee's bank account, without the use of any physical currency. ^[6] Worrell argues that the crucial difference between currency payments and bank-based payments is anonymity: currency provides anonymity and requires no information requirements, whereas bank-based payments are convenient and low-risk but demand extensive information about the buyer, seller, product, and the financial institution. ^[7] Worrell states that payment with currency (notes and coins) is a completely separate process that involves no banking services, and that a note such as a US$20 bill is self-verifying because it is designed with numerous security features. ^[8]
